There are no known exploits in the wild at this time. The vulnerability is classified under CWE-94 (Improper Control of Generation of Code).
AI Analysis
Technical Summary
The Custom css-js-php WordPress plugin through version 2.0.7 does not properly sanitize user input before incorporating it into a SQL query. The output of this query is then passed to the PHP eval() function, which executes the content as code. This improper control of code generation (CWE-94) enables unauthenticated attackers to execute arbitrary PHP code on the server, potentially leading to full compromise of the affected system. No CVSS score or vendor advisory is available, and no patch or official remediation has been published.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary PHP code on the server hosting the vulnerable plugin. This can lead to complete server compromise, data theft, or further malicious activities. However, no known exploits have been reported in the wild, and the patch status is currently unconfirmed.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider disabling or removing the vulnerable plugin to prevent exploitation. Avoid exposing the affected plugin to untrusted users or the public internet.
