Summary

perl-HTTP-Tiny security update

Details

This is a very simple HTTP/1.1 client, designed for doing simple requests without the overhead of a large framework like LWP::UserAgent.

Security Fix(es):

HTTP::Tiny versions before 0.095 for Perl forward credential headers to cross-origin redirect targets.

When the server returns a 3xx redirect, _maybe_redirect follows the Location: header and _prepare_headers_and_cb re-merges the caller's headers argument into the new request, without checking whether the redirect target shares an origin with the original URL. Caller-supplied Authorization, Cookie and Proxy-Authorization headers are therefore re-sent to whatever host the redirect names, across scheme, host or port boundaries, and including https to http downgrades that expose them in plaintext on the wire.

The HTTP::Tiny POD note that "Authorization headers will not be included in a redirected request" applied only to the URL-userinfo Basic-auth path, not to headers passed explicitly by the caller.(CVE-2026-7017)

Severity

7.1 (High)

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.
