CVE-2022-42967Public exploitNetwork attack vector

Code execution via outdated DOMPurify filtering

Published Jan 11, 2023 · Updated Apr 8, 2025

Cross-site scripting in all versions of Caret allows attackers to execute code when a crafted Markdown file is opened in preview mode. The getMarkdownHtmlElement function assigns document data sanitized by an outdated DOMPurify release to an Electron renderer element through innerHTML, allowing a filtering bypass to reach an event handler. Execution requires a user to open the malicious file with preview mode enabled, after which attacker-supplied code can launch arbitrary processes with the user's privileges.
