{"id":"CVE-2026-77825","details":"IBM ContextForge MCP Gateway 1.0.0 through 1.0.8 was vulnerable to path traversal in its Admin API log-download endpoint (`GET /v1/admin/logs/file`). The path confinement check uses `str.startswith()` rather than proper boundary validation, allowing an authenticated admin to read `.log`, `.jsonl`, and `.json` files outside the configured `LOG_FOLDER` by supplying a filename that resolves into a sibling directory whose absolute path shares the log directory's string prefix.","modified":"2026-10-01T08:03:06.671299Z","published":"2026-09-24T15:17:38.560Z","references":[{"type":"FIX","url":"https://www.ibm.com/support/pages/node/7289314"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ibm/mcp-context-forge","events":[{"introduced":"6f2dee5c2e74ecfbe88e0acd109b44e1fd3cfdd3"},{"fixed":"f909289b2f62a98e2076357bb79d12e80e4a7fed"}],"database_specific":{"cpe":"cpe:2.3:a:ibm:contextforge:*:*:*:*:*:python:*:*","extracted_events":[{"introduced":"1.0.0"},{"fixed":"1.0.9"}],"source":"CPE_RANGE"}}],"versions":["v1.0.7","v1.0.8","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77825.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N"}]}
