CVE-2026-9617
MediumCVSS 6.8Summary
PostgreSQL Anonymizer zawiera podatność, która pozwala użytkownikowi uzyskać uprawnienia superużytkownika poprzez stworzenie tabeli i umieszczenie złośliwego kodu w identyfikatorze kolumny. Jeśli superużytkownik wywoła funkcję k-anonimizacji, złośliwy kod zostanie wykonany z uprawnieniami superużytkownika.
Risk Assessment
Ryzyko jest wyższe w przypadku PostgreSQL 14 lub instancji zaktualizowanych z PostgreSQL 14 lub wcześniejszej wersji. W PostgreSQL 15 i nowszych domyślnie cofnieto uprawnienia do tworzenia w publicznym schemacie, co ogranicza możliwość wykorzystania tej podatności.
Recommendation
Zaleca się aktualizację do PostgreSQL Anonymizer w wersji 3.1.0 lub nowszej, aby usunąć tę podatność. Należy również rozważyć ograniczenie przyznawania uprawnień CREATE TABLE użytkownikom.

Original NVD description (English source)
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
