Summary
The external frontend system uses numerous background calls to the backend. Each background request is treated as user activity so the SessionMaxIdleTime will not be reached. This issue affects: OTRS 7.0.x version 7.0.14 and prior versions.
Exploit prediction
0.75% chance of exploitation in the next 30 days, higher than 55% of all scored CVEs (FIRST EPSS, 2026-11-08).
