This is due to insufficient input sanitization in the user_meta_save() function (which only sanitizes array values, not scalar values) and improper output escaping in the Redux_Slider::render() method, which outputs slider values into unquoted HTML attributes. The vulnerability also exploits the fact that the clean_default() method only casts values to numeric types when they are empty or out of bounds, allowing malicious strings like '1 tabindex=0 autofocus onfocus=alert(1) x=' to pass validation through PHP's loose type comparison. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts into their user profile that will execute whenever an Administrator navigates to view the attacker's profile page." } ], "title": "Redux Framework <= 4.5.13.1 - Authenticated (Subscriber+) Stored Cross-Site Scripting via Slider Field Value", "references": [ { "url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/31c554cf-eee9-45a8-8fb6-198978620204?source=cve" }, { "url": "https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/fields/slider/class-redux-slider.php#L311" }, { "url": "https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.10/redux-core/inc/fields/slider/class-redux-slider.php#L311" }, { "url": "https://plugins.trac.wordpress.org/browser/redux-framework/trunk/redux-core/inc/extensions/users/class-redux-extension-users.php#L1018" }, { "url": "https://plugins.trac.wordpress.org/browser/redux-framework/tags/4.5.10/redux-core/inc/extensions/users/class-redux-extension-users.php#L1018" }, { "url": "https://github.com/reduxframework/redux-framework/pull/4112/changes" } ], "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": "h0xilo" } ], "timeline": [ { "time": "2026-04-02T06:49:25.000Z", "lang": "en", "value": "Vendor Notified" }, { "time": "2026-09-09T21:20:33.000Z", "lang": "en", "value": "Disclosed" } ] }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-09-10T12:55:47.555159Z", "id": "CVE-2026-5399", "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": "2026-09-10T12:55:57.736Z" } } ] } }
