Description
The WP-SOS-Donate Donation Sidebar Plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the `$_SERVER['PHP_SELF']` parameter in all versions up to, and including, 0.9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

AI Analysis

Impact

The WP‑SOS‑Donate Donation Sidebar Plugin does not sanitize the value of $_SERVER['PHP_SELF'] before outputting it. This omission allows an unauthenticated attacker to inject arbitrary JavaScript into pages that are then executed if a user follows a crafted link or performs a similar action. The vulnerability exists in all versions up to and including 0.9.2.

Affected Systems

All installations of switch2mac’s WP‑SOS‑Donate Donation Sidebar Plugin through version 0.9.2 are affected. Any WordPress site that has deployed these plugin versions is vulnerable, as the admin options page outputs the unsanitized server variable.

Risk and Exploitability

The CVSS score of 6.1 indicates moderate severity, while the EPSS score of less than 1 % reflects a low likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog. Because the flaw requires a victim to interact with a link containing the malicious payload, it can be delivered via phishing or similar social engineering. The impact is limited to the victim’s browser, but the overall risk remains moderate due to the need for user interaction.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade to WP‑SOS‑Donate plugin release 0.9.3 or newer, which removes the vulnerability.
  • If an upgrade is not immediately possible, edit the plugin’s options file to escape the $_SERVER['PHP_SELF'] value with esc_url() or htmlspecialchars() before outputting it.
  • Deploy a site‑wide Content Security Policy or use a security plugin to block inline script execution as a defensive measure.
