CVE-2026-77802 is a medium severity vulnerability in Progress® Telerik® Fiddler® Classic for Windows prior to version 6.0.20262.10021. It involves HTTP request smuggling due to inconsistent handling of multiple conflicting Content-Length headers in the proxy request forwarding component. A local attacker with low privileges can exploit this to smuggle additional requests against certain non-compliant origin servers, potentially poisoning responses delivered to other users. The vulnerability arises because Fiddler forwards requests verbatim but frames the body using only the first Content-Length header, causing desynchronization. This can lead to response poisoning and unauthorized access to responses intended for other users. Join the discussion | CVE Database V5 | 10/05/2026, 12:38:58 UTC Added: 10/05/2026, 13:04:17 UTC |
