Summary
Duplicate Advisory: Pingora Request Smuggling and Cache Poisoning
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-93c7-7xqw-w357. This link is maintained to preserve external references.

Original Description

Pingora versions prior to 0.5.0 which used the caching functionality in pingora-proxy did not properly drain the downstream request body on cache hits.

This allows an attacker to craft malicious HTTP/1.1 requests which could lead to request smuggling or cache poisoning.

This flaw was corrected in commit fda3317ec822678564d641e7cf1c9b77ee3759ff by ensuring that the downstream request body is always drained before a connection can be reused.

See the blog post for more information.
