Descripción técnica

DotVVM is an open source MVVM framework for web applications. Prior to 4.2.11, 4.3.15, and 5.0.0-preview09-final, AuthorizeActionFilter performs no authorization because its explicit ICommandActionFilter.OnCommandExecutingAsync, IViewModelActionFilter.OnViewModelCreatedAsync, and IPresenterActionFilter.OnPresenterExecutingAsync implementations return completed tasks instead of invoking the corresponding checks. Applications relying on this filter can therefore expose protected commands, view models, or presenters to unauthorized requests without any special bypass technique. AuthorizeAttribute correctly implements the same interfaces and can be used as a workaround. This issue is fixed in versions 4.2.11, 4.3.15, and 5.0.0-preview09-final.

———A vulnerability has been found in DjangoCRM django-crm up to 1.2. This vulnerability affects the function BulkUpdateCasesView of the file backend/cases/bulk_views.py of the component Bulk Case Update. The manipulation leads to missing authorization. The attack is possible to be carried out remotely. Upgrading to version 1.3.0 is able to resolve this issue. The identifier of the patch is 799bb1210238f402c0c4948c8eedb6e61cd0c8d7. You should upgrade the affected component.6h CVE-2026-575706.5 MED

———backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.15 and 7.0.47, HasMany and MorphMany handling through attachManyRelation during CRUD create and update operations accepts submitted child primary keys without consistently restricting updates to records belonging to the current parent or permitted by the developer-defined relation scope. An authenticated low-privilege administrator who can edit a parent form exposing an affected multiple-relation field can cause unrelated child records to be reassigned, detached, nulled, or deleted across ownership or tenant boundaries. Exploitation requires related records that should not be attachable or removable by that administrator and the absence of additional application-level authorization around submitted relation values. This issue is distinct from earlier direct main-entity CRUD scoping fixes because it affects secondary models modified by relationship-saving logic. This issue is fixed in versions 6.8.15 and 7.0.47.6h CVE-2026-575797.5 ALT

———Alchemy is an open source content management system engine written in Ruby on Rails. Prior to 7.4.15, 8.0.15, 8.1.14, and 8.2.6, the unauthenticated GET /api/pages/nested endpoint implemented by Api::PagesController#nested in app/controllers/alchemy/api/pages_controller.rb returns an unfiltered page tree because it performs no authorization and does not scope descendants by the caller's ability. Anonymous callers can retrieve restricted and unpublished page metadata that the sibling show action denies. When elements=true is supplied, PageTreeSerializer also returns element and ingredient content from restricted pages because PageTreePreloader and the serializer do not apply an ability check to those records. This issue is fixed in versions 7.4.15, 8.0.15, 8.1.14, and 8.2.6.6h CVE-2026-571319.8 CRÍ

———PraisonAI is a multi-agent teams system. Prior to 4.6.58, praisonai.jobs.server.create_app mounts praisonai.jobs.router.create_router under /api/v1/runs without authentication or per-job authorization. Network clients can submit attacker-controlled prompts and agent configuration, list and read jobs, stream results, and cancel or delete other jobs, exposing service credentials and connected tool capabilities to unauthorized agent execution. This vulnerability is fixed in 4.6.58.7h CVE-2026-82437—

———Description The Logviewer offers `logs.users` and `logs.groups` so operators can control who may read log content. For daemon logs those settings were not applied: the access decision combined the "this is a daemon log" flag with the authorizer result in a way that discarded the authorizer's answer whenever the flag was set, and the daemon log page and download endpoints reached the handler without consulting an authorizer at all. Any user able to pass the configured servlet filter could therefore read `nimbus.log`, `supervisor.log` and the other daemon logs on every reachable node, which contain other tenants' topology names, owners and configuration fragments. The same advisory covers the log listing endpoints, which accepted a user argument and never applied it, so `/listLogs` and `/searchLogs` returned every tenant's topology and worker log file names regardless of the caller. That part is metadata only. There was no configuration that closed either behaviour. Mitigation Upgrade to 3.1.0, where the daemon log paths evaluate the same configured user and group lists that the worker log paths already used, and the listing endpoints filter by the requesting user. Users who cannot upgrade immediately should place the Logviewer behind a reverse proxy that restricts the daemon log endpoints, and should treat daemon log content as readable by any filter-authenticated user.

———Description `getNimbusConf` returned the complete daemon configuration without redaction after only a user-level authorization check. Where the cluster is configured with them, that response includes `storm.zookeeper.auth.payload` and the keystore and truststore passwords for the Thrift, Netty and ZooKeeper TLS configuration. The project masks passwords elsewhere before display, so the omission here is inconsistent rather than intended. The UI endpoint `/api/v1/cluster/configuration` compounded this. It carried no `@AuthNimbusOp` annotation, and the authorization filter treated a missing annotation as "no gate required" and returned immediately, so the endpoint applied no per-user check at all and proxied the request under the UI daemon's own principal. Any user able to pass `ui.filter` therefore received the full configuration, including principals that Nimbus itself would have refused. Mitigation Upgrade to 3.1.0, where credential-bearing values are masked before the configuration is served and where every UI API endpoint must declare its authorization explicitly. Users who cannot upgrade immediately should place the UI behind an authenticating reverse proxy that restricts `/api/v1/cluster/configuration`, and should rotate the ZooKeeper authentication payload and any TLS keystore or truststore passwords that were reachable through it.
