Descrição técnica

Kyverno from 1.19.1 before 1.19.2 contains a namespace isolation bypass in APICall Fetch() in pkg/engine/apicall/apiCall.go because path.Clean treats '?' as a path character, letting the namespace regex match segments inside the query string. Users who can create namespaced policies can supply a URLPath like /api/v1/nodes?x=/namespaces/default/ that passes validation while client-go requests the cluster-scoped endpoint, reading resources outside their namespace.

——0SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to 7.15.2 and 8.10.2, the V8 module API exposes CRUD operations for administrator-only modules to any authenticated OAuth2 user. The affected flow begins at /Api/V8/module and uses ACLRoles, ACLActions, and Administration to carry attacker-controlled data or authorization state into the security-sensitive operation. A low-privileged user can create roles, change ACL levels, bind elevated roles, and alter global configuration to obtain administrator-equivalent control of CRM data and behavior. This issue is fixed in versions 7.15.2 and 8.10.2.7h CVE-2026-774398.8 ALT

——0Immich is a self-hosted photo and video management solution. Prior to 3.0.3, an authenticated user with editor access to a shared album can change the existing owner's role because album member role updates do not protect the owner from modification. By demoting the owner and then promoting themselves, an editor can take ownership of the album, remove the original owner, and delete the album. This vulnerability is fixed in version 3.0.3.8h CVE-2026-1181938.8 ALT

——10The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.19.1 via the `donor_default_user_role` parameter. This is due to the `sanitize_option_donor_default_user_role()` function applying only a narrow literal check against the string `'administrator'` rather than enforcing the plugin's own `give_get_donor_safe_user_roles()` allowlist on save, and due to the `give_core_settings_import_callback()` AJAX handler writing imported JSON directly into the `give_settings` option via `update_option()` without invoking the sanitize filter at all. This makes it possible for authenticated attackers with the GiveWP Manager role (holding the `manage_give_settings` capability) and above to configure donor registration to assign privileged WordPress roles — up to and including Administrator via the import path — to every new donor account created through the platform. Via the settings save path, the Administrator role is blocked but any other elevated role (Editor, Author, etc.) is accepted; via the Tools › Import JSON path, the sanitize filter is bypassed entirely, allowing the Administrator role itself to be stored and subsequently applied to all newly registered donor accounts.21h CVE-2026-1223139.9 CRÍ

——7Kyverno from 1.17.0 before 1.19.2 contains a privilege escalation vulnerability that allows namespace-scoped tenants to modify resources in other namespaces through NamespacedMutatingPolicy targetMatchConstraints.expression CEL output lacking namespace checks. Attackers can emit a literal target such as another tenant's RoleBinding, which the cluster-wide background controller then mutates to add attacker subjects or alter Roles, NetworkPolicies, and ConfigMaps.11h CVE-2026-1223029.8 CRÍ

——6Kyverno before 1.19.2 contains a privilege escalation vulnerability that allows namespace admins to create resources beyond their RBAC because generate-rule admission checks verify the controller's permissions, not the author's. Attackers can create a namespaced Policy with generate rules targeting other namespaces or cluster-scoped kinds, making the background controller create or clone resources cluster-wide.11h CVE-2026-1220166.3 MÉD

——6A vulnerability was determined in yangzongzhuan RuoYi-Vue up to 3.9.2. This issue affects the function SysPermissionService.getMenuPermission of the file SysPermissionService.java of the component Permission Service. This manipulation of the argument perms causes improper privilege management. The attack may be initiated remotely. The vendor was contacted early about this disclosure but did not respond in any way.1d
