ClawSec Feed 📡

Security advisory feed monitoring for AI agents. Subscribe to community-driven threat intelligence and stay informed about emerging threats. This feed is automatically updated daily with CVEs related to OpenClaw, clawdbot, and Moltbot from the NIST National Vulnerability Database (NVD). An open source project by Prompt Security

Installation Options

You can get clawsec-feed in two ways:

Option A: Bundled with ClawSec Suite (Recommended)

If you've installed clawsec-suite, you may already have this! ClawSec-feed is bundled alongside ClawSec Suite to provide crucial CVE and threat intelligence information. When you install the suite, if you don't already have the feed installed, it will be deployed from the bundled copy. Advantages: Convenient - no separate download needed Standard location - installed to ~/.openclaw/skills/clawsec-feed/ Preserved - if you already have feed installed, it won't be overwritten Single verification - integrity checked as part of suite package

Option B: Standalone Installation (This Page)

Install clawsec-feed independently without the full suite. When to use standalone: You only need the advisory feed (not other suite components) You want to install before installing the suite You prefer explicit control over feed installation Advantages: Lighter weight installation Independent from suite Direct control over installation process Continue below for standalone installation instructions. Installation Steps: Agents should review scripts before execution! # Get latest clawsec-feed release tag LATEST_TAG=$(curl -sSL https://api.github.com/repos/prompt-security/ClawSec/releases | \ jq -r '[.[] | select(.tag_name | startswith("clawsec-feed-v"))][0].tag_name') # Download SKILL.md from latest release SKILL_URL="https://github.com/prompt-security/clawsec/releases/download/$LATEST_TAG/SKILL.md" curl -sSL --fail --show-error "$SKILL_URL" Once you have this skill file, proceed to Deploy ClawSec Feed below.

Step 3: Add to your heartbeat

Add ClawSec Feed to your heartbeat routine: ## ClawSec Feed (every heartbeat) 1. Check advisory feed for new security alerts 2. Cross-reference with installed skills 3. Notify user if action is required

Step 4: Confirm deployment

• Tell your user:
• ClawSec Feed deployed successfully. I will now:
• Monitor the community advisory feed for threats
• Alert you to any security issues affecting your environment
• Keep you informed of emerging attack patterns

Advisory Feed Monitoring

Subscribes to the community advisory feed for: Known malicious skills/plugins - Skills that have been identified as harmful Prompt injection patterns - Attack patterns observed in the wild Vulnerable skill versions - Skills with known security flaws Security best practice updates - New recommendations for agent safety When a relevant advisory is published, your agent will notify you.

Checking the Advisory Feed

# Use environment variable if set, otherwise use raw GitHub feed (always up-to-date) DEFAULT_FEED_URL="https://raw.githubusercontent.com/prompt-security/ClawSec/main/advisories/feed.json" FEED_URL="${CLAWSEC_FEED_URL:-$DEFAULT_FEED_URL}" # Fetch with error handling and retry logic curl -sSL --fail --show-error --retry 3 --retry-delay 1 "$FEED_URL" Feed structure: { "version": "1.0", "updated": "2026-02-02T12:00:00Z", "advisories": [ { "id": "GA-2026-001", "severity": "critical", "type": "malicious_skill", "title": "Malicious data exfiltration in skill 'helper-plus'", "description": "Skill sends user data to external server", "affected": ["helper-plus@1.0.0", "helper-plus@1.0.1"], "action": "Remove immediately", "published": "2026-02-01T10:00:00Z", "exploitability_score": "critical", "exploitability_rationale": "Trivially exploitable through normal skill usage; no special conditions required. Active exploitation observed in the wild." } ] }

Get advisory count

# Use environment variable if set, otherwise use raw GitHub feed (always up-to-date) DEFAULT_FEED_URL="https://raw.githubusercontent.com/prompt-security/ClawSec/main/advisories/feed.json" FEED_URL="${CLAWSEC_FEED_URL:-$DEFAULT_FEED_URL}" TEMP_FEED=$(mktemp) trap "rm -f '$TEMP_FEED'" EXIT if ! curl -sSL --fail --show-error --retry 3 --retry-delay 1 "$FEED_URL" -o "$TEMP_FEED"; then echo "Error: Failed to fetch advisory feed" exit 1 fi # Validate JSON before parsing if ! jq empty "$TEMP_FEED" 2>/dev/null; then echo "Error: Invalid JSON in feed" exit 1 fi FEED=$(cat "$TEMP_FEED") # Get advisory count with error handling COUNT=$(echo "$FEED" | jq '.advisories | length') if [ $? -ne 0 ]; then echo "Error: Failed to parse advisories" exit 1 fi echo "Advisory count: $COUNT"

Get critical advisories

# Parse critical advisories with jq error handling CRITICAL=$(echo "$FEED" | jq '.advisories[] | select(.severity == "critical")') if [ $? -ne 0 ]; then echo "Error: Failed to filter critical advisories" exit 1 fi echo "$CRITICAL"

Get advisories from the last 7 days

# Use UTC timezone for consistent date handling WEEK_AGO=$(TZ=UTC date -v-7d +%Y-%m-%dT00:00:00Z 2>/dev/null || TZ=UTC date -d '7 days ago' +%Y-%m-%dT00:00:00Z) RECENT=$(echo "$FEED" | jq --arg since "$WEEK_AGO" '.advisories[] | select(.published > $since)') if [ $? -ne 0 ]; then echo "Error: Failed to filter recent advisories" exit 1 fi echo "$RECENT"

Filter by exploitability score

Shared exploitability prioritization guidance is maintained in: wiki/exploitability-scoring.md skills/clawsec-suite/SKILL.md ("Quick feed check")

Get exploitability context for an advisory

# Show exploitability details for a specific CVE CVE_ID="CVE-2026-27488" echo "$FEED" | jq --arg cve "$CVE_ID" '.advisories[] | select(.id == $cve) | { id: .id, severity: .severity, exploitability_score: .exploitability_score, exploitability_rationale: .exploitability_rationale, title: .title }'

Prioritize advisories by exploitability

# Sort advisories by exploitability (critical → high → medium → low) # This helps agents focus on the most immediately actionable threats echo "$FEED" | jq '[.advisories[] | select(.exploitability_score != null)] | sort_by( if .exploitability_score == "critical" then 0 elif .exploitability_score == "high" then 1 elif .exploitability_score == "medium" then 2 elif .exploitability_score == "low" then 3 else 4 end )'

Cross-Reference Installed Skills

Check if any of your installed skills are affected by advisories: # List your installed skills (adjust path for your platform) INSTALL_DIR="${CLAWSEC_INSTALL_DIR:-$HOME/.openclaw/skills}" # Use environment variable if set, otherwise use raw GitHub feed (always up-to-date) DEFAULT_FEED_URL="https://raw.githubusercontent.com/prompt-security/ClawSec/main/advisories/feed.json" FEED_URL="${CLAWSEC_FEED_URL:-$DEFAULT_FEED_URL}" TEMP_FEED=$(mktemp) trap "rm -f '$TEMP_FEED'" EXIT if ! curl -sSL --fail --show-error --retry 3 --retry-delay 1 "$FEED_URL" -o "$TEMP_FEED"; then echo "Error: Failed to fetch advisory feed" exit 1 fi # Validate and parse feed if ! jq empty "$TEMP_FEED" 2>/dev/null; then echo "Error: Invalid JSON in feed" exit 1 fi FEED=$(cat "$TEMP_FEED") AFFECTED=$(echo "$FEED" | jq -r '.advisories[].affected[]?' 2>/dev/null | sort -u) if [ $? -ne 0 ]; then echo "Error: Failed to parse affected skills from feed" exit 1 fi # Safely validate all installed skills before processing # This prevents shell injection via malicious filenames VALIDATED_SKILLS=() while IFS= read -r -d '' skill_path; do skill=$(basename "$skill_path") # Validate skill name BEFORE adding to array (prevents injection) if [[ "$skill" =~ ^[a-zA-Z0-9_-]+$ ]]; then VALIDATED_SKILLS+=("$skill") else echo "Warning: Skipping invalid skill name: $skill" >&2 fi done < <(find "$INSTALL_DIR" -mindepth 1 -maxdepth 1 -type d -print0 2>/dev/null) # Check each validated skill against affected list # Use grep -qF for fixed string matching (prevents regex injection) for skill in "${VALIDATED_SKILLS[@]}"; do # At this point, $skill is guaranteed to match ^[a-zA-Z0-9_-]+$ if echo "$AFFECTED" | grep -qF "$skill"; then echo "WARNING: Installed skill '$skill' has a security advisory!" # Get advisory details for this skill echo "$FEED" | jq --arg s "$skill" '.advisories[] | select(.affected[] | contains($s))' fi done If you find affected skills: Check the advisory for details and severity Notify your user immediately for critical/high severity Include the recommended action from the advisory

Prioritizing High-Exploitability Threats

IMPORTANT: When reviewing advisories, always prioritize by exploitability score in addition to severity. The exploitability score indicates how easily a vulnerability can be exploited in practice, helping you focus on the most actionable threats.

Exploitability Priority Levels

ExploitabilityMeaningAction PriorityhighTrivially or easily exploitable with public toolingImmediate notificationmediumExploitable but requires specific conditionsStandard notificationlowDifficult to exploit or theoreticalLow priority notification

How to Use Exploitability in Notifications

Filter for high-exploitability first: # Get high exploitability advisories echo "$FEED" | jq '.advisories[] | select(.exploitability_score == "high")' Include exploitability in notifications: 📡 ClawSec Feed: High-exploitability alert CRITICAL - CVE-2026-27488 (Exploitability: HIGH) → Trivially exploitable RCE in skill-loader v2.1.0 → Public exploit code available → Recommended action: Immediate removal or upgrade to v2.1.1 Prioritize by both severity AND exploitability: A HIGH severity + HIGH exploitability CVE is more urgent than a CRITICAL severity + LOW exploitability CVE Focus user attention on threats that are both severe and easily exploitable Include the exploitability rationale to help users understand the risk context

Example Notification Priority Order

When multiple advisories exist, present them in this order: Critical severity + High exploitability - most urgent High severity + High exploitability Critical severity + Medium/Low exploitability High severity + Medium/Low exploitability Medium/Low severity (any exploitability) This ensures you alert users to the most actionable, immediately dangerous threats first.

When to Notify Your User

Notify Immediately (Critical): New critical advisory affecting an installed skill Active exploitation detected High exploitability score (regardless of severity) Notify Soon (High): New high-severity advisory affecting installed skills Failed to fetch advisory feed (network issue?) Medium exploitability with high severity Notify at Next Interaction (Medium): New medium-severity advisories General security updates Low exploitability advisories Log Only (Low/Info): Low-severity advisories (mention if user asks) Feed checked, no new advisories Theoretical vulnerabilities (low exploitability, low severity)

If there are new advisories:

📡 ClawSec Feed: 2 new advisories since last check CRITICAL - GA-2026-015: Malicious prompt pattern "ignore-all" (Exploitability: HIGH) → Detected prompt injection technique. Update your system prompt defenses. → Exploitability: Easily exploitable with publicly documented techniques. HIGH - GA-2026-016: Vulnerable skill "data-helper" v1.2.0 (Exploitability: MEDIUM) → You have this installed! Recommended action: Update to v1.2.1 or remove. → Exploitability: Requires specific configuration; not trivially exploitable.

If nothing new:

FEED_OK - Advisory feed checked, no new alerts. 📡

State Tracking

Track the last feed check to identify new advisories: { "schema_version": "1.0", "last_feed_check": "2026-02-02T15:00:00Z", "last_feed_updated": "2026-02-02T12:00:00Z", "known_advisories": ["GA-2026-001", "GA-2026-002"] } Save to: ~/.openclaw/clawsec-feed-state.json

State File Operations

STATE_FILE="$HOME/.openclaw/clawsec-feed-state.json" # Create state file with secure permissions if it doesn't exist if [ ! -f "$STATE_FILE" ]; then echo '{"schema_version":"1.0","last_feed_check":null,"last_feed_updated":null,"known_advisories":[]}' > "$STATE_FILE" chmod 600 "$STATE_FILE" fi # Validate state file before reading if ! jq -e '.schema_version' "$STATE_FILE" >/dev/null 2>&1; then echo "Warning: State file corrupted or invalid schema. Creating backup and resetting." cp "$STATE_FILE" "${STATE_FILE}.bak.$(TZ=UTC date +%Y%m%d%H%M%S)" echo '{"schema_version":"1.0","last_feed_check":null,"last_feed_updated":null,"known_advisories":[]}' > "$STATE_FILE" chmod 600 "$STATE_FILE" fi # Check for major version compatibility SCHEMA_VER=$(jq -r '.schema_version // "0"' "$STATE_FILE") if [[ "${SCHEMA_VER%%.*}" != "1" ]]; then echo "Warning: State file schema version $SCHEMA_VER may not be compatible with this version" fi # Update last check time (always use UTC) TEMP_STATE=$(mktemp) if jq --arg t "$(TZ=UTC date +%Y-%m-%dT%H:%M:%SZ)" '.last_feed_check = $t' "$STATE_FILE" > "$TEMP_STATE"; then mv "$TEMP_STATE" "$STATE_FILE" chmod 600 "$STATE_FILE" else echo "Error: Failed to update state file" rm -f "$TEMP_STATE" fi

Rate Limiting

Important: To avoid excessive requests to the feed server, follow these guidelines: Check TypeRecommended IntervalMinimum IntervalHeartbeat checkEvery 15-30 minutes5 minutesFull feed refreshEvery 1-4 hours30 minutesCross-reference scanOnce per session5 minutes # Check if enough time has passed since last check STATE_FILE="$HOME/.openclaw/clawsec-feed-state.json" MIN_INTERVAL_SECONDS=300 # 5 minutes LAST_CHECK=$(jq -r '.last_feed_check // "1970-01-01T00:00:00Z"' "$STATE_FILE" 2>/dev/null) LAST_EPOCH=$(TZ=UTC date -j -f "%Y-%m-%dT%H:%M:%SZ" "$LAST_CHECK" +%s 2>/dev/null || date -d "$LAST_CHECK" +%s 2>/dev/null || echo 0) NOW_EPOCH=$(TZ=UTC date +%s) if [ $((NOW_EPOCH - LAST_EPOCH)) -lt $MIN_INTERVAL_SECONDS ]; then echo "Rate limit: Last check was less than 5 minutes ago.

Updating ClawSec Feed

Check for and install newer versions: # Check current installed version INSTALL_DIR="${CLAWSEC_INSTALL_DIR:-$HOME/.openclaw/skills/clawsec-feed}" CURRENT_VERSION=$(jq -r '.version' "$INSTALL_DIR/skill.json" 2>/dev/null || echo "unknown") echo "Installed version: $CURRENT_VERSION" # Check latest available version LATEST_URL="https://api.github.com/repos/prompt-security/ClawSec/releases" LATEST_VERSION=$(curl -sSL --fail --show-error --retry 3 --retry-delay 1 "$LATEST_URL" 2>/dev/null | \ jq -r '[.[] | select(.tag_name | startswith("clawsec-feed-v"))][0].tag_name // empty' | \ sed 's/clawsec-feed-v//') if [ -z "$LATEST_VERSION" ]; then echo "Warning: Could not determine latest version" else echo "Latest version: $LATEST_VERSION" if [ "$CURRENT_VERSION" != "$LATEST_VERSION" ]; then echo "Update available! Run the deployment steps with the new version." else echo "You are running the latest version." fi fi

Initial Download Integrity

Bootstrap Trust Problem: The initial download of this skill cannot be verified by the skill itself. To establish trust: Verify the source URL - Ensure you are downloading from https://clawsec.prompt.security Check release signatures - GitHub signs our releases; verify the release is from the checksums. Compare checksums - After download, compare the SHA-256 hash against the published checksums.json: # After downloading SKILL.md, verify its integrity EXPECTED_HASH="<hash-from-checksums.json>" ACTUAL_HASH=$(shasum -a 256 SKILL.md | cut -d' ' -f1) if [ "$EXPECTED_HASH" != "$ACTUAL_HASH" ]; then echo "ERROR: Skill file integrity check failed!" echo "This file may have been tampered with. Do not proceed." exit 1 fi Note: For maximum security, verify checksums.json via a separate trusted channel (e.g., direct from GitHub release page UI, not via curl).
