Summary

CVE-2026-86771 is a high-severity SSRF (CWE-918) vulnerability in Snipeitapp Snipe-It. Its CVSS base score is 8.3 (High).

Operationally, ranked at the 24th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

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.

Mitigating Controls (NIST 800-53 r5) AI

AC-4 Information Flow Enforcement good match

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

SI-10 Information Input Validation good match

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

SC-7 Boundary Protection partial match

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
blocks

Secure development practices directly include input validation and destination allow-listing that prevent SSRF.

DE.CM-09 partial match
blocks

Runtime monitoring of web applications and services can detect anomalous outbound requests indicative of SSRF.

ID.RA-01 partial match
blocks

Vulnerability identification processes can discover and record SSRF flaws in web applications.

PR.IR-01 partial match
blocks

Network segmentation and egress controls can limit the damage from successful SSRF requests.
