DescriptionCVE.org

SQL injection in PostgreSQL EXTRACT() deparse allows an object owner to execute arbitrary SQL as a superuser via a hostile object definition. Attacks affect expression deparse consumers broadly, including pg_dump, psql commands like \sf, and any similar usage in non-core tools. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

AnalysisAI

SQL injection in PostgreSQL's EXTRACT() expression deparse enables a database object owner to escalate privileges and execute arbitrary SQL with superuser rights. Affected across the active PostgreSQL release tree - versions before 14.24, 15.19, 16.15, 17.11, and 18.5 - the flaw is triggered when deparse consumers such as pg_dump or psql's \sf command process a hostile object definition crafted by a low-privilege but authenticated database user. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to be an authenticated PostgreSQL database user with ownership of at least one database object (e.g., a function, operator, or custom type) in a database that a superuser or privileged DBA user will subsequently subject to a deparse consumer operation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The provided CVSS vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, 8.8) contains a significant internal conflict: PR:N (no privileges required) directly contradicts the description's explicit prerequisite of being a database 'object owner,' which requires authentication and object ownership - at minimum PR:L. … 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 Upgrade to the patched releases as the primary fix: PostgreSQL 18.5, 17.11, 16.15, 15.19, or 14.24, per the vendor advisory at https://www.postgresql.org/support/security/CVE-2026-15741/. … Detailed patch versions, workarounds, and compensating controls in full report.
