Exploitation evidence

Disclosed: evidence found.
CVE published 19 May 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB

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 2026-10-26.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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 provides updated RPM packages for curl and libcurl as part of this advisory. Users should apply these updates to mitigate the vulnerability. Additionally, applications using libcurl should avoid reusing handles when switching between different HTTP proxies, especially after Digest authentication, to prevent disclosure of Proxy-Authorization headers. Patch status is not explicitly confirmed; users should refer to the Red Hat advisory and update instructions at https://images.redhat.com/ for the latest remediation guidance.

Description

This update includes the following RPMs: curl: * curl-8.20.0-2.hum1 (aarch64, x86_64) * libcurl-8.20.0-2.hum1 (aarch64, x86_64) * libcurl-devel-8.20.0-2.hum1 (aarch64, x86_64) * libcurl-minimal-8.20.0-2.hum1 (aarch64, x86_64) * curl-8.20.0-2.hum1.src (src)

Impact

The vulnerability can lead to unintended disclosure of sensitive Proxy-Authorization headers to a different HTTP proxy when libcurl handles are reused across proxy hosts using Digest authentication. This could allow an attacker controlling the second proxy to gain unauthorized access or impersonate the user. The impact is limited to confidentiality loss without integrity or availability impact. No known exploits in the wild are reported.

Summary

The advisory covers two CVEs affecting Red Hat Hardened Images RPMs, including curl and libcurl packages. CVE-2026-7168 is a vulnerability in libcurl where reusing a handle for HTTP proxy transfers with Digest authentication causes the Proxy-Authorization header from the first proxy to be sent to a second, different proxy. This results in potential disclosure of sensitive authentication information to unintended proxies. The advisory lists updated RPMs (curl-8.20.0-2.hum1 and related packages) for aarch64 and x86_64 architectures. No explicit patch availability statement is given, but updated packages are provided. The advisory recommends avoiding reuse of handles when switching proxies as a mitigation. The CVSS score is not provided by Red Hat, but the impact is rated moderate to medium.
