CVE-2026-105613
PostgreSQL Anonymizer: Unbounded memory allocation (DoS) in range-based dummy functions
CVSS Score
4.7
EPSS Score
0.0%
EPSS Percentile
0th
PostgreSQL Anonymizer's range-based dummy functions dont constraint the range size. This vulnerability can be exploited to exhaust the memory of a backend and OOM-kill it (when ovecommit is on), which results in a cluster-wide crash recovery. The problem is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
