Exploitation evidence

Disclosed: evidence found.
CVE published 27 May 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
Observed by OffSeq MirageSeen by Mirage: 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 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.

What to do

Upgrade SUSE to 4.16.30.

AI-suggested

A fix is available in Red Hat OpenShift Container Platform version 4.16.30. Users should upgrade to this version using the OpenShift CLI or web console following Red Hat's documented cluster upgrade procedures. No additional mitigations are specified beyond applying this update. The vendor advisory confirms the update fully addresses these vulnerabilities.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.16.30. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2025:0143 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.openshift.com/container-platform/4.16/release_notes/ocp-4-16-release-notes.html Security Fix(es): * golang.org/x/net/html: Non-linear parsing of case-insensitive content in golang.org/x/net/html (CVE-2024-45338) * unbound: Unbounded name compression could lead to Denial of Service (CVE-2024-8508) * GraphQL: Information Disclosure via GraphQL Introspection in OpenShift (CVE-2024-50312) 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. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.openshift.com/container-platform/4.16/updating/updating_a_cluster/updating-cluster-cli.html

Impact

The vulnerabilities fixed in this update can lead to denial of service conditions and information disclosure within OpenShift Container Platform environments. Specifically, unbounded name compression in unbound could cause service disruption, and GraphQL introspection could expose sensitive information. The golang.org/x/net/html parsing issue may affect processing of HTML content. These issues pose a high security risk if left unpatched.

Summary

This advisory covers security fixes in Red Hat OpenShift Container Platform 4.16.30, specifically addressing three CVEs: CVE-2024-8508 (unbounded name compression in unbound leading to denial of service), CVE-2024-50312 (information disclosure via GraphQL introspection), and CVE-2024-45338 (non-linear parsing of case-insensitive content in golang.org/x/net/html). The update is delivered as container images and RPM packages. Red Hat rates the security impact as important and recommends all users of OpenShift Container Platform 4.16 upgrade to 4.16.30. The advisory includes references to official errata and release notes for further details and upgrade guidance.

CWE-606Unchecked Input for Loop Condition (opens in a new tab)
Base weakness
The product does not properly check inputs that are used for loop conditions, potentially leading to a denial of service or other consequences because of excessive looping.
Implementation
Do not use user-controlled data for loop conditions.
Implementation
Perform input validation.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
