Summary

CVE-2026-2251 is a critical-severity Path Traversal (CWE-22) vulnerability in Xerox Freeflow Core. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 30.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-3 (Access Enforcement) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-2251 is an improper limitation of a pathname to a restricted directory vulnerability, classified under CWE-22 as path traversal, affecting Xerox FreeFlow Core. This flaw enables unauthorized path traversal that leads to remote code execution (RCE). The vulnerability impacts versions up to and including 8.0.7, with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to high confidentiality, integrity, and availability impacts.

An unauthenticated attacker with network access can exploit this vulnerability with low complexity and no user interaction required. Successful exploitation allows the attacker to traverse restricted directories and execute arbitrary code on the affected system, potentially leading to full compromise of the Xerox FreeFlow Core instance.

Xerox's security bulletin (Xerox-Security-Bulletin-026-005) and advisory recommend upgrading to FreeFlow Core version 8.1.0, available for download at https://www.support.xerox.com/en-us/product/core/downloads.
