{"id":"CVE-2026-50025","summary":"Mousehole: Unauthenticated HTTP/WebSocket boundary exposes and mutates MAM cookie state","details":"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.","aliases":["GHSA-v64r-gfrc-f6vq"],"modified":"2026-09-13T03:46:02.899650805Z","published":"2026-09-11T20:42:00.058Z","database_specific":{"cwe_ids":["CWE-200","CWE-306","CWE-346","CWE-352","CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50025.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/t-mart/mousehole/blob/master/CHANGELOG.md#v040---2026-06-04"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50025.json"},{"type":"ADVISORY","url":"https://github.com/t-mart/mousehole/security/advisories/GHSA-v64r-gfrc-f6vq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50025"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/t-mart/mousehole","events":[{"introduced":"0"},{"fixed":"2df38fbc03938630799a3df65ce15ab438b81dff"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.4.0"}],"source":"AFFECTED_FIELD"}}],"versions":["v0.3.1","v0.3.0","v0.2.0","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-50025.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
