Exploitation evidence

CVE published 11 Apr 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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

Upgrade Red Hat to 4.3.3-r0.

Impact

The vulnerability can cause significant resource exhaustion on affected systems, resulting in degraded performance or system crashes due to high CPU and memory usage. This impacts availability by enabling Denial of Service conditions when processing maliciously crafted HTTP responses. There is no impact on confidentiality or integrity. No known exploits in the wild have been reported at this time.

Summary

CVE-2026-44432 is a vulnerability in urllib3, a Python HTTP client library, that allows a remote attacker to cause excessive resource consumption on the client side. The issue arises when urllib3 decompresses an entire HTTP response regardless of partial reads or connection draining, leading to high CPU and memory usage. This improper handling of highly compressed data (CWE-409) can result in a Denial of Service (DoS) condition. Red Hat Hardened Images RPMs including python-cryptography and python3-cryptography packages have been updated to mitigate this vulnerability. The advisory references Red Hat security advisory RHSA-2026:24014 and provides updated package versions for affected architectures.
