CVE-2024-47764

Name of the Vulnerable Software and Affected Versions cookie versions prior to 0.7.0

Description The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie. For example, serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value) would result in "userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test", setting userName cookie to <script> and ignoring value.

Recommendations Upgrade to 0.7.0, which updates the validation for name, path, and domain. As a temporary workaround, avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input.
