Summary

CVE-2025-49466 is a medium-severity Relative Path Traversal (CWE-23) vulnerability in Sr (inferred from references). Its CVSS base score is 5.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 48th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Explicit validation of path inputs stops .. sequences from ever being interpreted by the file system.

AC-3 Access Enforcement partial match

Access enforcement directly blocks unauthorized file reads/writes that result from unresolved .. sequences.

AC-4 Information Flow Enforcement partial match

Information-flow rules can be configured to reject traversals that would move data outside an approved directory boundary.

AC-6 Least Privilege partial match

Least privilege reduces the set of reachable files even when a traversal succeeds.

SA-8 Security and Privacy Engineering Principles partial match

Secure-engineering principles require safe pathname construction and input neutralization before any file operation.

PR.PS-06 mostly match
blocks

Secure SDLC practices directly require input validation and path sanitization that prevent relative traversal.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.

A.8.28 Secure coding partial match
prevents

Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.
