CVE-2026-105614: PostgreSQL Anonymizer image_blur function memory exhaustion

CVE-2026-105614 · Severity: medium · CVSS 4.7 · Published 2026-10-28

PostgreSQL Anonymizer is a plugin that adds data anonymization capabilities to PostgreSQL databases. A flaw in its image_blur() function allows an attacker to trigger out-of-memory conditions by providing images with falsely declared dimensions, causing the database server to crash and requiring cluster-wide recovery.

Technologies: Dalibo PostgreSQL Anonymizer. Vendors: Dalibo.

Technical details

The anon.image_blur() function fails to validate the declared dimensions of provided images before processing, allowing an attacker to supply a small image with an enormous declared size. This causes the backend to allocate excessive memory for image processing, leading to OOM-kill conditions when memory overcommit is enabled and resulting in a denial of service affecting the entire database cluster.

Affected products

  • Dalibo PostgreSQL Anonymizer before 3.3.0
