This is due to the `arv_lb_options_val()` sanitize callback returning user input without any sanitization, and the stored `message` value being output in the `genLB()` function without escaping. This makes it possible for authenticated attackers, with Administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses a page or post with the lightbox enabled."}],"title":"Multi Functional Flexi Lightbox <= 1.2 - Authenticated (Admin+) Stored Cross-Site Scripting via 'message' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a4c0b14a-d039-4008-a433-ab3605e2612c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/multi-functional-flexi-lightbox/tags/1.2/sp.php#L37"},{"url":"https://plugins.trac.wordpress.org/browser/multi-functional-flexi-lightbox/tags/1.2/options.php#L94"},{"url":"https://plugins.trac.wordpress.org/browser/multi-functional-flexi-lightbox/trunk/sp.php#L37"},{"url":"https://plugins.trac.wordpress.org/browser/multi-functional-flexi-lightbox/trunk/options.php#L94"}],"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:H/UI:N/S:C/C:L/I:L/A:N","baseScore":5.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"san6051"}],"timeline":[{"time":"2026-03-20T15:13:42.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-03-24T13:54:45.424292Z","id":"CVE-2026-3347","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":"2026-03-24T13:54:57.501Z"}}]}}
