What is CVE-2026-2361?
CVE-2026-2361 is a high-severity vulnerability in DALIBO PostgreSQL Anonymizer, published on 11 Feb 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a temporary view based on a function containing malicious code. When the anon.get_tablesample_ratio function is then called, the malicious code is executed with superuser privileges. This privilege elevation can be exploited by users having the CREATE privilege in PostgreSQL 15 and later. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version because the creation permission on the public schema is granted by default. The problem is resolved in PostgreSQL Anonymizer 3.0.1 and further versions
Weakness: CWE-427
