{"id":"CVE-2025-59161","state":"PUBLISHED","title":"In Element Web and Element Desktop, a malicious room can hide an unrelated room and cause it to be left when the malicious room is left","description":"Element Web is a Matrix web client built using the Matrix React SDK. Element Web and Element Desktop before version 1.11.112 have insufficient validation of room predecessor links, allowing a remote attacker to attempt to impermanently replace a room's entry in the room list with an unrelated attacker-supplied room. While the effect of this is temporary, it may still confuse users into acting on incorrect assumptions. The issue has been patched and users should upgrade to 1.11.112. A reload/refresh will fix the incorrect room list state, removing the attacker's room and restoring the original room.","publishedAt":"2025-09-16T16:44:15.660Z","updatedAt":"2025-09-16T18:26:26.341Z","severity":{"score":2.7,"label":"Low","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/E:U","source":"GitHub_M"},"assigner":"GitHub_M","products":["element-hq element-web"],"affected":[{"vendor":"element-hq","product":"element-web","versions":[{"version":"< 1.11.112","status":"affected"}]}],"references":["https://github.com/element-hq/element-web/security/advisories/GHSA-m6c8-98f4-75rr","https://github.com/element-hq/element-web/commit/8e9a43d70c90e6a3b110cd0a377296079e4c81f5"],"weaknesses":["CWE-20"],"ingestedAt":"2026-10-29T20:09:39.787Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/59xxx/CVE-2025-59161.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-59161","state":"PUBLISHED","datePublished":"2025-09-16T16:44:15.660Z","dateUpdated":"2025-09-16T18:26:26.341Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-09-09T15:23:16.327Z"},"containers":{"cna":{"title":"In Element Web and Element Desktop, a malicious room can hide an unrelated room and cause it to be left when the malicious room is left","descriptions":[{"lang":"en","value":"Element Web is a Matrix web client built using the Matrix React SDK.
