CVE-2026-14680
HighCVSS 8.8Exploitation Probability (EPSS)
Low risk46th percentile - higher than 46% of all known CVEs
Summary
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.
Risk Assessment
Any database user can execute arbitrary code on the server, leading to full system compromise and data breach.
Recommendation
Immediately upgrade PostgreSQL to a patched version and consider restricting database access to trusted users only.
