Summary
Kwetsbaarheden verholpen in n8n workflow automation platform
Notes
The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten: n8n heeft meerdere kwetsbaarheden verholpen in het n8n workflow automation platform, specifiek in versies voor 1.123.55, 2.24.0, 2.25.7, 2.26.1 en 2.26.2.
Interpretaties: De kwetsbaarheden bereffen verschillende onderdelen van het n8n platform. Geuthenticeerde gebruikers met workflow bewerkingsrechten kunnen onder andere Content-Security-Policy (CSP) omzeilen via de Respond to Webhook node, en JavaScript injecteren via de Chat Trigger node. Verder kunnen zij API-tokens exfiltreren via de SecurityScorecard node en credentials van andere gebruikers benaderen, overschrijven of intrekken via de Dynamic Credentials feature. Ook kunnen gebruikers met editor toegang tot gedeelde workflows credentials van anderen inzien door onvoldoende eigendomcontroles. Ongeauthenticeerde aanvallers kunnen via de MicrosoftAgent365Trigger en StripeTrigger nodes valse payloads indienen, wat leidt tot uitvoering van workflows met kwaadaardige data.
Oplossingen: n8n heeft updates uitgebracht in versies 1.123.55, 2.24.0, 2.25.7, 2.26.1 en 2.26.2 om de genoemde kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
