Exploitation evidence

Disclosed: evidence found.
CVE published 10 Dec 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.

What to do

Upgrade Red Hat to 6.3.2.

AI-suggested

Red Hat has released OpenShift Logging version 6.3.2 which fixes this vulnerability. Users should upgrade to version 6.3.2 or later to remediate the issue. Additionally, it is recommended to pre-validate any payloads passed to the go-jose library to ensure they do not contain an excessive number of '.' characters. No other mitigations are specified by the vendor.

Description

Red Hat OpenShift Logging 6.3.2 is a cluster-wide logging solution for OpenShift that collects and manages applications, infrastructure, and audit logs.

Impact

An attacker can exploit this vulnerability by sending numerous malformed JWT tokens with many '.' characters, causing excessive memory consumption in the token parsing process. This can result in denial of service due to memory exhaustion, impacting availability of the logging subsystem in Red Hat OpenShift clusters.

Summary

The vulnerability CVE-2025-22868 affects the golang.org/x/oauth2/jws package's token parsing component, specifically due to the use of strings.Split(token, ".") to split JWT tokens. Malicious tokens with a large number of '.' characters can cause excessive memory consumption, leading to denial of service via memory exhaustion. This affects Red Hat OpenShift Logging versions >=6.3.0 and <6.3.2. Red Hat has issued an official security advisory and released OpenShift Logging 6.3.2 which includes the fix. The recommended mitigation is to pre-validate payloads passed to go-jose to ensure they do not contain excessive '.' characters.

CWE-1286Improper Validation of Syntactic Correctness of Input (opens in a new tab)
Base weakness
The product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax.
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.

CWE-405Asymmetric Resource Consumption (Amplification) (opens in a new tab)
Class weakness
The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is "asymmetric."
Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
