This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

AI Analysis

Impact

The LightSync Pro plugin for WordPress allows authenticated users with Author-level access or higher to upload arbitrary files because the rest_replace_media() function does not validate file types. This flaw corresponds to CWE-434 and could enable an attacker to place malicious scripts on the server, leading to remote code execution.

Affected Systems

LightSync Pro – Connect & Sync Cloud Assets | Lightroom, Canva, Figma, Dropbox & Shutterstock for WordPress. All plugin releases up to and including version 2.1.6 are affected.

Risk and Exploitability

The CVSS score of 8.8 indicates a high severity vulnerability. No EPSS score is available, and the flaw is not listed in CISA’s KEV catalog. Exploitation requires an authenticated session with at least Author privileges and the ability to use the media upload endpoint exposed by the plugin. Once the attacker uploads a malicious file, remote code execution may be achieved on the host server.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the LightSync Pro plugin to the latest release that contains a file type validation fix.
  • If an immediate upgrade is unavailable, block or remove the media upload capability for Author and higher roles, or restrict the plugin’s upload endpoint through server‑side access controls.
  • Add server‑level file type validation or firewall rules that reject uploads of executable or script file types such as .php, .exe, or .js.
