JLSEC-2026-623 Insufficient HTTP/2 pseudo-header and Host/:authority validation in HTTP.jl server

Description The HTTP/2 server's request validator passed only :method, :path, and :authority through a normalizer that rejects CR/LF/CTL but permits SP/HTAB and applies no host or token grammar. As a result a :method such as "GET /admin?x=" was accepted, :path could carry interior whitespace, and...

JLSEC-2026-616 HTTP/1 client request smuggling via CR/LF in method, target, or host in HTTP.jl

Description The HTTP/1 client serialized request.method and request.target and, in forward-proxy absolute-form, the host verbatim onto the wire with no CR/LF/CTL filtering; the only target validator was wired solely into the server parse path. A caller passing an attacker-influenced URL or method...

JLSEC-2026-618 HTTP/1 request smuggling via bare-LF, lenient chunk size, and TE/CL handling in HTTP.jl server

Description The HTTP/1 server request parser had three framing primitives that could make HTTP.jl disagree with a fronting proxy about message boundaries on a reused keep-alive connection. 1 readlinecrlf tolerated a bare LF on its buffered fast path but required CRLF on the slow path, so the...
