CVE-2024-47885Public exploitNetwork attack vector

Cross-site scripting via clobbered document.scripts lookup

Published Oct 14, 2024 · Updated Oct 15, 2024

Cross-site scripting in Astro 3.0.0 through 4.16.0 allows context-dependent attackers to execute script via stored scriptless HTML. The client-side router iterates document.scripts, which named DOM access can replace with attacker-controlled elements, then copies their innerHTML into a new script element. Exploitation requires ViewTransitions, stored HTML with unsanitized name attributes, and user navigation that triggers a page transition.
