CVE-2026-107193
Description
A flaw has been found in permission filters in the foreman package. The API loads a filter by its identifier and does not apply the search limit on the caller's permission. A low-privileged network attacker or user must already be allowed to delete filters for one role only. They can delete filters that belong to other unlocked roles. Those other roles then lose the access the deleted filters had granted.
Statement
Red Hat Product Security has rated this vulnerability with a Moderate security impact. This vulnerability affects Foreman's permission-filter handling.
A caller must already hold a permission to delete filters that is limited by a search, such as to a single role. This is the documented way to delegate administration of filters for one role. The caller can delete filter records on unlocked roles outside their search. Those roles lose the permissions the filters granted. That is a direct change to who can do what in Foreman.
The vulnerable code was introduced in Foreman 1.19.0 when filter display was changed to ignore. All Foreman versions from 1.19.0 onward contain this lookup.
Mitigation
Filter creation, update, and deletion are audited with the role. Review recent filter audit records for deletions and role changes by delegated filter administrators. Removing those two permissions from delegated roles, or leaving them unlimited and held only by fully trusted administrators, closes the path until a fix is available.
