This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes, specifically the 'url', 'color', and 'bgcolor' parameters. These attribute values are directly interpolated into HTML attribute context without being passed through esc_attr() or any other escaping function. 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."}],"title":"ZeM STL <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/07e415f9-42f1-4c80-a023-38f460f634d3?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/trunk/zemstl.php#L107"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/tags/1.0/zemstl.php#L107"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/trunk/zemstl.php#L74"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/tags/1.0/zemstl.php#L74"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/trunk/zemstl.php#L103"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/tags/1.0/zemstl.php#L103"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/trunk/zemstl.php#L104"},{"url":"https://plugins.trac.wordpress.org/browser/zem-stl-viewer/tags/1.0/zemstl.php#L104"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Gilang Asra Bilhadi"}],"timeline":[{"time":"2026-06-01T19:45:23.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-02T10:38:25.568498Z","id":"CVE-2026-4081","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-02T10:47:34.271Z"}}]}}
