CVE-2026-0248
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn improper certificate validation vulnerability in the Prisma Access Agent® for Android and Chrome OS enables an attacker to perform a man-in-the-middle (MitM) attack to intercept VPN traffic. By presenting a certificate for any domain issued by a trusted Certificate Authority, the attacker can capture sensitive device information. The Prisma Access Agent on macOS, Windows, Linux and iOS are not affected.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Prisma Access Agent for Android and Chrome OS contains an improper certificate validation vulnerability that fails to properly verify the authenticity of SSL/TLS certificates. This allows a man-in-the-middle attacker to present a certificate issued by any trusted Certificate Authority and successfully intercept VPN traffic, capturing sensitive device information.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Prisma Access Agent version on AndroidOpen the Google Play Store app, search for Prisma Access Agent, tap on it, and view the version number displayed under the app name. Alternatively, go to Settings > Apps > Prisma Access Agent to see the version.Affected if The displayed version number is lower than 26.2.1
-
Check installed Prisma Access Agent version on Chrome OSOpen the Google Play Store on Chrome OS, locate the Prisma Access Agent app, and view the version information in the app listing details.Affected if The displayed version number is lower than 26.2.1
-
Check version via app package information on AndroidUse ADB to run: adb shell pm list packages | grep prisma, then adb shell dumpsys package <package_name> | grep versionNameAffected if The versionName field shows a version lower than 26.2.1
-
Compare version to affected rangeDocument the exact version number found and compare it numerically to 26.2.1Affected if The installed version is any release prior to 26.2.1 (for example, 26.2.0, 26.1.x, 26.0.x, or earlier)
You are affected if the installed version of Prisma Access Agent on your Android device or Chrome OS is lower than 26.2.1, as the certificate validation flaw exists in all prior versions.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped26.2.1
Apply vendor patches from Palo Alto Networks for the Prisma Access Agent on Android and Chrome OS; until patches are available, users should avoid untrusted networks and organizations may consider network-level SSL inspection or additional controls.
26.2.1
- Open the Google Play Store (Android) or Chrome Web Store (Chrome OS) on the device
- Search for "Prisma Access Agent" or access it through your organization's software distribution method
- Locate Prisma Access Agent in the app store or software catalog
- Update the application to the latest available version
- Alternatively, if deployed via enterprise mobile device management (MDM), push the update 26.2.1 or later through your MDM console
- After update completes, verify the version by checking the app settings or about section to confirm version 26.2.1 or higher is installed
- Restart the VPN connection if currently active to ensure the patched client is fully operational
