On this page
Mediary Scout before 2026.11.05 contains a server-side request forgery vulnerability that allows any authenticated user, including non-owner accounts, to set an arbitrary PanSou base URL via savePanSouBaseUrlAction without role checks. Attackers can trigger probePanSou() to send server-side POST requests to internal hosts and use distinct error responses as an oracle for internal host and port discovery.

Explain CVE-2026-125359 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-125359?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-125359?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-2026-125359 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.
