CVE-2024-47764: cookie accepts cookie name, path, and domain with out of bounds characters
### Impact The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. 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`. A similar escape can be used for `path` and `domain`, which could be abused to alter other fields of the cookie. ### Patches Upgrade to 0.7.0, which updates the validation for `name`, `path`, and `domain`. ### Workarounds Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input. ### References * https://github.com/jshttp/cookie/pull/167
