CVE-2026-55418: CWE-639: Authorization Bypass Through User-Controlled Key in labring FastGPTCVE-2026-55418 0 CVE-2026-55418 is an authorization bypass vulnerability in labring FastGPT, an open source AI knowledge base platform. Prior to version 4.15.0-beta5, two file handlers in FastGPT authorize unrelated resources but then use an S3 object key from the request without verifying team ownership. Since S3 object keys are global within the bucket and tenant IDs appear only as path segments, an attacker can supply another team's key to access their file contents via certain endpoints. This issue is fixed in version 4.15.0-beta5. Join the discussion | CVE Database V5 | 07/07/2026, 21:18:45 UTC Added: 07/07/2026, 21:44:48 UTC |
