GHSA-jhph-5q74-pmfx: snipe/snipe-it (CVE-2026-55466)

Package	Ecosystem	Affected	Fixed in
snipe/snipe-it	Packagist	<8.6.2	8.6.2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Snipe-IT versions before 8.6.2 (Packagist snipe/snipe-it) are vulnerable to stored cross-site scripting through asset attachments. A low-privilege user with asset file upload rights can upload an XHTML document that bypasses the SVG sanitizer, then have it served inline from the application's origin so that injected script runs in other users' browsers, which the source says could be used to reach administrator-level access. Upgrade to version 8.6.2 or later, which is the listed fixed version.
