CVE-2026-9617 (GCVE-0-2026-9617)

Vulnerability from cvelistv5 – Published: 2026-05-27 13:55 – Updated: 2026-05-27 15:27

Title

PostgreSQL Anonymizer: malicious column name allows SQL injection via anon.k_anonymity() function

Summary

PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a table and placing malicious code inside a column identifier. If a superuser calls the k-anonymity function, the malicious code is executed with superuser privileges. The risk is higher with PostgreSQL 14 or with instances upgraded from PostgreSQL 14 or a prior version. With PostgreSQL 15 and later, the creation permission on the public schema is revoked by default and this exploit can only be achieved by a user who was explicitly granted the CREATE TABLE privilege. The problem is resolved in PostgreSQL Anonymizer 3.1.0 and further versions

Severity

6.8 (Medium)
