Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.

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 10 Nov 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 4.12.92.

Impact

The vulnerability allows remote attackers to access sensitive information that was previously deleted but not fully removed from the system due to stale references in caching mechanisms. This results in unauthorized disclosure of confidential data. There is no impact on integrity or availability. No known exploitation in the wild has been reported.

Summary

CVE-2026-35172 is a security vulnerability in Distribution, a container content management toolkit used by Red Hat OpenShift Container Platform. When certain caching and deletion features are enabled, the system fails to fully remove all references to deleted content, allowing remote attackers to read previously deleted data. This constitutes an information disclosure vulnerability classified under CWE-524 (Use of Cache Containing Sensitive Information). Red Hat has issued OpenShift Container Platform 4.12.92 as a security update containing fixes for this issue. The vulnerability has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
