Exploitation evidence

Disclosed: evidence found.
CVE published 10 Nov 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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 2026-10-25.

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.

AI-suggested

Red Hat has not released a patch or official fix for this vulnerability. Mitigation options currently available do not meet Red Hat's criteria for deployment due to complexity or limited applicability. Users are advised to ensure all previously released errata relevant to their systems are applied. Monitoring Red Hat advisories for future updates or fixes is recommended. No specific workaround is provided by Red Hat at this time.

Description

The Insights proxy Container is used by the Insights proxy product RPM and serves as an intermediary between cystomer systems in disconnected networks, air-gapped systems or systems with no outside connections and Insights. The Insights proxy routes all Red Hat Insights traffic through itself, providing a layer of privary and security for disconnected customer systems.

Impact

Successful exploitation can lead to unauthorized modification or creation of critical files, including programs or libraries, potentially allowing code execution or bypassing security mechanisms. It may also expose sensitive data or cause denial of service by corrupting essential files. The impact depends on the permissions of the process running the Insights proxy container. Red Hat rates this vulnerability as medium severity. There are no known exploits in the wild at this time.

Summary

The Red Hat Insights proxy container image contains a path traversal vulnerability (CVE-2025-53905) that allows an attacker to write files outside the intended directory scope. This could enable overwriting sensitive files or placing executable code in privileged locations, contingent on the permissions of the process editing the archive. The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). Red Hat has not provided an official patch or fix for this issue, citing lack of suitable mitigation options that meet their criteria for ease of use, applicability, and stability. The vulnerability affects the Red Hat Insights proxy container image used in disconnected or air-gapped environments to route Insights traffic securely.

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).
