Description
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via SVG File uploads in all versions up to, and including, 3.3.12 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the SVG file.

AI Analysis

Impact

The vulnerability allows an authenticated user with Author or higher privileges to upload an SVG file that contains malicious scripts. Because the Download Manager plugin fails to sanitize or escape the SVG content, the scripts are stored and executed whenever the file is rendered, resulting in arbitrary client‑side code execution.

Affected Systems

The WordPress plugin Download Manager, developed by codename065, is affected in all releases up to and including version 3.3.12.

Risk and Exploitability

The CVSS score of 5.4 indicates moderate severity, while the EPSS score of less than 1% suggests a very low likelihood of exploitation. The vulnerability is not listed in CISA KEV. Exploitation requires the attacker to authenticate with Author‑level or higher access, upload a crafted SVG file, and rely on the script executing in other users’ browsers when they open the file via the plugin’s file upload interface.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Download Manager to version 3.3.13 or later to remove the stored XSS flaw.
  • If an immediate upgrade is not possible, disable SVG uploads entirely or enforce a strict MIME type whitelist that excludes SVG files from being stored.
  • Deploy a Content‑Security‑Policy that blocks inline scripts and restricts script sources to trusted origins to mitigate any residual XSS risk.
