Description Srikanth Balasubramanian 2026-09-03 09:27:18 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Untrusted search path in PostgreSQL amcheck allows a grantee of amcheck function EXECUTE privilege to execute arbitrary functions as the owners of expression indexes that depend on the search path, via setting a hostile search path before calling the amcheck function.  Within major versions 18, 16, 15, and 14, minor versions before PostgreSQL 18.5, 16.15, 15.19, and 14.24 are affected.  PostgreSQL 17 is unaffected.
