Apache2 - Transfer-Encoding Chunked XSS

Apache2 PHP before 5.6.38, 7.0.x before 7.0.32, 7.1.x before 7.1.22, and 7.2.x before 7.2.10 contain a reflected cross-site scripting vulnerability caused by mishandling of chunked transfer-encoding requests in sapi/apache2handler/sapiapache2.c. Attackers can execute malicious scripts via crafted...

undertow-core: Undertow:HTTP request smuggling via oversized chunk-size bit overlap

A flaw was found in the ChunkReader component of the Undertow HTTP server, which is used by WildFly and JBoss EAP to handle chunked transfer encoding. The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially...

UBUNTU-CVE-2026-93573

A flaw was found in Netty's HTTP/1.1 decoder. This vulnerability allows a remote attacker to bypass Transfer-Encoding header validation by splitting the Transfer-Encoding field across multiple headers, with the last field containing a non-final transfer coding like gzip or deflate. This bypass ca...
