Doc Text:
A flaw was found in PostgreSQL. A use-after-free memory flaw in the PL/Perl (plperl) procedural language extension allows an authenticated database user with object creation privileges to execute arbitrary code as the operating system user running the database service. This issue occurs when re-entering the plperl environment and freeing a prepared database query while an outer invocation is actively executing it.

Description OSIDB Bzimport 2026-11-12 14:33:31 UTC
Use after free in PostgreSQL plperl allows an object creator to execute arbitrary code as the operating system user running the database, via re-entering plperl and freeing a prepared query while an outer invocation is executing it.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
