Lifecycle Timeline
4DescriptionCVE.org
A vulnerability was identified in Gitlawb openclaude up to 0.30.0. Impacted is the function waitForCallback of the file src/services/api/xaiOAuthCallback.ts of the component xAI OAuth Callback Handler. The manipulation of the argument Error leads to denial of service. Remote exploitation of the attack is possible. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Denial-of-service in Gitlawb openclaude (all versions up to 0.30.0) arises from improper resource handling in the waitForCallback function of the xAI OAuth Callback Handler (src/services/api/xaiOAuthCallback.ts), where a manipulated Error argument causes availability degradation. The attack is network-reachable but requires user interaction (CVSS 4.0 UI:P), resulting in a low availability impact with no confidentiality or integrity consequences. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target deployment has the xAI OAuth authentication feature active and reachable - specifically, the `waitForCallback` function in `src/services/api/xaiOAuthCallback.ts` must be exposed to network traffic. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The overall risk is low despite the existence of a public proof-of-concept. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch has been identified at time of analysis; the project maintainer has not responded to the coordinated disclosure reported via GitHub issue #2101. … Detailed patch versions, workarounds, and compensating controls in full report. |
