CVE-2026-92603

38th percentile - higher than 38% of all known CVEs

ContiNew Admin through 4.1.0 contains an authorization bypass vulnerability in the personal message delete endpoint that allows authenticated users to delete other users' messages and announcements. Attackers can supply arbitrary message identifiers in the IdsReq parameter to remove any message row and purge all recipients' read receipts without ownership validation.

An attacker can delete other users' messages and announcements, causing data loss and disruption of communication within the organization. The lack of ownership validation enables mass and uncontrolled deletion of content.

Update ContiNew Admin to a version later than 4.1.0. Until the update is applied, restrict permissions to the message delete endpoint and monitor for unusual deletion operations.
