About this tag
The tag covers Perl security topics, with a focus on vulnerabilities in widely used Perl modules. A key example is CVE-2023-31486, which exposed an insecure default in the HTTP::Tiny client that shipped without TLS certificate verification prior to version 0.083. This flaw risked supply chain attacks by allowing man-in-the-middle exploits in package managers, CI pipelines, and internal tooling. The fix reversed the default to secure-by-default, but the incident highlights broader lessons about default security settings and supply chain risks in Perl ecosystems. Discussions also cover how such vulnerabilities propagate through dependencies and the importance of proactive security practices in Perl development.
