Security readout for executives and security teams
Plain-English summary
A flaw in clawvet’s self-hosted API can let an unauthenticated remote attacker impersonate users and access sensitive account data, including email addresses, subscription details, and API keys. The issue combines exposed user identifiers with a predictable JWT signing secret. The CLI-only npm package is not affected.
Executive priority
Treat internet-accessible or default-configured deployments as an immediate remediation priority. The vulnerability can expose reusable API credentials and enable account impersonation without victim interaction. Upgrade, rotate secrets and API keys, invalidate sessions, and investigate possible misuse. CLI-only installations do not require action for this CVE.
Technical view
Before version 0.7.5, clawvet’s apps/api server uses a hard-coded fallback JWT secret also published in its example environment configuration. An unauthenticated scans endpoint exposes user identifiers, enabling offline creation of trusted HS256 session cookies. These sessions can access the authentication profile endpoint and disclose victim account information and API keys.
Likely exposure
Self-hosted clawvet API deployments running versions earlier than 0.7.5 are affected, particularly when remotely reachable and using the fallback or documented default secret. Deployments containing only the published CLI npm package are not affected. The supplied evidence does not establish how many vulnerable servers are publicly accessible.
Exploitation context
Exploitation is remotely feasible without authentication, privileges, or user interaction, according to the supplied advisories. The attack can compromise confidentiality and integrity but is not described as affecting availability. This CVE is not listed as KEV, and the supplied sources do not confirm active exploitation in the wild.
Researcher notes
The reported chain depends on two weaknesses: unauthenticated disclosure of user identifiers and a known symmetric JWT secret. Assessment should distinguish the self-hosted apps/api server from the unaffected CLI package. The supplied CVSS 4.0 score is 9.3. No CPEs, public exploitation confirmation, or deployment-prevalence data were provided.
Mitigation direction
- Upgrade the self-hosted clawvet API server to version 0.7.5 or later.
- Replace any fallback or example JWT secret with a unique, securely generated secret.
- Invalidate existing sessions after changing the JWT signing secret.
- Rotate potentially exposed API keys and investigate their prior use.
- Review the vendor advisory for additional remediation guidance.
Validation and detection
- Inventory deployments and confirm whether the self-hosted apps/api component is present.
- Verify every deployed API server reports version 0.7.5 or later.
- Confirm production configuration does not use the fallback or example JWT secret.
- Test that scan records and user identifiers are not exposed without authorization.
- Review logs for suspicious session activity and unexpected API-key use.
