DescriptionCVE.org

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.

AnalysisAI

Type confusion in PostgreSQL's 'internal' pseudo-type enforcement enables any authenticated database user to execute arbitrary code as the operating system user running the database process. The vulnerability arises because access controls blocking SQL-layer callers from invoking C-language functions that accept 'internal' arguments contained coverage gaps, allowing a crafted function call to corrupt memory and achieve OS-level code execution. …

Vulnerability AssessmentAI

Exploitation Exploitation requires exactly one prerequisite: a valid PostgreSQL database login of any privilege level, including accounts granted only SELECT on specific tables or minimal default privileges. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 8.8 score accurately reflects the severity of this vulnerability: any low-privileged authenticated user reachable over the network can achieve full OS-level code execution with no race conditions or special configurations required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary and complete fix is to upgrade to one of the patched releases: PostgreSQL 18.5, 17.11, 16.15, 15.19, or 14.24, as documented at https://www.postgresql.org/support/security/CVE-2026-14680/. … Detailed patch versions, workarounds, and compensating controls in full report.
