CVE-2026-33430
HighSummary
Briefcase to narzędzie do konwertowania projektu Python na samodzielną aplikację natywną. W wersjach od 0.3.0 do 0.3.26, instalacja projektu jako MSI dla wszystkich użytkowników może prowadzić do utworzenia katalogu dziedziczącego uprawnienia katalogu nadrzędnego, co pozwala na modyfikację binariów przez użytkowników o niskich uprawnieniach.
Risk Assessment
Zagrożenie polega na tym, że użytkownik z niskimi uprawnieniami może zastąpić lub zmodyfikować binaria aplikacji, co w przypadku uruchomienia zmodyfikowanego pliku przez administratora skutkuje uruchomieniem go z podwyższonymi uprawnieniami.
Recommendation
Zaleca się aktualizację Briefcase do wersji 0.3.26 lub nowszej, aby skorzystać z poprawionych szablonów. Alternatywnie, można dodać poprawkę do istniejącego projektu Briefcase.

Bifrost registers MCP clients through its management API, where a stdio client is a command plus args that is started immediately upon client addition, with no MCP handshake required. Authentication is disabled by default (governance.auth_config.is_enabled=false), meaning every caller is treated as a local admin. A single unauthenticated POST /api/mcp/client is enough to run a program as the Bifrost process user (appuser on the official image).

- CVE-2026-90693Critical
A flaw has been found in D-Link DIR-878 120B05 impacting the SetWan3Settings function of the WAN Settings component. Manipulation of the Primary/Secondary argument causes a stack-based buffer overflow. Remote exploitation of the attack is possible.
- CVE-2026-90692Critical
A vulnerability was detected in D-Link DIR-878 120B05 affecting the SetDynamicDNSIPv6Settings function of the Dynamic DNS IPv6 Settings component. Manipulation of the IPv6Address/Hostname argument results in a stack-based buffer overflow. The attack may be launched remotely.
- CVE-2026-85192Critical
The Joomla Conditional Content extension (regularlabs.com) in versions < 8.0.0 allows authenticated, privileged remote code execution. Conditional Content Pro accepts inline PHP Condition Rules in article syntax, and in affected versions the PHP is passed to the Conditions evaluator without checking who authored the article. Joomla's normal Author text filter preserves the syntax, so publishing the article causes the code to run as the web-server process.
- CVE-2026-82787Critical
A missing authentication for critical function vulnerability exists in CPSL-08P1EN. If this vulnerability is exploited, an affected product may be operated by a remote attacker without authentication.

Original NVD description (English source)
Briefcase is a tool for converting a Python project into a standalone native application. Starting in version 0.3.0 and prior to version 0.3.26, if a developer uses Briefcase to produce an Windows MSI installer for a project, and that project is installed for All Users (i.e., per-machine scope), the installation process creates an directory that inherits all the permissions of the parent directory. Depending on the location chosen by the installing user, this may allow a low privilege but authenticated user to replace or modify the binaries installed by the application. If an administrator then runs the altered binary, the binary will run with elevated privileges. The problem is caused by the template used to generate the WXS file for Windows projects. It was fixed in the templates used in Briefcase 0.3.26, 0.4.0, and 0.4.1. Re-running `briefcase create` on your Briefcase project will result in the updated templates being used. As a workaround, the patch can be added to any existing Br
