This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes (notably 'window', 'class', and 'label') in the FrmKinetic::link() function, which are concatenated directly into HTML attributes of an anchor tag. 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":"Formidable Kinetic <= 1.1.01 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6f849ec6-1c90-4f98-a367-fea87ddc5870?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/formidable-kinetic/trunk/formidable-kinetic.php#L70"},{"url":"https://plugins.trac.wordpress.org/browser/formidable-kinetic/trunk/formidable-kinetic.php#L34"}],"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":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-05-26T17:25:45.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-27T10:22:17.435171Z","id":"CVE-2026-8871","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":"2026-05-27T10:35:27.070Z"}}]}}
