Summary
Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, a collection that allows downloadable SVG uploads can store a malicious SVG that bypasses sanitization and executes attacker-controlled JavaScript when a user downloads and opens the SVG. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

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