Answer in brief
CVE-2026-0257 records a High severity vulnerability in PAN-OS: GlobalProtect Authentication Bypass Vulnerabilities. The current sources mark it as known exploited. The current feed maps Palo Alto Networks/PAN-OS (generic), Palo Alto Networks/Prisma Access (generic), Siemens/RUGGEDCOM APE1808 (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.
