CVE-2024-35236Public exploitNetwork attack vector

Browser code execution via scripted EPUB content

Published May 27, 2024 · Updated Aug 2, 2024

Cross-site scripting in Audiobookshelf before 2.10.0 allows attackers to execute JavaScript when a user opens a crafted EPUB. EpubReader.vue passes allowScriptedContent=true to epub.js, whose iframe sandbox also allows same-origin content, so embedded scripts escape the intended isolation. Opening the file is required; scripts run with the reader's browser access, and a highly privileged session can turn arbitrary file writes into server code execution.
