{"cve":"CVE-2026-14343","nvd":{"published":"2026-07-09T08:16:47.207","modified":"2026-07-09T18:16:50.297","status":"Deferred","description":"The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'note_before' and 'note_after' Shortcode Attributes in all versions up to, and including, 3.3.61 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Because wp_kses_post filters post content on save for users without unfiltered_html, only kses-allowed tag and attribute payloads that survive save-time filtering will reach the unescaped sink; however, the sink itself remains unsafe and such payloads can still execute in the browser when a user renders the shortcode.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.61/src/User/Register.php#L123","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.61/src/User/Register.php#L32","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.61/src/User/views/reg-form.php#L69","https://plugins.trac.wordpress.org/browser/download-manager/tags/3.3.61/src/User/views/reg-form.php#L78","https://plugins.trac.wordpress.org/changeset?reponame=&old=3594267%40download-manager&new=3594267%40download-manager"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-14343","score":0.00349,"percentile":0.28546,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
