CI4MS Vulnerable to .env CRLF Injection via Unvalidated `host` Parameter in Install Controller

Summary The Install::index controller reads the host POST parameter without any validation and passes it directly into updateEnvSettings, which writes it into the .env file via pregreplace. Because newline characters in the value are not stripped, an attacker can inject arbitrary configuration...

PT-2026-31666

Name of the Vulnerable Software and Affected Versions: basic-ftp versions 5.2.0 Description: basic-ftp is an FTP client for Node.js. Versions prior to 5.2.1 are susceptible to FTP command injection due to improper handling of CRLF sequences r within file path parameters used in high-level path AP...

Vulnerability of the ngx_mail_smtp_module module in NGINX Plus and NGINX Open Source HTTP servers, allowing attackers to compromise the integrity of protected information.

The vulnerability of the ngxmailsmtpmodule module in NGINX Plus and NGINX Open Source servers is related to the failure to take measures to neutralize CRLF sequences. Exploiting this vulnerability can allow a remote attacker to compromise the integrity of the protected information...

Security Bulletin: tCRLF Injection Vulnerability in Netty HttpRequestEncoder Leading to Request Smuggling, affects watsonx.data

Summary Netty versions prior to 4.1.129.Final and 4.2.8.Final are vulnerable to CRLF injection in HttpRequestEncoder, allowing request smuggling if URIs are not properly sanitized. The issue is fixed in versions 4.1.129.Final and 4.2.8.Final. This can affect watsonx.data. Vulnerability Details...

PT-2026-30675

Plunk is an open-source email platform built on top of AWS SES. Prior to 0.8.0, a CRLF header injection vulnerability was discovered in SESService.ts, where user-supplied values for from.name, subject, custom header keys/values, and attachment filenames were interpolated directly into raw MIME...

GHSA-RX22-G9MX-QRHV Rack's improper unfolding of folded multipart headers preserves CRLF in parsed parameter values

Summary Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename or name instead of removing the folded line break during unfolding. As a result,...

CVE-2026-34715

ewe is a Gleam web server. Prior to version 3.0.6, the encodeheaders function in src/ewe/internal/encoder.gleam directly interpolates response header keys and values into raw HTTP bytes without validating or stripping CRLF \r\n sequences. An application that passes user-controlled data into...

UBUNTU-CVE-2026-26962

Rack is a modular Ruby web server interface. From version 3.2.0 to before version 3.2.6, Rack::Multipart::Parser unfolds folded multipart part headers incorrectly. When a multipart header contains an obs-fold sequence, Rack preserves the embedded CRLF in parsed parameter values such as filename o...

CVE-2026-34715

Vulnerability: ewe (Gleam web server) prior to 3.0.6 allows HTTP header injection via encode_headers in src/ewe/internal/encoder.gleam. The function directly interpolates response header keys and values into raw HTTP bytes without validating or stripping CRLF sequences, so user-controlled data (e...

AIOHTTP has CRLF injection through multipart part content type header construction

Summary An attacker who controls the contenttype parameter in aiohttp could use this to inject extra headers or similar exploits. Impact If an application allows untrusted data to be used for the multipart contenttype parameter when constructing a request, an attacker may be able to manipulate th...

CVE-2026-34514

CVE-2026-34514 affects AIOHTTP prior to 3.13.4, where the content_type parameter used when constructing multipart headers could enable CRLF injection leading to extra header insertion. The vulnerability is mitigated by upgrading to 3.13.4, which patches the issue. The CVSS data (MEDIUM, network v...

Important: nodejs22

Issue Overview: Undici allows duplicate HTTP Content-Length headers when they are provided in an array with case-variant names e.g., Content-Length and content-length. This produces malformed HTTP/1.1 requests with multiple conflicting Content-Length values on the wire. Who is impacted:...
