Title
Apache CXF: OAuth2: Log Injection via Unsanitized Client Identifier
Summary
The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.

Title
Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections
Summary
Metrics::Any::Adapter::Statsd versions before 0.04 for Perl does not protect against metric injections.
The statsd protocol (and extensions) allow mutiple metrics,separated by newlines, to be sent per packet.
The send method does not validate the contents of the metric names or values. If the names have newlines and statsd control characters (colon, pipe) then metric injections are possible.
Version 0.04 fixed this by modifying the _make method to block metric names with characters below ASCII 32 (which includes the newline), or colons or pipes.

Title
Metrics::Any::Adapter::SignalFx versions before 0.04 for Perl does not protect against metric injections
Summary
Metrics::Any::Adapter::SignalFx versions before 0.04 for Perl does not protect against metric injections.
The statsd protocol (and extensions such as dogstatsd) allow mutiple metrics,separated by newlines, to be sent per packet.
Metrics::Any::Adapter::SignalFx which extends Metrics::Any::Adapter::Statsd, which has a similar vulnerability.
In addition, the _labels function does not check tags labels newlines or statsd control characters. The labels can be used for metric injections.

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.

CVE-2026-9270 (GCVE-0-2026-9270)

Title
DataDog::DogStatsd versions through 0.07 for Perl allow metric injections
Summary
DataDog::DogStatsd versions through 0.07 for Perl allow metric injections.
DataDog::DogStatsd does not properly sanitise input, allowing metric injections of data from untrusted sources.
The send_stats method does not remove newlines from metric names ($stat variable), allowing attackers to change the metric name prefix.
The send_stats method does not validate the content of the value ($delta variable), allowing attackers to inject metrics, especially from methods that do not restrict the data type for the value, such as set, gauge, count and histogram.
The send_stats method does not validate the content of the tags, which may contain newlines, pipes and colons that allow metric injections.
Note that the SYNOPSIS shows an example of passing a website form "loginName" parameter as a tag, which is unsafe.

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.
