Prior to 8.6.2, default.blade.php renders header_color and related branding color settings inside a CSS style block with HTML escaping that is insufficient for the CSS context, allowing a superadmin to inject arbitrary CSS that affects authenticated users on subsequent page loads when Content Security Policy is disabled. This issue is fixed in version 8.6.2.","published":"2026-07-10T19:45:14.984Z","modified":"2026-08-27T03:57:10.719565015Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"snipe/snipe-it","fixedVersion":"8.6.2"}],"fix":{"url":"https://github.com/grokability/snipe-it/commit/c31190a128ec96fb34000a2f27eae198b1a51d40","label":"grokability/snipe-it@c31190a"},"references":[{"type":"WEB","url":"https://github.com/grokability/snipe-it/releases/tag/v8.6.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55481.json"},{"type":"ADVISORY","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-w7qw-5wfv-gwx9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55481"},{"type":"FIX","url":"https://github.com/grokability/snipe-it/commit/c31190a128ec96fb34000a2f27eae198b1a51d40"},{"type":"FIX","url":"https://github.com/grokability/snipe-it/pull/19097"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T03:57:10.719565015Z"}}
