Title
Electron: nodeIntegrationInWorker not correctly scoped in shared renderer processes
Summary
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0, the nodeIntegrationInWorker webPreference was not correctly scoped in all configurations. In certain process-sharing scenarios, workers spawned in frames configured with nodeIntegrationInWorker: false could still receive Node.js integration. Apps are only affected if they enable nodeIntegrationInWorker. Apps that do not use nodeIntegrationInWorker are not affected. This issue has been patched in versions 38.8.6, 39.8.4, 40.8.4, and 41.0.0.

Title
Lack of isolation in mcp-run-python leads to MCP server takeover
Summary
The Python code being run by 'runPython' or 'runPythonAsync' is not isolated from the rest of the JS code, allowing any Python code to use the Pyodide APIs to modify the JS environment. This may result in an attacker hijacking the MCP server - for malicious purposes including MCP tool shadowing. Note - the "mcp-run-python" project is archived and unlikely to receive a fix.

Title
Cisco NX-OS Software Python Sandbox Escape Vulnerability
Summary
A vulnerability in the Python interpreter of Cisco NX-OS Software could allow an authenticated, local attacker with low privileges to escape the Python sandbox and gain unauthorized access to the underlying operating system of an affected device.
This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by manipulating specific functions within the Python interpreter. A successful exploit could allow an attacker to escape the Python sandbox and execute arbitrary commands on the underlying operating system with the privileges of the authenticated user.

Title
Cross-namespace traffic interception via incorrect route precedence ordering in AWS Load Balancer Controller
Summary
Incorrect behavior order in the Gateway API listener-rule generation in Amazon AWS Load Balancer Controller before 3.4.2 might allow an authenticated remote user to intercept, spoof, or deny another namespace's gRPC traffic on a shared Gateway via a crafted HTTPRoute resource.
To mitigate this issue, users should upgrade to version 3.4.2.

CVE-2026-5600 (GCVE-0-2026-5600)
Vulnerability from cvelistv5 – Published: 2026-04-08 12:24 – Updated: 2026-04-08 16:03

Summary
A new API endpoint introduced in pretix 2025 that is supposed to
return all check-in events of a specific event in fact returns all
check-in events belonging to the respective organizer. This allows an
API consumer to access information for all other events under the same
organizer, even those they should not have access to.
These records contain information on the time and result of every ticket scan as well as the ID of the matched ticket. Example:
{
"id": 123,
"successful": true,
"error_reason": null,
"error_explanation": null,
"position": 321,
"datetime": "2020-08-23T09:00:00+02:00",
"list": 456,
"created": "2020-08-23T09:00:00+02:00",
"auto_checked_in": false,
"gate": null,
"device": 1,
"device_id": 1,
"type": "entry"
}
An unauthorized user usually has no way to match these IDs (position) back to individual people.

Title
Keycloak: keycloak: replay of action tokens via improper handling of single-use entries
Summary
A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an attacker to delete arbitrary single-use entries, which can enable the replay of consumed action tokens, such as password reset links. This could lead to unauthorized access or account compromise.

Title
Keycloak: keycloak: privilege escalation via forged authorization codes due to singleuseobjectprovider isolation flaw
Summary
A flaw was found in Keycloak. The SingleUseObjectProvider, a global key-value store, lacks proper type and namespace isolation. This vulnerability allows an unauthenticated attacker to forge authorization codes. Successful exploitation can lead to the creation of admin-capable access tokens, resulting in privilege escalation.

Mitigation
Architecture and Design
Break up privileges between different modules, objects, or entities. Minimize the interfaces between modules and require strong access control between them.
