The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-25155 is an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability, classified as CWE-22, in the efreja Music Sheet Viewer WordPress plugin (music-sheet-viewer). This flaw enables path traversal attacks and affects all versions of the plugin up to and including 4.1.

The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high severity due to network accessibility, low complexity, no required privileges or user interaction, and unchanged scope. Unauthenticated remote attackers can exploit it to achieve high-impact confidentiality violations by reading arbitrary files on the affected server.

Mitigation guidance is available in the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/music-sheet-viewer/vulnerability/wordpress-music-sheet-viewer-plugin-4-1-arbitrary-file-read-vulnerability?_s_id=cve, which details the arbitrary file read vulnerability in Music Sheet Viewer plugin version 4.1.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
attack.mitre.org →
T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
attack.mitre.org →
Why these techniques?

The path traversal vulnerability in the public-facing WordPress plugin enables unauthenticated remote exploitation of the application to read arbitrary server files, directly mapping to T1190 (Exploit Public-Facing Application) for initial access and T1005 (Data from Local System) for collection of sensitive data from the local filesystem.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates CVE-2025-25155 by identifying, reporting, and correcting the path traversal flaw in Music Sheet Viewer versions <=4.1 through patching.

SI-10 Information Input Validation good match
prevent

Enforces input validation on pathname parameters to the WordPress plugin, blocking path traversal attempts to arbitrary files.

AC-3 Access Enforcement partial match
prevent

Requires enforcement of access controls that limit file reads to authorized directories, addressing unauthorized arbitrary file access via path traversal.
