CVE-2026-11945 | PostgreSQL Anonymizer: SQL injection in the rules import functions

Exp

PostgreSQL Anonymizer contains a vulnerability that allows a user to gain superuser privileges by creating a JSON document and placing malicious code inside a particular key-value pair. If a superuser calls the import_database_rules() or import_roles_rules() functions, the malicious code is executed with superuser privileges. The problem is resolved in PostgreSQL Anonymizer 3.1.1 and further versions

CVSS metrics for this CVE.

Base score Version Severity Vector Exploitability Impact Score source
6.4 3.1 MEDIUM
CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:H)
They need powerful rights—admin, root, or similar—before this pays off.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.

A normal user session is enough; they don’t have to be admin.

Nobody has to click “OK” or open a trap file; it can work without a victim helping.
