High (8.6) in zenitel zenitel connect.
On this page
The pREST database REST API in Zenitel Connect firmware before 1.11.0 signs and verifies JWTs with the platform CA private key, which is stored on a data volume shared between containers, and sets the PostgreSQL session role from the unvalidated sub claim of each request while connected to the database as the "postgres" superuser, which allows local attackers who can read the platform CA private key from the container filesystem to execute database operations as the PostgreSQL superuser, including reading the master encryption key and password hashes, via a forged JWT with sub=postgres sent to the pREST API.

Explain CVE-2026-95613 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-95613?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-95613?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-2026-95613 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.
