Trust Protection Foundation: Exposure of Sensitive System Information to an Unauthorized Control Sphere
CVE-2026-0240 is a high-severity exposure of sensitive system information to an unauthorized control sphere vulnerability in Trust Protection Foundation from Palo Alto Networks, with a CVSS 3.1 base score of 8.7 out of 10. It can be exploited from the same local network by an attacker with a low-privileged account, without any action from a user. The record lists versions 25.3.3, 25.1.8, 24.3.6 as the first without the flaw, so updating Trust Protection Foundation to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.24% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Trust Protection Foundation to 25.3.3 or 25.1.8 or 24.3.6 or 24.1.13, whichever matches your release line, or a later version.
- Read the advisory on security.paloaltonetworks.com for workarounds and exact fixed builds.

Official description
An information disclosure vulnerability in Trust Protection Foundation enables an authenticated attacker to obtain sensitive information from the server's vault. Successful exploitation of this issue allows the attacker to impersonate any user within the environment and arbitrarily modify configuration settings.

The underlying weakness: Exposure of Sensitive System Information to an Unauthorized Control Sphere
The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.
How developers prevent this class of flaw
- Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user. All error message text should be HTML entity encoded before being written to the log file to protect against potential cross-site scripting attacks against the viewer of the logs
