Remote, unauthenticated, low-complexity forgery of any user's session against default config gives PR:N/AC:L; full account impersonation and apiKey theft yield C:H and I:H, no availability impact.

clawvet self-hosted API server (apps/api) before 0.7.5 hard-codes a fallback JWT secret ('clawvet-dev-secret-change-me') in auth.ts and ships it as the default in .env.example. Because GET /api/v1/scans returns scan records containing userId values without authentication, a remote unauthenticated attacker can harvest a victim's userId, forge a valid HS256 cg_session cookie offline using the known secret, and call GET /api/v1/auth/me to obtain the victim's email address, subscription plan, and secret apiKey. The published clawvet npm package (CLI only) is not affected.
AnalysisAI
Session forgery in the clawvet self-hosted API server (apps/api) before 0.7.5 lets a remote unauthenticated attacker fully impersonate any user and steal their secret apiKey. The server ships a hard-coded fallback JWT secret ('clawvet-dev-secret-change-me') in auth.ts and .env.example, while an unauthenticated GET /api/v1/scans endpoint leaks victim userId values; combining these, an attacker forges a valid HS256 cg_session cookie offline and calls GET /api/v1/auth/me to exfiltrate the victim's email, subscription plan, and API key. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the clawvet self-hosted API server (apps/api, version < 0.7.5) be deployed with the default/fallback JWT secret still in effect - i.e., the operator did not override JWT_SECRET and left the value shipped in .env.example ('clawvet-dev-secret-change-me'). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are consistent and point to a genuinely high-priority issue for anyone running the self-hosted API on defaults. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote attacker with no credentials calls GET /api/v1/scans on an exposed clawvet API server, reads a victim's userId from the returned scan records, and locally signs an HS256 cg_session cookie using the publicly-known secret 'clawvet-dev-secret-change-me'. Presenting that forged cookie to GET /api/v1/auth/me, the attacker retrieves the victim's email address, subscription plan, and secret apiKey, then reuses the stolen apiKey to access the victim's account and data. … |
| Remediation | Upgrade the self-hosted API server to clawvet 0.7.5 or later, which is the vendor-released patch that removes the hard-coded fallback JWT secret; see GHSA-9mww-p953-jfc9 (https://github.com/MohibShaikh/clawvet/security/advisories/GHSA-9mww-p953-jfc9). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all production clawvet self-hosted API deployments and immediately rotate all user API keys and credentials as a precautionary measure. …
