Technical description

When a particular authentication mode is configured, the reverse proxy forwards requests for a bundled third-party administrative interface directly to that interface without applying the gateway's own authentication requirement first. All access control for this administrative interface, which manages the credential store used to gate every other service in the deployment, is delegated entirely to that third-party interface's own login mechanism. Any authentication weakness in that bundled interface would compromise the credential store protecting the rest of the deployment.

———Mousehole is a background service to update a seedbox IP for MAM and web app to manage it. Prior to version 0.4.05, Mousehole's HTTP/WebSocket management boundary is reachable without application-layer authentication or browser/LAN provenance checks. The service stores a MyAnonamouse (MAM) session cookie in state and reuses the same cookie-bearing serialization for persisted state, public API responses, and WebSocket state updates. Any client that can reach the published Mousehole port can read cookie-bearing state, connect to WebSocket state updates, replace the stored cookie, or force MAM update side effects. The deployment examples publish port 5010 broadly with Docker's `5010:5010` syntax, which can make the issue reachable on mixed-trust LAN/VPN interfaces. Version 0.4.0 patches the issue.6h CVE-2026-539529.8 CRI

———GetSimple CMS is a content management system (CMS), and GetSimple CMS CE is the community edition of that CMS. A logic flaw in GetSimple CMS (v3.4.0a and below) and GetSimpleCMS-CE (v3.3.22 and below) allows unauthenticated attackers to create a new administrator account. The application features an automated security control designed to delete the sensitive `admin/setup.php` file post-installation. However, this control is neutralized by a self-exclusion bug within the deletion logic, leaving the setup script accessible for unauthorized account creation even after a legitimate installation is completed. As of time of publication, no known patched versions are available.7h CVE-2026-892635.3 MED

———MoguBlog through 6.2 fails to authenticate requests to the /web/comment/closeEmailNotification endpoint, allowing unauthenticated attackers to disable email notifications for arbitrary users. Remote callers can modify the startEmailNotification flag in Redis cache for any user identifier to suppress reply notifications without authorization.10h CVE-2026-892616.5 MED

———MoguBlog through 6.2 exposes Elasticsearch index management endpoints in the mogu_search service without authentication, allowing remote attackers to delete, recreate, or alter the blog search index. Attackers can invoke POST endpoints to wipe the entire search index, delete specific documents, or inject malicious index entries, causing search functionality to return incorrect or no results.7h CVE-2026-8046210.0 CRI
