CVE-2026-7017
Description
A flaw was found in HTTP::Tiny. This vulnerability allows a remote attacker to obtain sensitive credential headers, such as Authorization, Cookie, and Proxy-Authorization, by redirecting a user's request to a different origin. When HTTP::Tiny follows a server's redirect, it fails to verify if the new destination shares the same origin as the original request. This can lead to the unintended disclosure of credentials, including over unencrypted connections if redirected from HTTPS to HTTP.
Statement
Red Hat has rated this vulnerability as Moderate because exploitation relies on a specific sequence where an application issues authenticated requests to a compromised endpoint or an open redirector that routes traffic across domains. Within Red Hat environments, the HTTP::Tiny client library is typically used by localized tooling and administrative tasks connecting to predetermined services. The risk of credential leakage is therefore constrained to setups where scripts explicitly pass sensitive headers and follow unvetted external HTTP redirects.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
