Published: 29 August 2024
Summary
CVE-2024-7856 is a high-severity Missing Authorization (CWE-862) vulnerability in Sonaar Mp3 Audio Player For Music\, Radio \& Podcast. Its CVSS base score is 8.1 (High).
Operationally, ranked in the top 1.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The MP3 Audio Player – Music Player, Podcast Player & Radio by Sonaar plugin for WordPress is affected by an arbitrary file deletion vulnerability in all versions through 5.7.0.1. The flaw stems from a missing capability check on the removeTempFiles() function combined with insufficient validation of the file parameter, allowing unauthorized file operations as described under CWE-862. The issue carries a CVSS 3.1 score of 8.1 with network attack vector and low complexity.
Authenticated users holding subscriber-level privileges or higher can exploit the weakness to delete arbitrary files on the server. Successful exploitation can lead to remote code execution, particularly when critical files such as wp-config.php are removed, resulting in integrity and availability impacts without requiring user interaction.
A fix addressing the missing authorization and path validation is referenced in the plugin's changeset for class-sonaar-music.php, with corresponding code locations documented in the affected 5.7.0.1 tag. The current EPSS score of 0.7632, with a peak of 0.7695, indicates sustained exploitation interest following disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
