Untrusted search path in PostgreSQL amcheck allows a grantee of amcheck function EXECUTE privilege to execute arbitrary functions as the owners of expression indexes that depend on the search path, via setting a hostile search path before calling the amcheck function. Within major versions 18, 16, 15, and 14, minor versions before PostgreSQL 18.5, 16.15, 15.19, and 14.24 are affected. PostgreSQL 17 is unaffected.
This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 3.8, indicating it can be exploited remotely over the network with relatively low complexity without requiring user interaction . The vulnerability impacts limited data confidentiality, limited integrity, for affected systems. Impacting 1 product from postgresql organizations running these solutions should prioritize assessment and patching.
Reported in 2026, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For postgresql's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
