Summary

myTinyWMS is a free, open-source warehouse management system. Prior to version 1.6.4, `Product (Artikel)` and `Category` management store the `name` parameter without adequate backend sanitization and render raw database strings through unescaped Blade output in dynamic table cells, including `article/index.blade.php` and `category/index.blade.php`. An authenticated attacker can save malicious input through product creation or category forms. When another user, including a worker or administrator, opens the corresponding product sheet, category listing or dashboard, the stored JavaScript executes in that user's browser context. This can enable cross-user script execution, session theft and administrative takeover. This issue is fixed in version 1.6.4.

Fencer Intel 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.

The maintainers of myTinyWMS/myTinyWMS published their own advisory on GitHub. Reviewed sources take precedence over it.
