Published:September 08, 2026
Updated:September 22, 2026
Snipe-IT versions before 8.7.0 contain a CSS injection vulnerability in the Custom CSS field due to incomplete sanitization that reverses HTML encoding on greater-than and double-quote characters. Superusers can plant malicious CSS payloads using @import and url() references to exfiltrate CSRF tokens from other superusers via attribute-selector rules, enabling account takeover.
