Technical Analysis

CVE-2026-81402 is a vulnerability in the DS Ad Rotator WordPress plugin up to version 0.8. The plugin's image upload handler does not perform any capability checks, nonce verification, or file-type validation, enabling unauthenticated attackers to upload arbitrary files, including PHP scripts, to a web-accessible directory. This flaw can be exploited to achieve remote code execution on the hosting server.

Potential Impact

An attacker can upload malicious files, such as PHP scripts, without authentication, leading to potential remote code execution. This compromises the confidentiality, integrity, and availability of the affected system.

Mitigation Recommendations

No official patch or remediation is currently documented. Users should avoid using affected versions (0 through 0.8) of the DS Ad Rotator plugin until a fix is released. Monitor the vendor or plugin repository for updates and apply patches promptly once available.
