Two New Vuetify 2.x Vulnerabilities Just Dropped — What You Need to Know

Vuetify 2.x just added two more security issues to its growing list of unpatched vulnerabilities: a High-severity Prototype Pollution flaw and a Medium-severity XSS vulnerability.

Both have been assigned CVEs and both impact a huge number of apps still running Vuetify 2.x in production.

And since Vuetify 2 is now End-of-Life, none of these vulnerabilities will ever be fixed upstream.

This FAQ breaks down what engineering, security, and platform teams actually need to know — without forcing you to dive into every technical detail. 

‍

What exactly was discovered?

Two separate vulnerabilities affecting Vuetify 2.x:

1. CVE-2025-8083 — Prototype Pollution (High Severity)

This issue allows attackers to poison JavaScript object prototypes during Vuetify initialization.

Prototype Pollution is one of the most dangerous classes of JavaScript vulnerabilities because it can silently alter app behavior, escalate privileges, or destabilize both client-side and server-side processes.

‍

2. CVE-2025-8082 — XSS in VDatePicker (Medium Severity)

Unsanitized output in the titleDateFormat prop allows attackers to inject arbitrary JavaScript into the DOM.

Any app using Vuetify’s date-picker component with a custom title formatter is a potential target.

Who is impacted?

If you’re using Vuetify 2.x, you’re almost certainly affected.

• Prototype Pollution: Vuetify >=2.2.0-beta.2 <3.0.0-alpha.10
• XSS in VDatePicker: Vuetify >=2.0.0 <3.0.0
  
  

Because Vuetify 2.x is embedded in dashboards, customer portals, design systems, admin interfaces, and SSR workloads, the blast radius is wide.

‍

Why do these vulnerabilities matter more than a typical front-end bug?

Three reasons:

1. Vuetify 2 is EOL — no upstream patches.

Every new CVE creates a permanent risk surface unless you have a commercial support patch.

2. The vulnerabilities target core behaviors.

• Prototype Pollution can impact the entire JavaScript runtime.
• XSS can compromise users, sessions, and downstream infrastructure.
  

3. Attackers love targeting unmaintained components.

Once a project reaches EOL, the exploit window only gets larger — never smaller.

‍

Is My Application at Immediate Risk?

Yes.

Both CVE entries include straightforward proof-of-concept repro steps that demonstrate exploitation. No advanced knowledge is needed.

If your app accepts user-controlled input or dynamic configuration, the attack path is even more straightforward.

‍

Does this affect Server-Side Rendering?

Yes — and that’s a big concern.

Because the Prototype Pollution flaw exists inside the mergeDeep utility that runs during initialization, it can contaminate the server process during SSR.

That means:

• polluted global state
• corrupted responses
• potential crashes
• unexpected behavior in unrelated components

This is one of the reasons CVE-2025-8083 carries a High-severity rating.

‍

What should teams do right now?

You’ve got three realistic options:

1. Migrate off Vuetify 2.x

Great long-term move. Rarely feasible short-term.

2. Attempt custom hardening

Input validation, sanitation, defensive coding.

Useful — but still leaves the underlying framework flaw intact.

3. Apply supported patches through HeroDevs NES

HeroDevs maintains patched, drop-in-compatible Vuetify 2 builds, including fixes for both vulnerabilities. This eliminates the CVEs without forcing a rewrite.

If your organization needs to remove these issues from your SBOM or pass compliance checks, this is the fastest path. Learn more about Never-Ending Support for Vue 2 + Essentials.

‍

Bottom line

Vuetify 2.x continues to accumulate vulnerabilities — and none will be fixed by the project maintainers due to its end-of-life status.

If your organization depends on Vuetify 2, the cost of doing nothing grows with every new CVE.
