CVE-2026-0323: Palo Alto Networks Checkov by Prisma Cloud SSRF

CVE-2026-0323 · Severity: info · Published 2026-11-11

Checkov by Prisma Cloud is a configuration scanning tool used to check Terraform and other infrastructure-as-code files for security issues. A server-side request forgery vulnerability allows a local attacker with access to Checkov to make unauthorized network requests to internal services on the host. This could enable lateral movement to internal systems or data exfiltration if Checkov is run on untrusted Terraform configurations.

Quick answers

Is CVE-2026-0323 exploited in the wild?: No. Junglewise Threat Intelligence has no report of CVE-2026-0323 being exploited in the wild.
How severe is CVE-2026-0323?: Informational severity, published 11 November 2026.
Which products and versions are affected?: Palo Alto Networks Checkov by Prisma Cloud 3.4.0 through 3.4.1.
Is there a fix for CVE-2026-0323?: Yes: fixed in 3.4.2. Until then: Disable external module downloading by ensuring --download-external-modules is not set to true and download-external-modules is not enabled in configuration files. Alternatively, avoid running Checkov on untrusted Terraform configurations and pass configuration explicitly via trusted configuration files rather than allowing auto-loading from the scanned directory. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

How to fix

Fixed in: 3.4.2

Disable external module downloading by ensuring --download-external-modules is not set to true and download-external-modules is not enabled in configuration files. Alternatively, avoid running Checkov on untrusted Terraform configurations and pass configuration explicitly via trusted configuration files rather than allowing auto-loading from the scanned directory.

Technical details

The SSRF vulnerability exists in Checkov's external Terraform module download functionality (CWE-918), triggered when scanning untrusted Terraform configurations with the --download-external-modules option enabled. A local unauthenticated attacker can craft malicious Terraform code to force Checkov to make unintended network requests to internal services. The vulnerability requires both external module downloading to be enabled and passive user interaction (scanning the attacker's Terraform files).
