CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HExplain CVE-2026-116318 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-116318?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-116318?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-116318 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.Opens a third-party assistant; its answer is its own, not cve.bz's.

Red Hat rates this Important.
This vulnerability is rated as Important due to the potential for privilege escalation, as an authenticated user with object creation permissions can execute arbitrary SQL commands with the elevated privileges of the administrator restoring the database dump. Although exploitation requires access to create schema objects, the resulting impact allows full administrative compromise of the target database during restoration workflows. Standard Red Hat Enterprise Linux releases package earlier major versions of PostgreSQL that do not contain the affected feature logic and are therefore unaffected.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
