A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), GitHub proofs of concept, the Metasploit, Exploit-DB and nuclei-templates index as of 31 Oct 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.

What to do

Upgrade Red Hat python3.11-setuptools to 9.2.2.

AI-suggested

Red Hat has released an official security update for python3.11-setuptools to fix this vulnerability. Users of Red Hat Enterprise Linux 9.2 and related variants should apply the update as described in Red Hat advisory RHSA-2025:13803 and the update instructions at https://access.redhat.com/articles/11258. Applying this update mitigates the vulnerability.

Description

A path traversal vulnerability (CVE-2025-47273) was identified in the setuptools PackageIndex component of python3.11-setuptools on Red Hat Enterprise Linux 9.2. This vulnerability could allow unauthorized access to files outside the intended directory. Red Hat has rated this issue as having moderate security impact and has released an update to address it.

Impact

The path traversal vulnerability could allow an attacker to access or modify files outside the intended scope of the setuptools PackageIndex, potentially leading to unauthorized information disclosure or modification. Red Hat rates the security impact as moderate.

Summary

The vulnerability CVE-2025-47273 affects the setuptools PackageIndex in python3.11-setuptools, allowing path traversal attacks. This could enable an attacker to access or manipulate files outside the designated directories. The issue was addressed by Red Hat in an update for python3.11-setuptools on Red Hat Enterprise Linux 9.2, including various architectures such as x86_64, ppc64le, aarch64, and s390x. The advisory references Red Hat's errata RHSA-2025:13803 and provides updated package versions to remediate the vulnerability.

CWE-22Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
