This low-severity CVE scores 3.8 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 58% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

An information exposure through log file vulnerability exists in the Palo Alto Networks Prisma Cloud Compute Console where a secret used to authorize the role of the authenticated user is logged to a debug log file. Authenticated Operator role and Auditor role users with access to the debug log files can use this secret to gain Administrator role access for their active session in Prisma Cloud Compute. Prisma Cloud Compute SaaS versions were automatically upgraded to the fixed release. This issue impacts all Prisma Cloud Compute versions earlier than Prisma Cloud Compute 21.04.412.
