This led to misbehaviors when a PL procedure issued COMMIT but a failure occurred (such as a deferred constraint check). To improve matters, redefine SPI_commit() as starting a new transaction, so that it becomes equivalent to SPI_commit_and_chain() except that you get default transaction characteristics instead of preserving the prior transaction's characteristics. To make this somewhat transparent API-wise, redefine SPI_start_transaction() as a no-op. All known callers of SPI_commit() immediately call SPI_start_transaction(), so they will not notice any change. Similar remarks apply to SPI_rollback().

An attack requires permission to create non-temporary objects in at least one schema, ability to lure or wait for an administrator to create or update an affected extension in that schema, and ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS . Given all three prerequisites, the attacker can run arbitrary code as the victim role, which may be a superuser. Known-affected extensions include both PostgreSQL-bundled and non-bundled extensions. PostgreSQL is blocking this attack in the core server, so there's no need to modify individual extensions.\n\nThe PostgreSQL project thanks Sven Klemm for reporting this problem.", "first_published": "2022-08-11", "fixed_version": "12.12"}], "cve_available": true, "remaining_cves": [], "security_regressions": [], "warnings": [], "candidate_count": 39, "already_in_source_count": 0, "duplicate_count": 0, "excluded_count": 0, "exclusions": [], "source_as_of": "2026-09-26", "security_as_of": "2026-09-26"}
