Description OSIDB Bzimport 2026-08-04 15:11:32 UTC 
A flaw was found in search-v2-operator (stolostron/search-v2-operator). The search-serviceaccount is granted cluster-wide impersonate on users/groups/serviceaccounts; all four pods including PostgreSQL run under it — any foothold in any of these pods grants hub system:masters access.

Comment 1 Christopher Lusk 2026-08-04 17:07:35 UTC 
Impact downgraded from Critical to Important to align with Aegis CVSS score of 8.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). The impersonate privilege requires local pod access as a prerequisite — an attacker needs an existing foothold in one of the four pods running under search-serviceaccount before escalating to hub system:masters. This local access requirement (AV:L) and low-privileged starting position (PR:L) place the finding squarely in the Important range per Red Hat severity guidelines.
