Name of the Vulnerable Software and Affected Versions OOPSpam Anti-Spam plugin for WordPress versions through 1.2.53

Description The OOPSpam Anti-Spam plugin for WordPress is susceptible to IP Header Spoofing. The plugin improperly trusts client-controlled forwarded headers, such as CF-Connecting-IP and X-Forwarded-For, without verifying their origin from trusted proxies. This allows attackers to spoof their IP address and circumvent IP-based security measures like blocked IP lists and rate limiting. Attackers can achieve this by sending arbitrary HTTP headers with their requests.

Recommendations Update the OOPSpam Anti-Spam plugin to a version beyond 1.2.53.
