CyberRota Analysis

AI-Generated

The vulnerability affects Catalyst::Plugin::Static::Simple versions up to 0.38 for Perl, where the _serve_static method improperly sets the Cache-Control header to "public," allowing sensitive content to be cached and potentially exposed to unauthorized users. This misconfiguration can lead to the unintended disclosure of private data, especially in scenarios where requests include an Authorization header. Organizations using this plugin should prioritize remediation to prevent potential data leaks and ensure proper access controls.

Original NVD Description

Catalyst::Plugin::Static::Simple versions through 0.38 for Perl mark responses as publicly cacheable. The _serve_static method always sets the Cache-Control header to "public", with no means of overriding it. This advises proxies that the content may be stored in a shared cache, and may be reused in responses to requests from other users. (This includes requests with an Authorization header.) Configuring the expires time to "0" to disable caching, as documented, is ignored.
