CVE-2026-123624 · Other
NO FIX YET · SEE WHAT TO DO
ChatWiki before 2.10.0 lets any logged-in user change another tenant's fast commands by guessing sequential record ids sent to the save endpoint. An attacker can rewrite a command's content and point webpage-jump commands at attacker-controlled URLs, then reassign the record to their own tenant.

Any ChatWiki deployment running a version before 2.10.0 with more than one tenant, since the flaw lets an authenticated user act on records owned by other tenants. Single-tenant use with no untrusted accounts carries much less risk, but the sources do not say how the tenant model is configured by default.
