{"id":"CVE-2026-125341","published":"2026-11-10T20:19:08.703","lastModified":"2026-11-10T21:19:22.463","description":"Winter CMS is a content management system built on the Laravel PHP framework. From 1.1.0 until 1.2.14, Backend\\Widgets\\Lists::evalImageTypeValue() interpolates the result of ImageResizer::filterGetUrl() into a single-quoted image source attribute without escaping it. In a third-party plugin that renders an attacker-influenced value through an image list column, an unsupported image value is returned verbatim, can break out of the attribute, and can inject event handlers that execute when a backend user views the list. Winter core ships no image list column, so a default installation is unaffected. This issue is fixed in version 1.2.14.","cvssScore":2,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wintercms/winter/commit/0941c9816181095fe35d58e78e6d0c4a49238967","tags":[]},{"url":"https://github.com/wintercms/winter/releases/tag/v1.2.14","tags":[]},{"url":"https://github.com/wintercms/winter/security/advisories/GHSA-7mpf-4465-7fc2","tags":[]}],"exploitRefs":[{"url":"https://github.com/wintercms/winter/commit/0941c9816181095fe35d58e78e6d0c4a49238967","tags":[]},{"url":"https://github.com/wintercms/winter/releases/tag/v1.2.14","tags":[]},{"url":"https://github.com/wintercms/winter/security/advisories/GHSA-7mpf-4465-7fc2","tags":[]}],"hasPoc":true,"ai":null}
