CWE-93
Improper Neutralization of CRLF Sequences ('CRLF Injection')
The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.
CVE-2026-47075 (GCVE-0-2026-47075)
Vulnerability from cvelistv5 – Published: 2026-05-25 14:00 – Updated: 2026-05-27 15:41

Title
CR/LF injection in query parameter in hackney
Summary
Improper Neutralization of CRLF Sequences vulnerability in benoitc hackney allows HTTP Request Splitting. hackney does not percent-encode carriage return (\r) or line feed (\n) characters in the URL query component before constructing the HTTP/1.1 request target. Characters outside the grammar defined in RFC 3986 Section 3.4 must be percent-encoded, but hackney_url:make_url/3 passes the query binary directly without validation or escaping. An attacker who can control all or part of a URL passed to hackney can inject raw CRLF sequences into the query string, which are then sent as HTTP line breaks in the request target. This enables injection of arbitrary HTTP headers or splitting of the HTTP request.
This issue affects hackney: from 0 before 4.0.1.

Title
Music Player Daemon < 0.24.11 CRLF Injection via XspfPlaylistPlugin.cxx
Summary
Music Player Daemon (MPD) before version 0.24.11 contains a CRLF injection vulnerability in the xspf_char_data function within the XSPF playlist plugin that allows attackers to embed literal CR/LF bytes in URI fields by supplying a malicious XSPF playlist with XML numeric character references. Attackers can inject forged key-value lines through the location field into MPD protocol responses including playlistinfo, currentsong, and listplaylist outputs, as well as the state file writer, by exploiting Expat's decoding of numeric character references prior to the character data callback.

Title
Net::Statsd::Lite versions through 0.10.0 for Perl allowed metric injections
Summary
Net::Statsd::Lite versions through 0.10.0 for Perl allowed metric injections.
The values from the set_add method were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics.
Note that version 0.9.0 fixed a similar issue CVE-2026-46719 for metric names.
Severity
7.3 (High)

Mitigation
Phase: Implementation
Description:
- Avoid using CRLF as a special sequence.
Mitigation
Phase: Implementation
Description:
- Appropriately filter or quote CRLF sequences in user-controlled input.
CAPEC-15: Command Delimiters
An attack of this type exploits a programs' vulnerabilities that allows an attacker's commands to be concatenated onto a legitimate command with the intent of targeting other resources such as the file system or database. The system that uses a filter or denylist input validation, as opposed to allowlist validation is vulnerable to an attacker who predicts delimiters (or combinations of delimiters) not present in the filter or denylist. As with other injection attacks, the attacker uses the command delimiter payload as an entry point to tunnel through the application and activate additional attacks through SQL queries, shell commands, network scanning, and so on.
CAPEC-81: Web Server Logs Tampering
Web Logs Tampering attacks involve an attacker injecting, deleting or otherwise tampering with the contents of web logs typically for the purposes of masking other malicious behavior. Additionally, writing malicious data to log files may target jobs, filters, reports, and other agents that process the logs in an asynchronous attack pattern. This pattern of attack is similar to "Log Injection-Tampering-Forging" except that in this case, the attack is targeting the logs of the web server and not the application.
