{"id":"CVE-2026-50025","state":"PUBLISHED","title":"Mousehole: Unauthenticated HTTP/WebSocket boundary exposes and mutates MAM cookie state","description":"Mousehole is a background service to update a seedbox IP for MAM and web app to manage it. Prior to version 0.4.05, Mousehole's HTTP/WebSocket management boundary is reachable without application-layer authentication or browser/LAN provenance checks. The service stores a MyAnonamouse (MAM) session cookie in state and reuses the same cookie-bearing serialization for persisted state, public API responses, and WebSocket state updates. Any client that can reach the published Mousehole port can read cookie-bearing state, connect to WebSocket state updates, replace the stored cookie, or force MAM update side effects. The deployment examples publish port 5010 broadly with Docker's `5010:5010` syntax, which can make the issue reachable on mixed-trust LAN/VPN interfaces. Version 0.4.0 patches the issue.","publishedAt":"2026-09-11T20:42:00.058Z","updatedAt":"2026-09-14T20:00:04.091Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["t-mart mousehole"],"affected":[{"vendor":"t-mart","product":"mousehole","versions":[{"version":"< 0.4.0","status":"affected"}]}],"references":["https://github.com/t-mart/mousehole/security/advisories/GHSA-v64r-gfrc-f6vq","https://github.com/t-mart/mousehole/blob/master/CHANGELOG.md#v040---2026-06-04"],"weaknesses":["CWE-200","CWE-306","CWE-346","CWE-352","CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50025.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50025","state":"PUBLISHED","datePublished":"2026-09-11T20:42:00.058Z","dateUpdated":"2026-09-14T20:00:04.091Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-02T22:46:02.580Z"},"containers":{"cna":{"title":"Mousehole: Unauthenticated HTTP/WebSocket boundary exposes and mutates MAM cookie state","descriptions":[{"lang":"en","value":"Mousehole is a background service to update a seedbox IP for MAM and web app to manage it.
