Technical description

Python Social Auth is a social authentication/registration mechanism. Prior to version 5.0.0, the Vend OAuth2 backend used only the numeric Vend user_id as the social-auth UID. When multiple Vend shops authenticate through the same application, users from different shops with the same internal Vend user ID could collide in the social-auth association table. A user from one shop could then be authenticated as the local account previously associated with the same numeric user ID from another shop. The issue affects applications using the Vend OAuth2 backend with more than one Vend shop. Version 5.0.0 patches the issue.

——13Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy normally matches the raw request path, while servlet backends such as Apache Tomcat strip semicolon matrix parameters from each path segment before resolving the resource. Envoy's ignore_path_parameters_in_path_matching option instead truncates at the first semicolon and still does not match per-segment backend behavior. A remote client can use a parameterized protected segment, or a parameter on an earlier segment, to make Envoy select an unprotected fallback while the backend resolves the protected resource. The relevant scope boundary is that the bypass requires both a path-based Envoy decision and a backend that strips semicolon parameters per segment. This issue is fixed in versions 1.36.10, 1.37.6, 1.38.4, and 1.39.1.2d CVE-2026-925795.4 MED

——11The MyHome Core plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 4.4.5. This is due to missing authorization in the send_link() AJAX handler and improper token validation in the activate() function. This makes it possible for unauthenticated attackers to generate an activation token for an unconfirmed user account and obtain a valid authentication cookie for that account, including administrators. Successful exploitation requires the MyHome theme to be configured in legacy/WPBakery mode with frontend registration and confirmation email enabled, and the target account must not already have the myhome_agent_confirmed user meta set.26d
