CVE-2026-105613— PostgreSQL Anonymizer: Unbounded memory allocation (DoS) in range-based dummy functions

Quick assessment

Affected
DALIBO PostgreSQL Anonymizer
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

PostgreSQL Anonymizer 的基于范围的假值函数未对范围大小进行限制。攻击者可利用此漏洞耗尽后端进程的内存，并在开启内存超分配（overcommit）时触发 OOM 终止，进而导致整个集群执行崩溃恢复。该问题已在 PostgreSQL Anonymizer 3.3.0 及更高版本中修复。

Vulnerability Title
PostgreSQL Anonymizer: Unbounded memory allocation (DoS) in range-based dummy functions
Source: CVE Program / CVE List V5
Vulnerability Description
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.
