Summary
HAX CMS umożliwia zarządzanie mikrositami z backendami PHP lub NodeJs. W wersjach przed 26.0.0, punkt końcowy `saveFile` walidował rozszerzenia plików bez uwzględnienia wielkości liter, co pozwalało na zapisanie nazwy pliku na dysku w oryginalnej formie, ale reguła `.htaccess`, która wymusza `Content-Disposition: attachment` dla plików HTML, jest wrażliwa na wielkość liter.
Risk Assessment
W przypadku przesłania pliku HTML z dużą literą w rozszerzeniu, plik jest serwowany jako `text/html`, co pozwala na wykonanie osadzonego JavaScriptu, omijając zabezpieczenia wprowadzone dla CVE-2026-22704. To stwarza ryzyko wykonania nieautoryzowanego kodu w przeglądarkach użytkowników.
Recommendation
Zaleca się aktualizację HAX CMS do wersji 26.0.0 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto wprowadzić dodatkowe kontrole walidacji rozszerzeń plików przed ich zapisaniem na serwerze.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
- CVE-2026-124490Critical
OpenEMR before 8.3.0 contains a path traversal vulnerability in the RingCentral RCFaxClient disposeDocument() method of oe-module-faxsms that allows authenticated attackers to read and write arbitrary files via the file_path parameter. Attackers can use action=download to read credentials and source code, or action=setup with base64 content to write web-executable files for code execution.
Original NVD description (English source)
HAX CMS helps manage microsite universe with PHP or NodeJs backends. Prior to version 26.0.0 of HAX CMS PHP, the `saveFile` endpoint validates upload extensions case-insensitively and writes the filename to disk verbatim, but the `.htaccess` rule that forces `Content-Disposition: attachment` on HTML files is case-sensitive. An HTML file uploaded with an uppercase extension (`.HTML`, `.Html`, `.HTM`) is still served as `text/html` but the forced-download header never applies, so the browser renders it inline and executes any embedded JavaScript in the HAXcms origin. This bypasses the mitigation shipped for CVE-2026-22704. Version 26.0.0 contains a fix.
