VectorAV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:L/SC:H/SI:N/SA:L
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.
