Pypi · Request-Filtering-Agent · CVE-2025-57814
Name of the Vulnerable Software and Affected Versions:
request-filtering-agent versions 1.x.x and earlier
Description:
request-filtering-agent is an http(s).Agent implementation designed to block requests to Private/Reserved IP addresses. HTTPS requests to `127.0.0.1` bypass IP address filtering, while HTTP requests are correctly blocked. This allows potential access to internal HTTPS services running on localhost, bypassing the library’s Server-Side Request Forgery (SSRF) protection. The issue is particularly dangerous when applications accept user-controlled URLs and internal services are protected only by network-level restrictions.
Recommendations:
Upgrade to request-filtering-agent version 2.0.0 or later.
