Overview
CVE-2025-4617 details a security vulnerability found in Palo Alto Networks Prisma® Browser running on Windows operating systems. This flaw allows a locally authenticated, non-administrative user to bypass the screenshot control feature of the browser. This means that a user with limited privileges on a compromised system could potentially take screenshots of sensitive information displayed within the Prisma Browser, even when such functionality is restricted by policy.
Technical Details
The vulnerability stems from insufficient policy enforcement within the Prisma Browser’s screenshot control mechanism. The specific technical details of the bypass are not publicly available to prevent further exploitation, but the core issue is a lack of robust validation checks that allow a non-admin user to circumvent the intended restrictions. This suggests a possible flaw in the privilege separation or API usage within the application.
CVSS Analysis
As of the published date, a CVSS score and severity rating are not available for CVE-2025-4617. This might be because the vulnerability is newly discovered, or because Palo Alto Networks is still evaluating its impact. However, the ability to bypass security controls warrants immediate attention, especially in environments where data security and confidentiality are paramount.
Possible Impact
The potential impact of CVE-2025-4617 is significant, particularly in organizations that rely on Prisma Browser to protect sensitive data. Successful exploitation of this vulnerability could lead to:
- Unauthorized access to confidential information displayed within the browser.
- Data leakage and compliance violations.
- Circumvention of security policies designed to prevent data exfiltration.
- Compromise of sensitive credentials or other protected information.
