Server-Side Request Forgery (SSRF) vulnerability in Joe Hoyle WPThumb allows Server Side Request Forgery. This issue affects WPThumb: from n/a through 0.10.
AnalysisAI
Server-Side Request Forgery (SSRF) in WPThumb plugin for WordPress up to version 0.10 allows authenticated attackers with low privileges to make the server send crafted requests to internal or external resources, potentially leading to limited information disclosure or low-impact manipulation. No public exploit or active exploitation has been identified, and EPSS score is low (0.04%).
Technical ContextAI
WPThumb is a WordPress plugin for dynamic image thumbnail generation. The vulnerability is a Server-Side Request Forgery (SSRF) classified under CWE-918, which occurs when the plugin processes user-supplied URLs without proper validation, allowing an attacker to force the server to make requests to arbitrary destinations. The CVSS vector indicates a network attack vector with high complexity, low privileges required, and user interaction not needed, but scope change suggests the attack can affect resources beyond the vulnerable component.
RemediationAI
Upgrade WPThumb to version 0.11 or later, as the vulnerability is fixed in that release. No workarounds are documented; however, as a compensating control, restrict outbound network requests from the WordPress server via firewall or web application firewall (WAF) rules to limit SSRF impact. Note that blocking all outbound requests may break legitimate plugin functionality.
