- [#14566](https://github.com/withastro/astro/pull/14566) [`946fe68`](https://github.com/withastro/astro/commit/946fe68c973c966a4f589ae43858bf486cc70eb5) Thanks [@matthewp](https://github.com/matthewp)! - Fixes handling malformed cookies gracefully by returning the unparsed value instead of throwing
When a cookie with an invalid value is present (e.g., containing invalid URI sequences), `Astro.cookies.get()` now returns the raw cookie value instead of throwing a URIError. This aligns with the behavior of the underlying `cookie` package and prevents crashes when manually-set or corrupted cookies are encountered.
