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" } } ] } }
