Exploitation evidence

Disclosed: evidence found.
CVE published 28 Apr 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.

AI-suggested

Red Hat has released updated Submariner 0.19.4 container images for Red Hat Advanced Cluster Management for Kubernetes 2.12 on RHEL 9 that fix these vulnerabilities. Users should apply these updates promptly to mitigate the risks. The advisory does not indicate any temporary workarounds or that no action is required. Patch status is confirmed by the vendor advisory. Refer to the official Red Hat advisory RHSA-2025:4250 for detailed update instructions.

Description

Submariner enables direct networking between pods and services on different Kubernetes clusters that are either on-premises or in the cloud. For more information about Submariner, see the Submariner open source community website at: https://submariner.io/. This advisory contains bug fixes and enhancements to the Submariner container images. Security fix(es): * quic-go: quic-go affected by an ICMP Packet Too Large Injection Attack on Linux Security (CVE-2024-53259) * golang.org/x/oauth2/jws: Unexpected memory consumption during token parsing in golang.org/x/oauth2/jws Security (CVE-2025-22868) * golang-jwt/jwt: jwt-go allows excessive memory allocation during header parsing Security (CVE-2025-30204)

Impact

The vulnerabilities could allow an attacker to cause denial of service or resource exhaustion by exploiting memory consumption flaws or injecting malicious ICMP packets. This could disrupt networking between Kubernetes clusters managed by Submariner, impacting cluster communication and service availability. No known active exploitation has been reported, but the issues pose a significant risk to cluster stability and security if left unaddressed.

CWE-345Insufficient Verification of Data Authenticity (opens in a new tab)
Class weaknessOWASP Top 10 A08:2025: Software or Data Integrity Failures (opens in a new tab)
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.

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.

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.
