BREW-PERL-BUILD-CVE-2026-7010 (CVE-2026-7010)

Vulnerability from osv_homebrew – Published: 2026-08-13 10:07 – Updated: 2026-10-08 00:28 – Source website

Summary

HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP request lines or control field header values

Details

HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP request lines or control field header values.

The unvalidated inputs are the method and URI in the request line, the URL host that becomes the Host: header, and HTTP/1.1 control data field values.

An attacker who controls one of these inputs, for example a user supplied URL passed to a webhook or URL fetch endpoint, can inject additional headers and smuggle requests to the upstream server.

Severity

6.5 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
