CVE-2026-115513 · OpenCATS before 0.12.0 Stored XSS via MRU Navigation Panel
Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.
OpenCATS before 0.12.0 contains a stored cross-site scripting vulnerability that allows a low-privileged authenticated user to inject HTML/JavaScript payloads by setting a Candidate, Company, Contact, Job Order, or List name/title field, which is stored unsanitized and later rendered unescaped in the 'Recent' (MRU) navigation panel displayed on nearly every page via lib/MRU.php's getFormatted() function. Attackers can exploit this by crafting a malicious record name that executes arbitrary JavaScript in the session of any other user, including Site Administrators, who views the record, enabling session/cookie theft and privilege escalation to full administrative control.
