Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to invalidate the cache when a user account is converted to a bot which allows an attacker to login to the bot exactly one time via normal credentials.

Mattermost versions 10.5.x <= 10.5.1, 9.11.x <= 9.11.9 fail to check if a file has been deleted when creating a bookmark which allows an attacker who knows the IDs of deleted files to obtain metadata of the files via bookmark creation.

### Summary gorilla/csrf is vulnerable to CSRF via form submission from origins that share a top level domain with the target origin. ### Details gorilla/csrf does not validate the Origin header against an allowlist. Its executes its validation of the Referer header for cross-origin requests only when it believes the request is being served over TLS. It determines this by inspecting the `r.URL.Scheme` value. However, this value is never populated for "server" requests [per the Go spec](https://pkg.go.dev/net/http#Request), and so this check does not run in practice. ``` // URL specifies either the URI being requested (for server // requests) or the URL to access (for client requests). // // For server requests, the URL is parsed from the URI // supplied on the Request-Line as stored in RequestURI. For // most requests, fields other than Path and RawQuery will be // empty. (See [RFC 7230, Section 5.3](https://rfc-editor.org/rfc/rfc7230.html#section-5.3)) // // For client r...

### Summary Access token from query string is not redacted and is potentially exposed in system logs which may be persisted. ### Details The access token in `req.query` is not redacted when the `LOG_STYLE` is set to `raw`. If these logs are not properly sanitized or protected, an attacker with access to it can potentially gain administrative control, leading to unauthorized data access and manipulation. ### PoC 1. Set `LOG_LEVEL="raw"` in the environment. 2. Send a request with the `access_token` in the query string. 3. Notice that the `access_token` in `req.query` is not redacted. ### Impact It impacts systems where the `LOG_STYLE` is set to `raw`. The `access_token` in the query could potentially be a long-lived static token. Users with impacted systems should rotate their static tokens if they were provided using query string.

A newly created inetpub folder turns out to be part of a Microsoft update against a vulnerability tracked as CVE-2025-21204

Millions of scam text messages are sent every month. The Chinese cybercriminals behind many of them are expanding their operations—and quickly innovating.

Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to restrict certain operations on system admins to only other system admins, which allows delegated granular administration users with the "Edit Other Users" permission to perform unauthorized modifications to system administrators via improper permission validation.

An email sent by the Department of Homeland Security instructs people in the US on a temporary legal status to leave the country. But who the email actually applies to—and who actually received it—is far from clear.

## Summary `jupyter-remote-desktop-proxy` was meant to rely on UNIX sockets readable only by the current user since version 3.0.0, but when used with TigerVNC, the VNC server started by `jupyter-remote-desktop-proxy` were still accessible via the network. This vulnerability does not affect users having TurboVNC as the `vncserver` executable. ## Credits This vulnerability was identified by Arne Gottwald at University of Göttingen and analyzed, reported, and reviewed by @frejanordsiek.
