High [CVE-2026-63046] Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Apache InLong
Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Apache InLong. Agent Installer's ModuleManager executes arbitrary shell commands via ExcuteLinux.exeCmd() with no filtering or whitelist validation. This issue affects Apache InLong: from 2.0.0 before 2.4.0. Users are advised to upgrade to Apache InLong's 2.4.0 or cherry-pick [1]/[2] to solve it. [1]. [2].
High [CVE-2026-47359] Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Apache CloudStack's NAS backup provider plugin
Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability in Apache CloudStack's NAS backup provider plugin. The addBackupRepository API (available since 4.20.0.0) and updateBackupRepository API (introduced in 4.22.0.0) accept unsanitized command options for the backup repository. A malicious operator account can exploit this to inject arbitrary commands that execute on the KVM hypervisor host when any account subsequently performs a backup restore. This issue affects Apache CloudStack: from 4.20.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
High [CVE-2026-50112] Apache CloudStack: SSRF via Metalink Mirror URL Resolution: An authenticated tenant can register a template pointing to an attacker-controlled metalink file containing internal targets
SSRF via Metalink Mirror URL Resolution: An authenticated tenant can register a template pointing to an attacker-controlled metalink file containing internal targets. The Secondary Storage VM will retrieve the data and persist it as a template file, which can later be downloaded through normal APIs. RCE on KVM hypervisor via NFS, Metalink files with/without Direct Downloads: An authenticated CloudStack tenant holding the default User role can execute arbitrary shell commands as root on the KVM hypervisor host that runs other tenants' VMs. This is cross-tenant root on the underlying compute, reachable via the public CloudStack API. When a User registers a VM template with directDownload=true and a URL pointing to a.metalink file, the management server fetches the metalink XML and dispatches download to the KVM agent. Inner URLs inside the metalink XML are never re-validated against the scheme allowlist. These issues affect Apache CloudStack: from 4.14.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
High [CVE-2026-50222] Missing Authorization, Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's Userdata reference APIs
Missing Authorization, Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's Userdata reference APIs. Several userdata-related APIs in Apache CloudStack, including deleteUserData, linkUserDataToTemplate, resetUserDataForVirtualMachine, deployVirtualMachine, and updateVirtualMachine, exhibit missing or insufficient access control validation, potentially allowing cross-tenant/cross-account access to userdata resources that belong to other tenants. This issue affects Apache CloudStack: from 4.18.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. The deleteCniConfiguration API, introduced in 4.21.0.0, also exhibits similar behaviour and lacks access validation. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
High [CVE-2026-59655] Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's OAuth authentication plugin while listing OAuth providers
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's OAuth authentication plugin while listing OAuth providers. This issue affects Apache CloudStack: from 4.19.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
High [CVE-2026-59657] Cleartext Storage of Sensitive Information vulnerability in Apache CloudStack with AsyncJob storage in the database
Cleartext Storage of Sensitive Information vulnerability in Apache CloudStack with AsyncJob storage in the database. This issue affects Apache CloudStack: from 4.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
High [CVE-2026-59780] Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's LDAP authentication plugin while listing LDAP providers
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's LDAP authentication plugin while listing LDAP providers. LDAP configurations can be listed by any authenticated user with access to the listLdapConfigurations API. By default, this API is available to all default roles. This issue affects Apache CloudStack: from 4.2.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
