Vulnerabilities

CVE-2025-6851unauthenticated≤ 1.3.0
Broken Link Notifier <= 1.3.0 - Unauthenticated Server-Side Request Forgery
Medium 6.5
CVE-2026-25408unauthenticated≤ 1.3.5

Medium 5.3
CVE-2025-6838contributor+≤ 1.3.0
Broken Link Notifier <= 1.3.0 - Authenticated (Contributor+) CSV Injection
Medium 4.1

The access label is read from the record's own text (e.g. “subscriber+”: subscriber and above). When the text names no role, CVSS decides between “login required” and “high privilege”; no role name is invented. “Needs a click”: the attack depends on a logged-in user following a link (CSRF, reflected XSS).
