Atheos is a self-hosted browser-based cloud IDE. Prior to v602, similar to GHSA-rgjm-6p59-537v/CVE-2025-22152, the `$target` parameter in `/controller.php` was not properly validated, which could allow an attacker to execute arbitrary files on the server via path traversal. v602 contains a fix for the issue.

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.
