CVE-2026-55766

Summary (CVE-2026-55766): guzzlehttp/psr7 (PHP) before 2.12.1 is vulnerable to CRLF injection in the HTTP start-line fields (method, protocol version, reason phrase) when attacker-controlled data ends up in those fields and the message is serialized or forwarded. The flaw requires the malformed m...

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...

JLSEC-2026-619 CR/LF injection in server-sent events (SSE) fields in HTTP.jl

Description The server-side SSE serializer wrote the single-line fields event, id, and retry verbatim to the text/event-stream wire with no CR/LF filtering, and split the multi-line data field only on \n, ignoring a bare \r that is also a valid SSE line terminator. The SSEEvent constructor...

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...

CVE-2026-47241

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to 0.6.5 and 0.5.15, several Net::IMAP commands accept a raw string argument which is only validated to prevent CRLF injection and then sent verbatim. If this string is derived from user-controlled inpu...

CVE-2026-47242

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to 0.6.5 and 0.5.15, when Net::IMAPid is called with a hash argument, although the ID field value strings are correctly quoted escaping quoted specials, they were not validated to prohibit CRLF sequence...

CVE-2026-47240

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. Prior to 0.6.5 and 0.5.15, several Net::IMAP commands accept a "raw data" argument that is sent verbatim after validation to prevent command injection.
