Summary
Cross-site scripting in snipe/snipe-it (CVE-2026-55464). Risk of unauthorized operations or information disclosure. Exploitable via assets.edit. Mitigation: upgrade to 8.6.2 or later.
Original description
The description as published by the source.
Impact
CommonMark is configured with html_input => 'escape', which blocks raw HTML injection. However, javascript: URIs in Markdown hyperlinks are not sanitized. A user with assets.edit permission can inject a malicious link into any markdown-textarea custom field. Any user who opens the asset detail page and clicks the link executes arbitrary JavaScript in their browser session.
