Overview
A sensitive information disclosure vulnerability, identified as CVE-2025-4618, has been discovered in Palo Alto Networks Prisma® Browser.

This poses a significant risk to the confidentiality of data processed and stored by the browser.
Technical Details
CVE-2025-4618 is a sensitive information disclosure vulnerability. The exact mechanism by which the data is leaked is not publicly detailed at this time, but it involves a local user gaining unauthorized access to data stored or managed by the Prisma Browser. The vulnerability stems from inadequate access control mechanisms within the browser itself.
