What is CVE-2026-86738?

Snipe-IT versions prior to 8.7.0 are susceptible to a CSS injection flaw within the Custom CSS field, resulting from insufficient sanitization. This issue allows superusers to inject malicious CSS payloads using @import and url() directives. Consequently, it poses a risk of exfiltrating CSRF tokens from other superusers via specific attribute-selector rules, potentially leading to unauthorized account access.
