A flaw was found in Astro. The rendering engine fails to properly sanitize dynamic values placed inside script and style elements, mistakenly treating them as trusted markup. A remote attacker can exploit this issue by supplying crafted input that prematurely closes the tag and injects malicious code. Successful exploitation can lead to Cross-Site Scripting (XSS), allowing the execution of arbitrary web scripts in the user's browser session.
