Protected-object count disclosure via permission filter failure
Published Jun 1, 2026 · Updated Jun 1, 2026
Permission handling in OTRS STORM Document Search Article Meta Filters allows remote authenticated users to learn protected object counts. The flaw lies in permission handling for the module's metadata filters, but OTRS has not disclosed the faulty check or code path. Low-privileged network access and user interaction are required, and the result reveals only affected-object counts rather than access to the protected objects.
