CVE-2026-33604

A flaw was found in Dovecot. A remote attacker can exploit this by crafting a message with a specific line ending. If Dovecot relays this message, it can bypass security protections, allowing the attacker to inject spoofed email into a vulnerable downstream mail server. This vulnerability is...

CVE-2026-33604

An attacker that can get Dovecot to relay a message, for example through Sieve redirect or submission relay, can use a crafted line ending in the message body to bypass the outbound protection that prevents message content from being interpreted as SMTP commands. A downstream mail server that...

Astra Linux – Vulnerability in pillow

A issue was discovered in Pillow prior to version 8.2.0. For EPS data, the readline implementation used in EPSImageFile has to handle any combination of \r and \n as line endings. This implementation uses a quadratic method of accumulating lines while searching for a line ending. A malicious EPS...

GHSA-8C48-Q9WJ-3W37 rclone: FTP Command Arguments Permit CRLF Injection When Custom Encoding Preserves Newlines

Summary A valid but nondefault FTP filename encoding can restore raw CR/LF immediately before an attacker-controlled path is interpolated into the line-oriented FTP control channel. The dependency does not reject CR or LF in command arguments, so a filename can inject an independent...

CVE-2026-47736

Summary: CVE-2026-47736 affects the Puma Ruby/Rack web server when PROXY protocol v1 is enabled. In affected releases (5.5.0 up to 7.2.1 and 8.0.2), Puma reads incoming bytes into an internal buffer while waiting for CRLF to detect a PROXY v1 line, allowing an attacker to send data without CRLF a...

aiosmtplib vulnerable to SMTP command injection via CR/LF in sender/recipient address

Summary aiosmtplib's SMTP.mail, SMTP.rcpt, SMTP.vrfy and SMTP.expn send the caller-supplied email address to the server without rejecting embedded CR/LF \r\n bytes. An address that contains a CR/LF is written verbatim onto the SMTP control connection, so the bytes after the CRLF are framed by the...

CVE-2026-49756 Multipart form-data header injection in Req via unescaped name/filename/content_type

Improper Neutralization of CRLF Sequences 'CRLF Injection' vulnerability in wojtekmach Req allows multipart parameter smuggling via attacker-influenced part metadata. Req.Utils.encodeformpart/2 in lib/req/utils.ex builds the per-part headers by interpolating the caller-supplied name, filename, an...

CVE-2026-48861

Improper Neutralization of CRLF Sequences 'CRLF Injection' vulnerability in elixir-mint Mint allows HTTP Request Splitting and HTTP Request Smuggling. In lib/mint/http1/request.ex, the encoderequestline/2 function splices the caller-supplied method and target arguments directly into the HTTP/1...

CVE-2026-47072

Improper Neutralization of CRLF Sequences 'CRLF Injection' vulnerability in benoitc hackney allows HTTP Request/Response Splitting. The WebSocket upgrade code in src/hackneyws.erl copies the host, path, headers ExtraHeaders, and protocols options from the caller-supplied opts map into the interna...

UBUNTU-CVE-2026-7010

HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP request lines or control field header values. The unvalidated inputs are the method and URI in the request line, the URL host that becomes the Host: header, and HTTP/1.1 control data field values. An attacker who controls one ...

GHSA-HV23-4QP7-8C8R ninenines cowlib: Improper Neutralization of CRLF Sequences ('CRLF Injection') vulnerability allows SSE event splitting and injection via unvalidated field values

Improper Neutralization of CRLF Sequences 'CRLF Injection' vulnerability in ninenines cowlib allows SSE event splitting and injection via unvalidated field values. cowsse:event/1 in cowlib guards the id and event fields against \n but not against bare \r, and the internal prefixlines/2 function...

CRLF Injection

Net::IMAP is vulnerable to CRLF Injection. The vulnerability is due to insufficient validation and escaping of raw string arguments passed to several IMAP commands, which allows an attacker to inject CRLF sequences and execute arbitrary IMAP commands by supplying crafted user-controlled input...

CRLF Injection

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to CRLF Injection via the upgrade option of the client.request function. An attacker can inject malicious data into HTTP headers or prematurely terminate HTTP requests by...
