Hi, The following vulnerability was published for busybox. CVE-2026-88829[0]: | A flaw was found in BusyBox httpd's reverse proxy feature. When the | proxy is configured to forward requests matching a URL prefix to a | backend server, only the first HTTP request on a TCP connection has | its path rewritten. An attacker can send a pipelined second request | that is relayed verbatim to the backend, bypassing the configured | path restrictions. This allows accessing arbitrary paths on the | backend server that were not intended to be exposed through the | proxy. https://bugzilla.redhat.com/show_bug.cgi?id=2531343 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
