CVE-2026-86771: Snipeitapp Snipe-It

High severity, CVSS 7.6. EPSS: 0.3% chance of exploitation in the next 30 days.

Snipe-IT versions before 8.7.0 fail to HTML-escape the employee_num field in the acceptance PDF generator, allowing attackers with users.edit permission to inject img tags into TCPDF's writeHTML() function. Attackers can craft a malicious employee_num value containing an img tag with an arbitrary HTTP(S) URL to trigger server-side requests to internal services, cloud metadata endpoints, or external targets when a victim signs an asset acceptance.

Affected products

• Snipeitapp Snipe-It: before 8.7.0 (fixed in 8.7.0)
