{"id":"CVE-2025-12544","kind":"vulnerability","aliases":["CVE-2025-12544"],"related":[],"title":"Publisher portal: uploaded SVG files can carry scripts to other users' browsers","description":"The Publisher portal fails to enforce proper validation on uploaded SVG files, allowing users with the Publisher role to inject malicious scripts. This weakness can be exploited by uploading a crafted SVG file, which is then stored and rendered by the application.\n\nThe security consequences include the ability for a malicious actor to redirect the victim's browser to an arbitrary website, modify the web page's UI, or retrieve information from the browser. However, the impact is mitigated as session-related sensitive cookies are protected with the httpOnly flag, preventing session hijacking.","summary":"The Publisher portal does not validate uploaded SVG files, so a user with the Publisher role can upload a crafted SVG that is stored and rendered. When a victim views it, the script can redirect their browser, alter the page, or read information from the browser, though httpOnly session cookies limit session hijacking.","severity":"medium","cvss":4.8,"epss":null,"exploited":false,"exploited_at":null,"products":[],"ecosystems":[],"tags":["other","publisher-portal","svg-upload"],"not_affected_if":["no-publisher-role-users","no-svg-upload"],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-11-02T11:17:30+00:00","first_seen_at":"2026-11-02T11:22:53+00:00","triaged_at":"2026-11-02T11:24:21+00:00","updated_at":"2026-11-02T11:24:21+00:00","category":"other","confidence":0.5,"triage":{"at":"2026-11-02T11:24:21Z","model":"claude-haiku-5-5","output":{"fix":"unknown","reach":"network","title":"Publisher portal: uploaded SVG files can carry scripts to other users' browsers","impact":"medium","summary":"The Publisher portal does not validate uploaded SVG files, so a user with the Publisher role can upload a crafted SVG that is stored and rendered.
