description

OTRS 7.0.X, 8.0.X, and 2023.X through 2026.X before 2026.7.X may continue accepting issued login tokens after the associated account is disabled or its password is changed. An attacker who already possesses an unexpired token can continue operating with that account's permissions until the token expires.

mitigation

Upgrade OTRS 2026.X to 2026.7.X or later. For affected branches without a recorded fixed release, limit access for accounts with suspected token exposure and obtain an updated release from the supplier.
