CVE-2026-33664
HighSummary
Kestra to otwartoźródłowa platforma orkiestracji zdarzeń, której wersje do 1.3.3 renderują pola metadanych YAML dostarczane przez użytkownika bez odpowiedniej sanitizacji. Umożliwia to autorowi przepływu osadzenie dowolnego JavaScriptu, który jest wykonywany w przeglądarce każdego użytkownika, który przegląda lub wchodzi w interakcję z przepływem.
Risk Assessment
Ryzyko związane z tą podatnością polega na możliwości wykonania złośliwego kodu JavaScript w przeglądarkach użytkowników, co może prowadzić do kradzieży danych lub przejęcia sesji. Organizacje powinny być świadome, że atakujący mogą wykorzystać tę lukę do szkodliwych działań bez interakcji ze strony użytkownika.
Recommendation
Zaleca się aktualizację do najnowszej wersji Kestra, jeśli jest dostępna, oraz monitorowanie wszelkich działań związanych z bezpieczeństwem. Należy również rozważyć wprowadzenie dodatkowych środków ochrony, takich jak filtracja danych wejściowych.

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-2026-85192Critical
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.

Original NVD description (English source)
Kestra is an open-source, event-driven orchestration platform Versions up to and including 1.3.3 render user-supplied flow YAML metadata fields — description, inputs[].displayName, inputs[].description — through the Markdown.vue component instantiated with html: true. The resulting HTML is injected into the DOM via Vue's v-html without any sanitization. This allows a flow author to embed arbitrary JavaScript that executes in the browser of any user who views or interacts with the flow. This is distinct from GHSA-r36c-83hm-pc8j / CVE-2026-29082, which covers only FilePreview.vue rendering .md files from execution outputs. The present finding affects different components, different data sources, and requires significantly less user interaction (zero-click for input.displayName). As of time of publication, it is unclear if a patch is available.
