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 26 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.
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.

What to do

Upgrade cpython to 3.8.19.

AI-suggested

Red Hat has released updated python3 packages for Red Hat Enterprise Linux 8 that address this vulnerability. Users should apply the official security update as described in Red Hat advisory RHSA-2024:4243 and the referenced article https://access.redhat.com/articles/11258. Applying this update mitigates the zip-bomb denial of service vulnerability. No additional mitigation steps are indicated by the vendor.

Description

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python: The zipfile module is vulnerable to zip-bombs leading to denial of service (CVE-2024-0450) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Exploitation of this vulnerability can lead to denial of service by processing specially crafted zip files (zip-bombs) that consume excessive system resources. This can disrupt applications or services relying on the Python zipfile module, potentially causing crashes or unresponsiveness. There is no indication of code execution or data disclosure impacts in the advisory.

Summary

The Python zipfile module in Red Hat Enterprise Linux 8's python3 package is vulnerable to zip-bomb attacks that can cause denial of service (CVE-2024-0450). This vulnerability arises from the module's handling of compressed zip files that expand excessively, exhausting system resources. Red Hat has issued a security advisory (RHSA-2024:4243) and released updated python3 packages to fix this issue. The advisory covers multiple architectures including x86_64, s390x, ppc64le, and aarch64. No CVSS score is provided, but the impact is classified as moderate. The vendor advisory includes instructions for applying the update and references the CVE for further details.

CWE-450Multiple Interpretations of UI Input (opens in a new tab)
Base weakness
The UI has multiple interpretations of user input but does not prompt the user when it selects the less secure interpretation.
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.
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).
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
