{"id":"CVE-2026-120658","kind":"vulnerability","aliases":["CVE-2026-120658"],"related":[],"title":"WordPress Download Manager plugin: stored cross-site scripting via file previews","description":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'file[additional_previews][]' parameter in all versions up to, and including, 7.6.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The wpdm_sanitize_array() function strips HTML tags via wp_kses but leaves bare single quotes intact and calls stripslashes_deep() which defeats WordPress magic quotes protection, allowing a single-quote-based attribute breakout payload to be stored verbatim and later rendered without escaping.","summary":"The Download Manager plugin for WordPress stores attacker-supplied script in the additional previews upload field and renders it without escaping. An author-level user can make scripts run in the browser of anyone who opens an affected page, such as an administrator.","severity":"medium","cvss":6.4,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"Download Manager","fixed":[],"affected":"","ecosystem":"vendor"}],"ecosystems":["vendor"],"tags":["download-manager","package","wordpress","wp-plugin"],"not_affected_if":["no-untrusted-authors","plugin-not-installed"],"how_to_check":"- Check the installed Download Manager plugin version in the WordPress admin under Plugins; versions up to and including `7.6.3` are affected.\n- Review pages and downloads for injected script in previews if authors are not fully trusted.","fix":null,"status":"open","published_at":"2026-11-13T10:17:26+00:00","first_seen_at":"2026-11-13T10:47:11+00:00","triaged_at":"2026-11-13T10:55:07+00:00","updated_at":"2026-11-13T10:55:07+00:00","category":"package","confidence":0.7,"triage":{"at":"2026-11-13T10:55:07Z","model":"claude-haiku-5-5","output":{"fix":"unknown","reach":"internet","title":"WordPress Download Manager plugin: stored cross-site scripting via file previews","impact":"medium","summary":"The Download Manager plugin for WordPress stores attacker-supplied script in the additional previews upload field and renders it without escaping.
