A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), GitHub proofs of concept, the Metasploit, Exploit-DB and nuclei-templates index as of 11 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 3.11.3, 3.5.3, 0.311.3 or 0.305.3.

AI-suggested

An official fix is available in metrics-server version 0.8.1-r5 and corresponding updated Red Hat Hardened Images RPMs as detailed in Red Hat advisories RHSA-2026:25039 and RHSA-2026:25245. Users should apply these updates promptly to remediate the vulnerabilities. No additional mitigation steps are indicated by the vendor advisories.

Description

This update includes the following RPMs: jaeger: * jaeger-2.19.0-1.hum1 (aarch64, x86_64) * jaeger-2.19.0-1.hum1.src (src)

Impact

The vulnerabilities fixed in metrics-server 0.8.1-r5 and related Red Hat Hardened Images RPMs are rated as high severity. They potentially allow attackers to exploit issues such as improper credential storage, resource exhaustion, information leakage, and improper resource handling. These could lead to unauthorized access, denial of service, or information disclosure in affected environments. However, no active exploitation has been reported to date.

Summary

The metrics-server package version 0.8.1-r5 includes fixes for six security vulnerabilities, including CVE-2026-42154, CVE-2026-42151, CVE-2026-44431, CVE-2026-44432, CVE-2026-48990, and CVE-2026-45409. These vulnerabilities correspond to CWEs such as CWE-256 (Plaintext Storage of a Password), CWE-770 (Allocation of Resources Without Limits or Throttling), CWE-201 (Information Exposure), CWE-409 (Improper Resource Shutdown or Release), and CWE-915 (Improperly Controlled Modification of Object Prototype Attributes). The affected versions span multiple version ranges of metrics-server and related Red Hat Hardened Images RPMs. Red Hat has published security advisories RHSA-2026:25039 and RHSA-2026:25245 detailing the fixes and providing updated RPM packages. Patch availability is confirmed, and no known exploits are reported in the wild.

CWE-256Plaintext Storage of a Password (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product stores a password in plaintext within resources such as memory or files.
Architecture and Design
Avoid storing passwords in easily accessible locations.
Architecture and Design
Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.

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.

Base weaknessOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.
Requirements
Specify which data in the software should be regarded as sensitive. Consider which types of users should have access to which types of data.
Implementation
Ensure that any possibly sensitive data specified in the requirements is verified with designers to ensure that it is either a calculated risk or mitigated elsewhere.
System Configuration
Setup default error messages so that unexpected errors do not disclose sensitive information.

Base weaknessOWASP Top 10 A08:2025: Software or Data Integrity Failures (opens in a new tab)
The product receives input from an upstream component that specifies multiple attributes, properties, or fields that are to be initialized or updated in an object, but it does not properly control which attributes can be modified.
Implementation
If available, use features of the language or framework that allow specification of allowlists of attributes or fields that are allowed to be modified. If possible, prefer allowlists over denylists.
Architecture and Design · Implementation
If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
Implementation · Input Validation
For any externally-influenced input, check the input against an allowlist of internal object attributes or fields that are allowed to be modified.
