CVE-2026-72836

FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem confirmed on Windows/NTFS, two self-registered usernam...

CVE-2026-72829

The Grav API plugin getgrav/grav-plugin-api before 1.0.13 contains an API-key scope-cap bypass in UsersController's create and update methods. These methods enforce the scope cap only for api.users.write, but gate super-privilege grants on a bare isSuperAdmin check that reads access.api.super...

CVE-2026-72828

Grav Plugin API getgrav/grav-plugin-api before 1.0.13 fails to enforce API-key scope caps in InvitationsController. The strip-super and accept-groups decisions are gated on a bare isSuperAdmin check rather than a scope-aware permission check, so a least-privilege API key scoped to api.users.write...

CVE-2026-72833

The Grav API plugin getgrav/grav-plugin-api versions = 1.0.6 and = 1.0.11 contain a privilege escalation vulnerability. A scoped API key minted on a super-admin account bypasses its declared scope cap on four isSuperAdmin-gated write endpoints in GroupsController, AccountsConfigController,...

CVE-2026-72830

Grav API plugin versions before 1.0.13 fail to enforce API key scope caps in ConfigController super-scope gates, allowing scoped keys to write scheduler configuration. The scope cap is applied only inside requirePermission, while the scheduler and backups gates use a bare isSuperAdmin check that...

CVE-2026-72825

The getgrav/grav-plugin-api plugin before 1.0.13 contains an API-key scope cap bypass in the POST /reports/twig-content/allowlist endpoint ReportsController. The endpoint enforces requirePermission'api.config.write' followed by a bare isSuperAdmin check instead of requireSuper. Because isSuperAdm...

CVE-2026-72823

The Grav API plugin getgrav/grav-plugin-api before 1.0.13 contains an API-key scope cap bypass in DemoController. Its private requireSuper method checks isSuperAdmin and returns early before invoking requirePermission, so the apikeyscopes cap enforced only in requirePermission is skipped. As a...

CVE-2026-72826

The getgrav/grav-plugin-api plugin before 1.0.13 fails to validate that the scopes of a newly created API key are a subset of the caller's scopes in createApiKey. The self-target path of requireApiKeyPermission requires only the baseline api.access scope, and the new key's scopes are read directl...

CVE-2026-72822

The getgrav/grav-plugin-api Composer package before 1.0.13 affected = 1.0.12 fails to enforce API key scope caps on the disable2fa endpoint. Unlike the sibling generate2fa endpoint, disable2fa authorizes the admin non-self path solely via ACL reads isSuperAdmin/hasPermission and never invokes...

CVE-2026-72837 File Browser before 2.63.20 Privilege Escalation via Proxy Authentication

File Browser versions before 2.63.20 fail to honor the createUserDir isolation in proxy and hook authentication auto-provisioning paths. Attackers with valid upstream-authenticated credentials can read, modify, delete, and share files belonging to other users by exploiting the server root scope...

CVE-2026-72836

FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem confirmed on Windows/NTFS, two self-registered usernam...

CVE-2026-72836 FileBrowser before 2.63.19 Case Sensitivity Authentication Bypass

FileBrowser before 2.63.19 does not account for case-insensitive filesystems when checking home directory ownership during self-registration. When Signup and CreateUserDir are enabled and FileBrowser's root is on a case-insensitive filesystem confirmed on Windows/NTFS, two self-registered usernam...

CVE-2026-72833 Grav 1.0.6 through 1.0.11 Privilege Escalation via Scoped API Keys

The Grav API plugin getgrav/grav-plugin-api versions = 1.0.6 and = 1.0.11 contain a privilege escalation vulnerability. A scoped API key minted on a super-admin account bypasses its declared scope cap on four isSuperAdmin-gated write endpoints in GroupsController, AccountsConfigController,...

CVE-2026-72833

The Grav API plugin (getgrav/grav-plugin-api) versions 1.0.6–1.0.11 contain a privilege-escalation vulnerability. A scoped API key minted on a super-admin account bypasses the scope cap on four isSuperAdmin()-gated write endpoints (GroupsController, AccountsConfigController, PreferencesController...
