Doc Text:
A flaw was found in PostgreSQL. An authenticated database user can achieve arbitrary code execution with the privileges of the operating system user running the database due to a use-after-free vulnerability in the PL/Perl procedural language. This issue occurs when the final reference to a Perl array or hash is dropped while PostgreSQL is converting the object, resulting in memory corruption.

Description OSIDB Bzimport 2026-11-12 14:34:02 UTC
Use after free in PostgreSQL plperl allows an object creator to execute arbitrary code as the operating system user running the database, via dropping the final reference to a Perl array or hash while PostgreSQL is converting that object.  Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
