CVE-2026-0274Network attack vector

Unauthenticated access and modification of protected resources

Published Jun 10, 2026 · Updated Jun 10, 2026

Weak authentication in CommvaultSecurityIQ Marketplace 1.1.0 through 1.1.9 allows remote attackers to access and modify protected resources. Palo Alto Networks has not published the credential-validation locus or how credentials are improperly validated. Network access is sufficient and no special configuration is required; the documented consequence is unauthorized access to and modification of protected resources.
