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-2026-619 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-2026-55603

http-proxy-middleware is node.js http-proxy middleware. From 3.0.4 until 3.0.7 and 4.1.1, fixRequestBody is the library's documented helper for re-emitting a request body that was already consumed by a body parser. When the outgoing Content-Type is multipart/form-data, it rebuilds the body with...

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. However, if a server does not support non-synchronizing...

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

Summary of CVE-2026-47240 (Net::IMAP, Ruby) : The vulnerability affects Net::IMAP’s IMAP client in Ruby, where several commands accept a “raw data” argument that is validated but could still be exploited if a server does not support non-synchronizing literals. In that case, a server may interpret...

CVE-2026-47240 Net::IMAP: Command Injection via non-synchronizing literal in "raw" argument

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. However, if a server does not support non-synchronizing...

CVE-2026-47241

Net::IMAP in Ruby (affected: before 0.6.5 and 0.5.15) validates CRLF but may send a user-controlled raw string verbatim, allowing a subsequent command to be absorbed as a continuation of the first. This can cause the first command to fail and block further responses until another command is issue...
