CVE-2026-46398 PUBLISHED

HAX CMS Missing Secure Flag on Cookie

Assigner: GitHub_M
Reserved: 13.05.2026 Published: 05.06.2026 Updated: 05.06.2026

HAX CMS helps manage microsite universe with PHP or NodeJs backends. Starting in version 25.0.0 and prior to version 26.0.0, the haxcms_refresh_token cookie is set without the Secure flag. This allows it to be transmitted over unencrypted HTTP, making it vulnerable to theft via packet sniffing on the network. Version 26.0.0 fixes the issue.
