Summary

HAX CMS allows you to manage your microsite universe with PHP or NodeJs backends. In versions 11.0.13 and below of haxcms-nodejs and versions 11.0.8 and below of haxcms-php, API endpoints do not perform authorization checks when interacting with a resource. Both the JS and PHP versions of the CMS do not verify that a user has permission to interact with a resource before performing a given operation. The API endpoints within the HAX CMS application check if a user is authenticated, but don't check for authorization before performing an operation. This is fixed in versions 11.0.14 of haxcms-nodejs and 11.0.9 of haxcms-php.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
