Summary

CVE-2026-46345 is a high-severity Path Traversal (CWE-22) vulnerability. Its CVSS base score is 8.4 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 5th 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 AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

compliance-trestle is a tooling platform for managing compliance as code. Prior to versions 3.12.2 and 4.0.3, the `-o/--output` argument in `trestle author jinja` allows writing files outside the intended workspace. The application does not properly validate, `../`, `..\`, or absolute…

Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.AA-05 partial match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.PS-06 partial match
prevents

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

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

finds

Security testing in development catches path traversal via static/dynamic analysis.

mitigates

Information access restriction limits which files an application may read or write.
