Summary

The Music Sheet Viewer plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 4.1 via the read_score_file() function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. CVE-2025-25155 is likely a duplicate of this issue.
