CVE-2026-34388
HighSummary
Fleet to oprogramowanie do zarządzania urządzeniami typu open source. W wersjach przed 4.81.0 występuje podatność na atak typu denial-of-service w punkcie końcowym gRPC Launcher, która pozwala uwierzytelnionemu hostowi na awarię całego procesu serwera Fleet poprzez wysłanie nieoczekiwanej wartości typu logu.
Risk Assessment
Podatność ta prowadzi do natychmiastowego zakończenia działania serwera, co zakłóca pracę wszystkich podłączonych hostów, rejestracji MDM oraz konsumentów API, co może poważnie wpłynąć na operacje organizacji.
Recommendation
Zaleca się aktualizację do wersji 4.81.0 lub nowszej, aby załatać tę podatność i zapewnić ciągłość działania serwera Fleet.

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).

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.

Original NVD description (English source)
Fleet is open source device management software. Prior to 4.81.0, a denial-of-service vulnerability in Fleet's gRPC Launcher endpoint allows an authenticated host to crash the entire Fleet server process by sending an unexpected log type value. The server terminates immediately, disrupting all connected hosts, MDM enrollments, and API consumers. Version 4.81.0 patches the issue.
