Formwork vulnerabilities

A security vulnerability has been detected in getformwork formwork up to 2.3.12. Impacted is the function DomSanitizer::sanitizeNodeAttribute of the file formwork/src/Sanitizer/DomSanitizer.php of the component URI Sanitizer. Such manipulation of the argument formaction leads to cross site scripting. The attack may be launched remotely.

Formwork before 2.3.13 contains a path traversal vulnerability in BackupController that allows authenticated panel users to read or delete arbitrary files. Attackers with backup download or delete permission can supply a base64-encoded backslash-separated traversal payload that bypasses PHP basename on Linux to access files outside the backup directory.

Formwork before 2.3.11 contains a stored cross-site scripting vulnerability in visit tracking that records the Referer header host unescaped. Unauthenticated attackers can craft malicious Referer headers to inject markup that executes in administrator browsers when viewing the Statistics panel.

Formwork, a flat file-based CMS, prior to version 2.2.0 allows insertion of unsanitized data into the blog tag field, resulting in stored XSS. Any user with Formwork credentials who views or edits an affected blog post will have attacker-controlled script executed in their browser.
