In Apache CloudStack, a gap in access control checks affected the APIs - createNetworkACL - listNetworkACLs - listResourceDetails - listVirtualMachinesUsageHistory - listVolumesUsageHistory While. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
In Apache CloudStack improper control of generation of code ('Code Injection') vulnerability is found in the following APIs which are accessible only to admins. Rated medium severity (CVSS 4.7), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
In Apache CloudStack, a flaw in access control affects the listTemplates and listIsos APIs. A malicious Domain Admin or Resource Admin can exploit this issue by intentionally specifying the 'domainid' parameter along with the 'filter=self' or 'filter=selfexecutable' values. This allows the attacker to gain unauthorized visibility into templates and ISOs under the ROOT domain. A malicious admin can enumerate and extract metadata of templates and ISOs that belong to unrelated domains, violating isolation boundaries and potentially exposing sensitive or internal configuration details. This vulnerability has been fixed by ensuring the domain resolution strictly adheres to the caller's scope rather than defaulting to the ROOT domain. Affected users are recommended to upgrade to Apache CloudStack 4.19.3.0 or 4.20.1.0.
A privilege escalation vulnerability in Apache CloudStack (CVSS 8.8) that allows the attacker. High severity vulnerability requiring prompt remediation.
A privilege escalation vulnerability in Apache CloudStack (CVSS 8.8) that allows the attacker. High severity vulnerability requiring prompt remediation.
CVE-2025-26521 is a security vulnerability (CVSS 8.1). High severity vulnerability requiring prompt remediation.
The CloudStack Quota plugin has an improper privilege management logic in version 4.20.0.0. Anyone with authenticated user-account access in CloudStack 4.20.0.0 environments, where this plugin is enabled and have access to specific APIs can enable or disable reception of quota-related emails for any account in the environment and list their configurations. Quota plugin users using CloudStack 4.20.0.0 are recommended to upgrade to CloudStack version 4.20.1.0, which fixes this issue.
CloudStack users can add and read comments (annotations) on resources they are authorised to access. Rated medium severity (CVSS 4.3), this vulnerability is remotely exploitable, low attack complexity. Epss exploitation probability 18.4% and no vendor patch available.
