CVE-2026-14680: Access of Resource Using Incompatible Type ('Type Confusion') in PostgreSQL
Type confusion with PostgreSQL "internal" data type arguments allows any user to execute arbitrary code as the operating system user running the database, via calls to functions with that argument type. Type "internal" represents a class of mutually-incompatible data structures not intended for access from SQL. The system intended to prevent such function calls, but this prevention had gaps. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
AI Analysis
Technical Summary
This vulnerability arises from type confusion related to PostgreSQL's internal data type arguments. The internal type is a special category of data structures that are mutually incompatible and not intended for direct SQL access. However, due to incomplete prevention controls, functions accepting internal type arguments can be called in a way that allows arbitrary code execution as the OS user running the database. The vulnerability affects PostgreSQL versions before 14.24, 15.19, 16.15, 17.11, and 18.5.
Potential Impact
Successful exploitation allows any database user to execute arbitrary code with the operating system privileges of the PostgreSQL server process. This can lead to full compromise of the database host environment, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is indicated in the provided data. Users should monitor PostgreSQL vendor advisories for patches addressing this vulnerability and apply updates promptly once available.
