| CVE-2026-3634 | 2 Gnome, Redhat | 2 Libsoup, Enterprise Linux | 2026-03-19 | N/A | 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. | |||||
| CVE-2026-29046 | 1 Ritlabs | 1 Tinyweb | 2026-03-16 | N/A | 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-2026-3848 | 2026-03-12 | N/A | 5.0 MEDIUM | ||
| GitLab has remediated an issue in GitLab CE/EE affecting all versions from 8.11 before 18.7.6, 18.8 before 18.8.6, and 18.9 before 18.9.2 that could have allowed an authenticated user to make unintended internal requests through proxy environments under certain conditions due to improper input validation in import functionality. | |||||
| CVE-2026-3234 | 2026-03-12 | N/A | 4.3 MEDIUM | ||
| A flaw was found in mod_proxy_cluster. This vulnerability, a Carriage Return Line Feed (CRLF) injection in the decodeenc() function, allows a remote attacker to bypass input validation. By injecting CRLF sequences into the cluster configuration, an attacker can corrupt the response body of INFO endpoint responses. Exploitation requires network access to the MCMP protocol port, but no authentication is needed. | |||||
| CVE-2026-30227 | 1 Jstedfast | 1 Mimekit | 2026-03-12 | N/A | 5.3 MEDIUM |
| MimeKit is a C# library which may be used for the creation and parsing of messages using the Multipurpose Internet Mail Extension (MIME), as defined by numerous IETF specifications. Prior to version 4.15.1, a CRLF injection vulnerability in MimeKit allows an attacker to embed \r\n into the SMTP envelope address local-part (when the local-part is a quoted-string). This is non-compliant with RFC 5321 and can result in SMTP command injection (e.g., injecting additional RCPT TO / DATA / RSET commands) and/or mail header injection, depending on how the application uses MailKit/MimeKit to construct and send messages. The issue becomes exploitable when the attacker can influence a MailboxAddress (MAIL FROM / RCPT TO) value that is later serialized to an SMTP session. RFC 5321 explicitly defines the SMTP mailbox local-part grammar and does not permit CR (13) or LF (10) inside Quoted-string (qtextSMTP and quoted-pairSMTP ranges exclude control characters). SMTP commands are terminated by <CRLF>, making CRLF injection in command arguments particularly dangerous. This issue has been patched in version 4.15.1. | |||||
| CVE-2025-11468 | 2026-03-03 | N/A | N/A | ||
| When folding a long comment in an email header containing exclusively unfoldable characters, the parenthesis would not be preserved. This could be used for injecting headers into email messages where addresses are user-controlled and not sanitized. | |||||
| CVE-2026-28296 | 2026-02-27 | N/A | 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-2026-23829 | 1 Axllent | 1 Mailpit | 2026-02-23 | N/A | 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-2026-1714 | 2026-02-18 | N/A | 8.6 HIGH | ||
| The ShopLentor – WooCommerce Builder for Elementor & Gutenberg +21 Modules – All in One Solution plugin for WordPress is vulnerable to Email Relay Abuse in all versions up to, and including, 3.3.2. This is due to the lack of validation on the 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters in the 'woolentor_suggest_price_action' AJAX endpoint. This makes it possible for unauthenticated attackers to send arbitrary emails to any recipient with full control over the subject line, message content, and sender address (via CRLF injection in the 'wlemail' parameter), effectively turning the website into a full email relay for spam or phishing campaigns. | |||||
| CVE-2026-1299 | 2026-02-13 | N/A | N/A | ||
| The email module, specifically the "BytesGenerator" class, didn’t properly quote newlines for email headers when serializing an email message allowing for header injection when an email is serialized. This is only applicable if using "LiteralHeader" writing headers that don't respect email folding rules, the new behavior will reject the incorrectly folded headers in "BytesGenerator". | |||||
| CVE-2026-22777 | 1 Comfy | 1 Comfyui-manager | 2026-02-05 | N/A | 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-2025-41376 | 1 Limesurvey | 1 Limesurvey | 2026-01-30 | N/A | 5.3 MEDIUM |
| CRLF Injection vulnerability in Limesurvey v2.65.1+170522. This vulnerability could allow a remote attacker to inject arbitrary HTTP headers and perform HTTP response splitting attacks via '/index.php/survey/index/sid/<SID>/token/fwyfw%0d%0aCookie:%20POC'. | |||||
| CVE-2026-23953 | 1 Linuxcontainers | 1 Incus | 2026-01-30 | N/A | 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-2026-24489 | 2026-01-27 | N/A | 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-2026-0672 | 2026-01-26 | N/A | N/A | ||
| When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, and parameters. | |||||
| CVE-2025-15282 | 2026-01-26 | N/A | N/A | ||
| User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL mediatype. | |||||
| CVE-2025-54972 | 1 Fortinet | 1 Fortimail | 2026-01-14 | N/A | 4.3 MEDIUM |
| An improper neutralization of crlf sequences ('crlf injection') vulnerability in Fortinet FortiMail 7.6.0 through 7.6.3, FortiMail 7.4.0 through 7.4.5, FortiMail 7.2 all versions, FortiMail 7.0 all versions may allow an attacker to inject headers in the response via convincing a user to click on a specifically crafted link | |||||
| CVE-2025-8419 | 1 Redhat | 1 Keycloak | 2026-01-08 | N/A | 5.3 MEDIUM |
| A vulnerability was found in Keycloak-services. Special characters used during e-mail registration may perform SMTP Injection and unexpectedly send short unwanted e-mails. The email is limited to 64 characters (limited local part of the email), so the attack is limited to very shorts emails (subject and little data, the example is 60 chars). This flaw's only direct consequence is an unsolicited email being sent from the Keycloak server. However, this action could be a precursor for more sophisticated attacks. | |||||
| CVE-2026-21428 | 1 Yhirose | 1 Cpp-httplib | 2026-01-06 | N/A | 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. | |||||
