MEDIUM OTRS AG CVE published 2026-05-31

CVE-2026-48210

An improper default configuration in OTRS 2026.3.1 causes ticket article forwarding actions to enforce the “Is visible for customer” flag by default and prevent users from disabling it via the UI. This leads to unintended exposure of internal ticket information to the External Frontend.
