Descripción técnica

Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments. From 2.33.0 to before 2.33.8, 2.39.2, and 2.41.0, Portainer offers an environment-level Disable bind mounts for non-administrators security setting that blocks regular users from binding host paths into containers they create through the Portainer-mediated Docker API. The check that enforces this setting only inspected the legacy HostConfig.Binds array on the container-create proxy and never looked at the equivalent HostConfig.Mounts array. Any authenticated user with rights to create containers on a Docker environment where the restriction is enabled could submit a bind-typed entry under HostConfig.Mounts and mount any host path into their container. This vulnerability is fixed in 2.33.8, 2.39.2, and 2.41.0.

CVE-2026-49989—

———CrateDB is a distributed SQL database. Prior to versions 6.2.8 and 6.3.2, any authenticated user can read or delete any blob whose SHA-1 digest they know, and can plant new blobs unconditionally, in any blob table, regardless of `GRANT`s. CrateDB has two ways to access blob storage: SQL (`SELECT ... FROM blob.<table>` and friends) and the blob HTTP API (`GET|PUT|DELETE /_blobs/{table}/{digest}`). The SQL path goes through `AccessControl`, which is what enforces privilege grants; that's why `SELECT digest FROM blob.secret_blobs` fails for a user who has no grants on the table. The HTTP path authenticates the request but never asks `AccessControl` whether the authenticated user is allowed to touch the table. So a user with no grants gets `MissingPrivilegeException` from SQL and `200 OK` plus the blob bytes from `GET /_blobs/secret_blobs/<digest>`. Deployments that don't use `BLOB TABLE` are unaffected. Authentication itself still works; the bug is strictly that being authenticated as anyone is treated as sufficient for any blob op. Versions 6.2.8 and 6.3.2 fix the issue.5h CVE-2026-730495.8 MED

———SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getAttributeViewBacklinks endpoint that consults the forbidden access list instead of the visibility list when filtering backlinks. Anonymous readers can supply a publicly visible database row identifier to discover hidden-tier documents that reference it, receiving the database name, row title, and document path of hidden documents.10h CVE-2026-728597.7 ALT

———Budibase versions 3.39.4 before 3.40.0 contain an authorization regression in the S3 attachment upload endpoint that allows BASIC users to obtain S3 PutObject presigned URLs by sending POST requests to the attachments endpoint. The route was changed from a BUILDER permission check to a TABLE/WRITE check, which BASIC users hold by default. Attackers can specify arbitrary S3 buckets in the request body to generate presigned URLs for writing to any bucket accessible by the stored IAM credentials, enabling unauthorized file uploads.7h CVE-2026-728318.8 ALT

———The Flex Objects plugin (through 1.4.6, tested with Grav 2.0.11) contains an incorrect authorization vulnerability in its Flex Objects API. FlexApiController::update() checks only the general Flex directory permission and does not apply the additional target/field/super-admin checks enforced by the dedicated Users and Groups API controllers. An authenticated account with api.access, admin.login, and users.update permissions (but without api.users.write or admin.super) can use the generic /api/v1/flex-objects/user-accounts endpoint to change a super administrator's password, or the /api/v1/flex-objects/user-groups endpoint to grant its group admin.super, resulting in full site takeover. Fixed in Flex Objects 1.4.7.10h CVE-2026-738418.8 ALT

———OpenChoreo is a complete, open-source developer platform for Kubernetes. From 1.2.0-rc.1 until 1.2.0, internal/openchoreo-api/api/handlers/exec.go and internal/openchoreo-api/api/handlers/wirelogs.go authorize component:exec and wirelogs:view using the caller-supplied project query parameter instead of comp.Spec.Owner.ProjectName, allowing a user with a project-scoped grant to execute commands in and read wirelogs from components owned by other projects in the same namespace. This vulnerability is fixed in 1.2.0.5h CVE-2026-733058.8 ALT

———Budibase is an open-source low-code platform. Prior to 3.39.24, POST /api/public/v1/roles/assign called validateGlobalRoleUpdate without checking appBuilder.appId or role.appId in packages/server/src/api/controllers/public/globalRoleValidation.ts. An app-scoped builder could scope the request to an app they control and then grant themselves builder access or an arbitrary role in another app, exposing that app data, datasource configuration, and automations. This issue is fixed in version 3.39.24.1d
