Threat briefs

Portainer is vulnerable to an endpoint security bypass via Swarm service create/update, enabling non-admin users with access to a Docker Swarm endpoint to bypass `EndpointSecuritySettings` restrictions and gain elevated privileges such as configuring services with elevated Linux capabilities, disabling syscall filtering and AppArmor confinement, setting arbitrary sysctl values, and mounting arbitrary host paths.

Portainer versions 2.33.0 through 2.33.7, 2.39.0 through 2.39.1, and 2.40.0 through 2.40.9 are vulnerable to CVE-2026-44850, a bind-mount restriction bypass via the `HostConfig.Mounts` array allowing regular users to mount host paths into containers and potentially compromise the host filesystem.

Portainer is vulnerable to an arbitrary file read vulnerability due to Git symlink injection when deploying stacks from Git repositories, allowing authenticated users to read sensitive files accessible to the Portainer process.

Portainer versions 2.33.0 through 2.33.7 are vulnerable to an authorization bypass in the `kubeClientMiddleware` component, allowing users with valid Portainer sessions to bypass Kubernetes authorization checks and access Kubernetes API endpoints on environments that their role should not permit (CVE-2026-44882).

Portainer versions 2.33.0 through 2.33.7, 2.39.0 through 2.39.1, and 2.40.0 expose a missing authorization vulnerability (CVE-2026-44848) on the Docker plugin management endpoints, allowing a non-admin user with access to a Docker endpoint to install and enable arbitrary Docker plugins from any registry, ultimately leading to root privileges on the Docker host and unauthorized file system access.

A gym trainer in wger (<= 2.5) can escalate privileges to a gym manager by chaining calls to the trainer-login endpoint due to a flawed permission check, as tracked by CVE-2026-43978.

A SQL injection vulnerability (CVE-2026-44792) exists in n8n when using PostgreSQL and the Source Control feature, allowing an attacker with write access to the connected Git repository to inject malicious SQL via a crafted column name in a Data Table JSON file during a Source Control Pull.

CVE-2026-45732 describes a high-severity authorization bypass vulnerability in n8n's OAuth1 and OAuth2 credential reconnect endpoints, where insufficient permission checks allow a user with read-only access to overwrite OAuth tokens, potentially leading to data exfiltration and persistent takeover of shared integrations.

A denial-of-service vulnerability exists in Synapse where local authenticated users can cause CPU starvation, leading to request failures for other users (CVE-2026-45078).

FlowiseAI versions 3.1.1 and earlier are vulnerable to a privilege escalation due to missing authentication and permission checks on the OpenAI Assistants Vector Store CRUD endpoints, allowing any authenticated user to create, modify, upload files to, and delete vector stores and files, regardless of their assigned permissions.

FlowiseAI is vulnerable to a mass assignment vulnerability in the Assistant controller/service allowing an attacker, authenticated as a member of one workspace, to move an assistant (including configurations, instructions, tools and credentials) to another workspace by overwriting the `workspaceId` and `id` fields in the request body, leading to cross-workspace data takeover and IDOR.

FlowiseAI is vulnerable to cross-workspace data takeover due to mass assignment in the CustomTemplate controller, allowing an attacker to move templates to other workspaces by overwriting the `workspaceId` via API request.

FlowiseAI is vulnerable to a mass assignment vulnerability via `Object.assign(entity, body)` which allows a client-controlled `workspaceId` to be overwritten on the Dataset entity, leading to cross-workspace data takeover and IDOR.

FlowiseAI is vulnerable to a mass assignment vulnerability in the DatasetRow controller/service, allowing an authenticated attacker to overwrite the `workspaceId` and `id` of a DatasetRow entity, leading to cross-workspace data takeover and IDOR.

FlowiseAI is vulnerable to a mass assignment vulnerability (fixed in PR 6050) that allows authenticated users to move Evaluation entities between workspaces by overwriting the `workspaceId` field via API request, leading to unauthorized data access.

FlowiseAI is vulnerable to a mass assignment vulnerability in the Evaluator controller/service, where an attacker can manipulate the `workspaceId` during evaluator creation or updates, leading to cross-workspace data takeover and IDOR.

An authenticated user with workflow creation/modification permissions in n8n can achieve remote code execution (RCE) via global prototype pollution in the HTTP Request node due to an unvalidated pagination parameter, as tracked by CVE-2026-44789.

An authenticated user with workflow creation or modification permissions can inject CLI flags into the Git node's Push operation, leading to arbitrary file read on the n8n server; patched in versions 1.123.43, 2.20.7, and 2.22.1, and tracked as CVE-2026-44790.

An authenticated n8n user with workflow creation privileges can bypass a previous patch for XML node prototype pollution, potentially leading to remote code execution on the n8n host when combined with other nodes; patched in versions 1.123.43, 2.20.7, and 2.22.1.

wger 2.5 and earlier is vulnerable to CVE-2026-43977, an Insecure Direct Object Reference (IDOR) vulnerability that allows any authenticated user to read another user's private workout session notes, exercise history, and training statistics by accessing the `/logs/` and `/stats/` actions on a public template routine they do not own.

This rule detects allowed updates to Kubernetes pods/ephemeralcontainers subresource by non-system identities, which can be abused for privilege escalation, lateral movement, or persistence by injecting tooling into running pods.

Multiple vulnerabilities in Cisco Catalyst SD-WAN Manager could allow a remote attacker to gain access to sensitive information, elevate privileges, or gain unauthorized access to the application.

MongoDB published a security advisory to address CVE-2026-8053, an undefined behavior vulnerability when inserting data with duplicate field names into timeseries collections, affecting versions 5.0.0 through 8.3.1.

Detects when the AmazonEKSClusterAdminPolicy or AmazonEKSAdminPolicy is associated with a principal via the EKS Access Entries API, effectively granting full cluster-admin access and enabling potential privilege escalation and persistence.

Successful Amazon EKS Access Entries API operations that create, update, attach, detach, or delete authentication mappings between IAM principals and the cluster, potentially indicating persistence or privilege escalation are detected.

This rule detects modifications to the aws-auth ConfigMap in Amazon EKS clusters, enabling attackers to grant cluster-admin access by mapping AWS IAM roles to the system:masters group, achieving persistence and privilege escalation.

Vvveb before 1.0.8.3 is vulnerable to unrestricted file upload, allowing super_admin users to execute arbitrary PHP code by uploading a malicious plugin ZIP file containing PHP code which is then accessible via HTTP requests.

Vvveb before version 1.0.8.3 is vulnerable to an uncontrolled recursion vulnerability in the admin controller dispatch cycle that allows a low-privilege attacker to cause denial of service by exhausting PHP memory.

Siemens SIPROTEC 5 devices are vulnerable to session hijacking (CVE-2024-54017) due to the use of insufficiently random numbers in session identifier generation, potentially allowing an unauthenticated remote attacker to brute-force a valid session and gain unauthorized read access.

Siemens SIMATIC HMI Unified Comfort Panels before V21.0 are vulnerable to unauthenticated access via the help link and Control Panel (CVE-2026-27662), potentially leading to unauthorized configuration changes and discovery of backdoors.
