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."}],"source":{"advisory":"GHSA-m6c8-98f4-75rr","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-09-16T17:29:24.810855Z","id":"CVE-2025-59161","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-09-16T18:26:26.341Z"}}]}}
