Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 13 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Red Hat states that available mitigation options do not meet their criteria for ease of use, deployment, or applicability. Users should avoid following untrusted or external redirects in applications using HTTP::Tiny, especially when sending sensitive headers. Review and restrict usage of HTTP::Tiny in contexts where credential leakage could occur.

Description

CVE-2026-7017 is a vulnerability in the HTTP::Tiny Perl module used in Red Hat Hardened Images. It allows a remote attacker to obtain sensitive credential headers such as Authorization, Cookie, and Proxy-Authorization by exploiting cross-origin redirects. The flaw occurs because HTTP::Tiny does not verify if a redirect leads to the same origin, potentially leaking credentials when redirected to a different origin, including from HTTPS to HTTP. Red Hat rates this vulnerability as Moderate due to the specific conditions required for exploitation and the limited use of HTTP::Tiny in authenticated requests within Red Hat environments. No direct fix is currently available, and mitigation options are limited.

Impact

The vulnerability can lead to unintended disclosure of sensitive credential headers (Authorization, Cookie, Proxy-Authorization) to a different origin due to improper redirect validation. This could allow remote attackers to obtain credentials if an application using HTTP::Tiny follows redirects to malicious endpoints. However, the risk is constrained by the requirement that the application issues authenticated requests to compromised or open redirect endpoints. Within Red Hat environments, the impact is limited because HTTP::Tiny is typically used in controlled scenarios. There is no indication of active exploitation in the wild.

Summary

CVE-2026-7017 affects the HTTP::Tiny Perl module by allowing credential headers to be disclosed when following HTTP redirects to a different origin. The vulnerability arises from a lack of origin validation on redirects, enabling an attacker to capture sensitive headers if a user’s request is redirected to a malicious or compromised endpoint. Red Hat classifies this as a Moderate severity issue because exploitation requires an application to send authenticated requests to a compromised or open redirector endpoint. HTTP::Tiny is mainly used in localized tooling and administrative tasks within Red Hat products, limiting the exposure. The advisory notes no current mitigation meets Red Hat’s criteria for ease of use and applicability, and a patch or fix is not explicitly stated as available in the advisory.
