CVE-2024-32468Network attack vector

Script execution via unsanitized generated documentation

Published Nov 25, 2024 · Updated Nov 25, 2024

Cross-site scripting in Deno before 1.42.0 allows remote authenticated users to execute script when generated HTML documentation is viewed. The deno_doc HTML generator places unescaped property, method, and enum names into pages and passes unsanitized search data to innerHTML. Exploitation requires crafted package input and a user to generate and view its documentation; script runs in the documentation page context.
