Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated user with legitimate access to the Bun.serve API endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents moderate real-world risk despite the 5.3 CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with legitimate API credentials (e.g., a compromised internal API key or a disgruntled insider) crafts a request to the Bun.serve endpoint with a crafted pathname parameter such as `../../etc/passwd` or `../../.env`. The buildCache.js handler processes this pathname without sanitization and retrieves the requested file from the server's filesystem. … |
| Remediation | No vendor-released patch is available, as the maintainer has not responded to early disclosure and continues rolling releases without tagged security fixes. … Detailed patch versions, workarounds, and compensating controls in full report. |
