{"id":"CVE-2026-86771","summary":"Snipe-IT before 8.7.0 Server-Side Request Forgery via employee_num","details":"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.","aliases":["GHSA-73xg-j94v-gjcf"],"modified":"2026-09-11T03:48:39.848626329Z","published":"2026-09-09T13:32:27.929Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86771.json","cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86771.json"},{"type":"ADVISORY","url":"https://github.com/grokability/snipe-it/security/advisories/GHSA-73xg-j94v-gjcf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86771"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/snipe-it-before-8.7.0-server-side-request-forgery-via-employee-num"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/grokability/snipe-it","events":[{"introduced":"cfd1ff8413e478a8daab700c15e96c96f93220e2"},{"fixed":"1d05a7ce11e6bf9448c067ac3ffbe5e63882888e"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"8.6.3"},{"fixed":"8.7.0"},{"introduced":"0"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-86771.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:N/VA:L/SC:H/SI:N/SA:L"}]}
