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...

CVE-2026-73495 blaze: Chunked-body trailer fields promoted into Request.headers in blaze-server (front-end header-sanitization bypass)

blaze is a Scala library for building asynchronous pipelines, with a focus on network IO. Prior to 0.23.18 and 1.0.0-M42, blaze-server can merge HTTP/1.1 chunked-body trailer fields into Request.headers. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject...
