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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
