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 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

AI-suggested

Red Hat currently does not provide a mitigation that meets its criteria for ease of use, applicability, or stability. The recommended action is to upgrade Red Hat OpenShift Builds from version 1.3.z to 1.4.1, which addresses this vulnerability. Users should monitor Red Hat advisories for any future patches or mitigations. No other specific mitigations are advised at this time.

Description

CVE-2025-47273 is a path traversal vulnerability in the Python setuptools library used by Red Hat OpenShift Builds 1.4.1. It allows attackers with limited code execution access to write files outside the intended temporary directory by manipulating package download URLs. This can lead to unauthorized overwrites of important system files, potentially causing persistent code execution or system misconfiguration. The vulnerability does not expose data or require user interaction and does not cross security boundaries such as container isolation. Red Hat rates this vulnerability as moderate in severity.

Impact

Successful exploitation allows an attacker with limited code execution privileges to write arbitrary files outside the intended directory, potentially overwriting critical system files. This can lead to persistent code execution, system misconfiguration, or unauthorized behavior in automated environments. The vulnerability does not expose confidential data, does not require user interaction, and does not cross trust boundaries such as between containers or kernel space. It does not inherently cause denial of service, though service disruption is theoretically possible if critical files are overwritten.

Summary

This vulnerability (CVE-2025-47273) affects the setuptools PackageIndex.download() function, where insufficient sanitization of package download URLs permits path traversal attacks. An attacker with limited code execution privileges in a Python environment can write arbitrary files outside the intended directory, potentially overwriting critical configuration files, executables, or scripts. Exploitation requires the attacker to have some level of code execution access but does not require full administrative privileges. The flaw impacts system integrity within the same security boundary but does not provide access to existing files or confidential information. Red Hat OpenShift Builds 1.4.1 users are advised to upgrade from 1.3.z to 1.4.1.

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).
