| CVE-2026-34975 | 1 Useplunk | 1 Plunk | 2026-04-22 | 8.5 High |
| 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 messages without sanitization. An authenticated API user could inject arbitrary email headers (e.g. Bcc, Reply-To) by embedding carriage return/line feed characters in these fields, enabling silent email forwarding, reply redirection, or sender spoofing. The fix adds input validation at the schema level to reject any of these fields containing \r or \n characters, consistent with the existing validation already applied to the contentId field. This vulnerability is fixed in 0.8.0. | ||||
| CVE-2026-32964 | 1 Silextechnology | 3 Amc Manager, Sd-330ac, Sd-330ac Firmware | 2026-04-22 | 6.5 Medium |
| SD-330AC and AMC Manager provided by silex technology, Inc. contain an improper neutralization of CRLF sequences ('CRLF Injection') vulnerability. Processing some crafted configuration data may lead to arbitrary entries injected to the system configuration. | ||||
| CVE-2026-2400 | 1 Schneider-electric | 1 Powerchute Serial Shutdown | 2026-04-22 | 4.3 Medium |
| CWE-93 Improper Neutralization of CRLF Sequences ('CRLF Injection') vulnerability exists that could cause application user credentials to reset when a Web Admin user alters the POST /setPCBEDesc request payload. | ||||
| CVE-2026-39983 | 1 Patrickjuchli | 1 Basic-ftp | 2026-04-21 | 8.6 High |
| basic-ftp is an FTP client for Node.js. Prior to 5.2.1, basic-ftp allows FTP command injection via CRLF sequences (\r\n) in file path parameters passed to high-level path APIs such as cd(), remove(), rename(), uploadFrom(), downloadTo(), list(), and removeDir(). The library's protectWhitespace() helper only handles leading spaces and returns other paths unchanged, while FtpContext.send() writes the resulting command string directly to the control socket with \r\n appended. This lets attacker-controlled path strings split one intended FTP command into multiple commands. This vulnerability is fixed in 5.2.1. | ||||
| CVE-2026-1502 | 1 Python | 1 Cpython | 2026-04-21 | 4.5 Medium |
| CR/LF bytes were not rejected by HTTP client proxy tunnel headers or host. | ||||
| CVE-2026-26962 | 1 Rack | 1 Rack | 2026-04-21 | 4.8 Medium |
| 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 or name instead of removing the folded line break during unfolding. As a result, applications that later reuse those parsed values in HTTP response headers may be vulnerable to downstream header injection or response splitting. This issue has been patched in version 3.2.6. | ||||
| CVE-2025-5020 | 1 Mozilla | 1 Firefox | 2026-04-20 | 4.3 Medium |
| Opening maliciously-crafted URLs in Firefox from other apps such as Safari could have allowed attackers to spoof website addresses if the URLs utilized non-HTTP schemes used internally by the Firefox iOS client. This vulnerability was fixed in Firefox for iOS 139. | ||||
| CVE-2026-21428 | 1 Yhirose | 1 Cpp-httplib | 2026-04-18 | 7.5 High |
| cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to version 0.30.0, the ``write_headers`` function does not check for CR & LF characters in user supplied headers, allowing untrusted header value to escape header lines. This vulnerability allows attackers to add extra headers, modify request body unexpectedly & trigger an SSRF attack. When combined with a server that supports http1.1 pipelining (springboot, python twisted etc), this can be used for server side request forgery (SSRF). Version 0.30.0 fixes this issue. | ||||
| CVE-2026-23829 | 1 Axllent | 1 Mailpit | 2026-04-18 | 5.3 Medium |
| Mailpit is an email testing tool and API for developers. Prior to version 1.28.3, Mailpit's SMTP server is vulnerable to Header Injection due to an insufficient Regular Expression used to validate `RCPT TO` and `MAIL FROM` addresses. An attacker can inject arbitrary SMTP headers (or corrupt existing ones) by including carriage return characters (`\r`) in the email address. This header injection occurs because the regex intended to filter control characters fails to exclude `\r` and `\n` when used inside a character class. Version 1.28.3 fixes this issue. | ||||
| CVE-2026-22777 | 1 Comfy | 2 Comfyui, Comfyui-manager | 2026-04-18 | 7.5 High |
| ComfyUI-Manager is an extension designed to enhance the usability of ComfyUI. Prior to versions 3.39.2 and 4.0.5, an attacker can inject special characters into HTTP query parameters to add arbitrary configuration values to the config.ini file. This can lead to security setting tampering or modification of application behavior. This issue has been patched in versions 3.39.2 and 4.0.5. | ||||
| CVE-2026-24489 | 1 Happyhackingspace | 1 Gakido | 2026-04-18 | 5.3 Medium |
| Gakido is a Python HTTP client focused on browser impersonation and anti-bot evasion. A vulnerability was discovered in Gakido prior to version 0.1.1 that allowed HTTP header injection through CRLF (Carriage Return Line Feed) sequences in user-supplied header values and names. When making HTTP requests with user-controlled header values containing `\r\n` (CRLF), `\n` (LF), or `\x00` (null byte) characters, an attacker could inject arbitrary HTTP headers into the request. The fix in version 0.1.1 adds a `_sanitize_header()` function that strips `\r`, `\n`, and `\x00` characters from both header names and values before they are included in HTTP requests. | ||||
| CVE-2026-1046 | 1 Mattermost | 2 Mattermost, Mattermost Desktop | 2026-04-18 | 7.6 High |
| Mattermost Desktop App versions <=6.0 6.2.0 5.2.13.0 fail to validate help links which allows a malicious Mattermost server to execute arbitrary executables on a user’s system via the user clicking on certain items in the Help menu Mattermost Advisory ID: MMSA-2026-00577 | ||||
| CVE-2026-23953 | 2 Linuxcontainers, Lxc | 2 Incus, Incus | 2026-04-18 | 8.7 High |
| Incus is a system container and virtual machine manager. In versions 6.20.0 and below, a user with the ability to launch a container with a custom YAML configuration (e.g a member of the ‘incus’ group) can create an environment variable containing newlines, which can be used to add additional configuration items in the container’s lxc.conf due to newline injection. This can allow adding arbitrary lifecycle hooks, ultimately resulting in arbitrary command execution on the host. Exploiting this issue on IncusOS requires a slight modification of the payload to change to a different writable directory for the validation step (e.g /tmp). This can be confirmed with a second container with /tmp mounted from the host (A privileged action for validation only). A fix is planned for versions 6.0.6 and 6.21.0, but they have not been released at the time of publication. | ||||
| CVE-2026-1536 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-04-18 | 5.8 Medium |
| A flaw was found in libsoup. An attacker who can control the input for the Content-Disposition header can inject CRLF (Carriage Return Line Feed) sequences into the header value. These sequences are then interpreted verbatim when the HTTP request or response is constructed, allowing arbitrary HTTP headers to be injected. This vulnerability can lead to HTTP header injection or HTTP response splitting without requiring authentication or user interaction. | ||||
| CVE-2026-35601 | 2 Go-vikunja, Vikunja | 2 Vikunja, Vikunja | 2026-04-17 | 4.1 Medium |
| Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the CalDAV output generator builds iCalendar VTODO entries via raw string concatenation without applying RFC 5545 TEXT value escaping. User-controlled task titles containing CRLF characters break the iCalendar property boundary, allowing injection of arbitrary iCalendar properties such as ATTACH, VALARM, or ORGANIZER. This vulnerability is fixed in 2.3.0. | ||||
| CVE-2026-35515 | 1 Nestjs | 1 Nest | 2026-04-17 | 6.1 Medium |
| Nest is a framework for building scalable Node.js server-side applications. Prior to 11.1.18, SseStream._transform() interpolates message.type and message.id directly into Server-Sent Events text protocol output without sanitizing newline characters (\r, \n). Since the SSE protocol treats both \r and \n as field delimiters and \n\n as event boundaries, an attacker who can influence these fields through upstream data sources can inject arbitrary SSE events, spoof event types, and corrupt reconnection state. This vulnerability is fixed in 11.1.18. | ||||
| CVE-2026-6351 | 1 Openfind | 2 Mailaudit, Mailgates | 2026-04-17 | 7.5 High |
| MailGates/MailAudit developed by Openfind has a CRLF Injection vulnerability, allowing unauthenticated remote attackers to exploit this vulnerability to read system files. | ||||
| CVE-2026-28296 | 1 Redhat | 1 Enterprise Linux | 2026-04-17 | 4.3 Medium |
| A flaw was found in the FTP GVfs backend. A remote attacker could exploit this input validation vulnerability by supplying specially crafted file paths containing carriage return and line feed (CRLF) sequences. These unsanitized sequences allow the attacker to terminate intended FTP commands and inject arbitrary FTP commands, potentially leading to arbitrary code execution or other severe impacts. | ||||
| CVE-2026-29046 | 2 Maximmasiutin, Ritlabs | 2 Tinyweb, Tinyweb | 2026-04-17 | 8.2 High |
| TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. Prior to version 2.04, TinyWeb accepts request header values and later maps them into CGI environment variables (HTTP_*). The parser did not strictly reject dangerous control characters in header lines and header values, including CR, LF, and NUL, and did not consistently defend against encoded forms such as %0d, %0a, and %00. This can enable header value confusion across parser boundaries and may create unsafe data in the CGI execution context. This issue has been patched in version 2.04. | ||||
| CVE-2026-3634 | 3 Gnome, Libsoup, Redhat | 3 Libsoup, Libsoup, Enterprise Linux | 2026-04-17 | 3.9 Low |
| A flaw was found in libsoup. An attacker controlling the value used to set the Content-Type header can inject a Carriage Return Line Feed (CRLF) sequence due to improper input sanitization in the `soup_message_headers_set_content_type()` function. This vulnerability allows for the injection of arbitrary header-value pairs, potentially leading to HTTP header injection and response splitting attacks. | ||||
