Countdown to Chaos – The Looming Collapse of CVE and What it Means for Global Cybersecurity

On April 16, 2025, the cybersecurity world faces an alarming crossroads. MITRE’s stewardship of the Common Vulnerabilities and Exposures (CVE) program, a foundational pillar of global cybersecurity, is set to expire without a clear path for renewal. This looming deadline threatens to plunge the cybersecurity community into dangerous darkness, potentially halting our collective ability to identify, track, and mitigate critical vulnerabilities.

For over two decades, the CVE program has served as an essential language connecting researchers, vendors, security teams, and government agencies. CVEs provide standardised identifiers for vulnerabilities, ensuring clear communication, swift action, and coordinated responses. Alongside the Common Weakness Enumeration (CWE), which categorises coding weaknesses leading to these vulnerabilities, these programs underpin nearly every aspect of modern cybersecurity, from threat intelligence to patch management.

The potential cessation of this critical program is deeply troubling. As CEO of Custodian360, I am profoundly concerned about what this means, not just for our company, but for the global cybersecurity ecosystem. Without an operational CVE program, we risk losing visibility into emerging threats precisely when rapid detection and remediation are most crucial.

One of our threat hunters here at Custodian360 described it starkly: “Without active CVE assignments, the cybersecurity community would effectively be flying blind. Vulnerabilities would go untracked, uncommunicated, and unaddressed. This is not just a minor hiccup, it is a potential catastrophe.”

This situation is further worsened by the absence of any confirmed contingency plan. MITRE has indicated historical CVE records will remain accessible, but without ongoing funding, new vulnerabilities will no longer receive standardised identifiers. This would significantly disrupt the mechanisms that security professionals rely on daily.

The CVE program isn’t just another security tool, it is the backbone of vulnerability management, incident response, and our ability to safeguard critical infrastructure. If CVE assignments stop, we are not just inconvenienced, we are facing a ticking clock toward a potential national security crisis.

This is not alarmism, it is our reality. We must recognise this looming disaster and take immediate action.

Our security analyst, @Akhila Krishna  at Custodian360 adds, “The CVE shutdown would be catastrophic. It would unravel the trust we have long built into the systems designed to keep society safe. There needs to be immediate action to prevent this lapse.”

If the CVE program goes dark, organisations must urgently reassess their security posture and preparedness. Here are critical questions you need to ask your cybersecurity providers now:

1. How will you track and communicate vulnerabilities if the CVE system is disrupted?
2. What alternative measures do you have in place for finding emerging threats?
3. How quickly can you adapt your processes if CVE identifiers are unavailable?
4. Can you provide detailed contingency plans to ensure continuity in vulnerability management?
5. What will your communication plan look like during this disruption?

Expect clear, concrete answers. Providers should have robust contingency plans already in place, including alternative vulnerability tracking methods, enhanced threat intelligence mechanisms, and clear communication strategies to keep transparency with customers.

This is not merely a funding cut, it is a potential crisis. It is yet another stark reminder that foundational cybersecurity infrastructure cannot be subject to yearly uncertainty. The industry needs stable, reliable, and long-term commitments from policymakers to avoid moments like this one.

We urge policymakers and stakeholders to act swiftly to secure immediate funding for the CVE program and commit to establishing sustainable governance structures to prevent future disruptions. Our collective security and the stability of digital infrastructures depend on it.

Let this serve as a wake-up call. In cybersecurity, clarity is security. Allowing the CVE program to lapse, even briefly, in the current climate is an unacceptable risk we simply cannot afford.
