Quick assessment
Affected
n/a PostgreSQL
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.

Vulnerability Title
PostgreSQL commutator or negator result-type confusion executes arbitrary code
Source: CVE Program / CVE List V5
Vulnerability Description
Type confusion in PostgreSQL operator commutator and negator links allows an object creator to execute arbitrary code as the operating system user running the database, via linking operators having different result types or creating inconsistent reciprocal links. Versions before PostgreSQL 18.7, 17.12, 16.16, 15.20, and 14.25 are affected.
