EventStoreDB Vulnerability CVE-2024-26133
A vulnerability has been identified in the projections subsystem by the Event Store Ltd engineering team and has been fixed in this release.
Only database instances that use custom projections are affected by this vulnerability.
User passwords may become accessible to those who have access to the chunk files on disk, and users who have read access to system streams. Only users in the $admins group can access system streams by default.
Recommended action
- Upgrade EventStoreDB: Event Store Cloud customers follow the instructions in the cloud upgrade guide. Otherwise follow the instructions in the standard upgrade guide.
- Reset the passwords for current and previous members of $admins and $ops groups.
- If a password was reused in any other system, reset it in those systems to a unique password to follow best practices.
