The AI Engine WordPress plugin before 3.7.2 does not confine a caller-supplied URL when mapping it to a local filesystem path before reading the file and forwarding its contents to an external service, allowing users with a subscriber-level account to read arbitrary files from the server and exfiltrate them off-host. Reaching the issue at subscriber level requires a non-default public API feature to be enabled; otherwise the same issue is reachable by an administrator, which on multisite allows a non-super subsite administrator to read the network-shared configuration and its secrets.
The AI Engine plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.9.4. The simpleTranscribeAudio endpoint fails to restrict URL schemes before calling getaudio(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to read any file on the web server and exfiltrate it via the plugin’s OpenAI API integration.
AI Engine < 2.4.3 is susceptible to remote-code-execution (RCE) via Log Poisoning. The AI Engine WordPress plugin before 2.5.1 fails to validate the file extension of "logspath", allowing Administrators to change log filetypes from .log to .php.
The AI Engine WordPress plugin before 1.6.83 does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example, in multisite setup).
