CVE-2025-4617 is a vulnerability classified under CWE-424 (Improper Protection of Alternate Path) affecting Palo Alto Networks Prisma Browser version 142.15.6.0 on Windows platforms. The flaw arises from insufficient policy enforcement that allows a locally authenticated non-administrative user to bypass the browser's screenshot control feature. Normally, Prisma Browser includes mechanisms to prevent unauthorized screenshots to protect sensitive information displayed within the browser. However, due to improper handling of alternate paths or insufficient self-protection, a non-admin user can circumvent these controls and capture screenshots despite restrictions. The vulnerability does not require elevated privileges beyond local user access, nor does it require user interaction, making it easier to exploit in environments where multiple users share the same machine or where local user accounts are not tightly controlled. The CVSS 4.0 base score is 1.1, indicating low severity, primarily because the attack vector is local, the impact is limited to confidentiality, and no integrity or availability impacts are present. No known exploits have been reported in the wild, and no patches have been published as of the vulnerability disclosure date (November 14, 2025). Mitigation relies on enabling the browser's self-protection features and enforcing strict local user access policies.

The primary impact of CVE-2025-4617 is the potential unauthorized disclosure of sensitive information through screenshots taken by non-admin local users. For European organizations, especially those handling confidential or regulated data within Prisma Browser, this could lead to data leakage risks. While the vulnerability does not allow remote exploitation or privilege escalation, environments with shared workstations or insufficient local user controls are at higher risk. The breach of confidentiality could affect sectors such as finance, healthcare, government, and critical infrastructure where Prisma Browser is deployed. However, the low CVSS score and lack of known exploits suggest limited immediate risk. Still, the vulnerability could be leveraged in insider threat scenarios or combined with other attack vectors to facilitate data exfiltration. Organizations must consider the risk in the context of their local user management and data sensitivity.

1. Enable Prisma Browser's self-protection feature immediately to enforce screenshot control policies effectively. 2. Restrict local user access on Windows systems running Prisma Browser to trusted personnel only, minimizing the number of non-admin users with local access. 3. Implement strict endpoint security controls, including application whitelisting and user privilege management, to prevent unauthorized local actions. 4. Monitor local user activities and audit access to sensitive applications and data to detect potential misuse. 5. Apply network segmentation and data loss prevention (DLP) solutions to reduce the impact of any unauthorized data capture. 6. Stay updated with Palo Alto Networks advisories for patches or updates addressing this vulnerability and apply them promptly once available. 7. Educate users about the risks of local data capture and enforce policies against unauthorized information disclosure. 8. Consider deploying endpoint detection and response (EDR) tools capable of detecting suspicious screenshot or screen capture activities.
