Detailsinfo

A vulnerability classified as critical has been found in PostgreSQL up to 18.6. Affected is an unknown code block of the component pg_dump. The manipulation with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

SQL injection in PostgreSQL pg_dump allows an object creator to execute arbitrary SQL as the user restoring the dump, via an inherited column having a child-local not-null constraint whose name requires quoting. Within major version 18, minor versions before PostgreSQL 18.7 are affected. Versions before PostgreSQL 18 are unaffected.

The advisory is shared for download at postgresql.org. This vulnerability is traded as CVE-2026-116318 since 10/26/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1505.
