CVE-2024-0828 in Make Your Blog Posts Accessible with Text to Speech Audio Plugin
Summary
by MITRE • 03/13/2024
The Play.ht – Make Your Blog Posts Accessible With Text to Speech Audio plugin for WordPress is vulnerable to unauthorized access of functionality due to a missing capability check on several functions in all versions up to, and including, 3.6.4. This makes it possible for authenticated attackers, with subscriber access or higher, to delete, retrieve, or modify post metadata, retrieve posts contents of protected posts, modify conversion data and delete article audio.

The CVE-2024-0828 vulnerability affects the Play.ht WordPress plugin, specifically targeting versions up to and including 3.6.4. This security flaw represents a critical authorization bypass issue that undermines the plugin's access control mechanisms. The vulnerability stems from insufficient capability checks within the plugin's codebase, creating a pathway for unauthorized operations that should be restricted to administrators or privileged users. The affected plugin provides text-to-speech functionality for WordPress blog posts, making it a potentially attractive target for attackers seeking to exploit content management systems.
The technical implementation of this vulnerability lies in the absence of proper capability verification within multiple functions exposed by the Play.ht plugin. Attackers with subscriber-level privileges or higher can leverage this weakness to perform operations that normally require administrator-level permissions. The flaw specifically impacts post metadata management, allowing unauthorized modification or deletion of critical post information. Additionally, the vulnerability enables attackers to access protected post content that should remain hidden from less privileged users. The plugin's conversion data handling and audio file management functions also fall victim to this authorization bypass, creating multiple attack vectors within the same vulnerable codebase.
The operational impact of this vulnerability extends beyond simple data access, as it enables comprehensive content manipulation capabilities. Attackers can not only retrieve sensitive information from protected posts but also modify conversion data that affects how content is processed and delivered. The ability to delete article audio files represents a significant threat to content integrity and availability. This vulnerability essentially allows authenticated attackers to perform administrative functions within the plugin's scope, potentially leading to data corruption, content theft, or service disruption. The implications are particularly severe in environments where the plugin is used to manage sensitive or proprietary content.
Security professionals should address this vulnerability through immediate plugin updates to versions that implement proper capability checks and authorization controls. The remediation process requires verifying that all functions within the Play.ht plugin properly validate user capabilities before executing privileged operations. Organizations should implement network segmentation and monitoring to detect unauthorized access attempts to the plugin's endpoints. The vulnerability aligns with CWE-284, which addresses improper access control, and maps to ATT&CK technique T1078 for valid accounts and privilege escalation. Regular security audits of WordPress plugins and their capability checks are essential to prevent similar authorization bypass vulnerabilities from compromising system integrity.
