Active exploitationNonot in the CISA catalog
Public exploitAvailableProof of concept on GitHub (unverified)

A vulnerability has been discovered in Vue, that allows an attacker to perform XSS via prototype pollution. The attacker could change the prototype chain of some properties such as `Object.prototype.staticClass` or `Object.prototype.staticStyle` to execute arbitrary JavaScript code.

Score date
11/3/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
