Parse Server LiveQuery subscription with invalid regular expression crashes server
상세
### Impact
A remote attacker can crash the Parse Server by subscribing to a LiveQuery with an invalid regular expression pattern. The server process terminates when the invalid pattern reaches the regex engine during subscription matching, causing denial of service for all connected clients.
### Patches
The fix validates regular expression patterns at subscription time, rejecting invalid patterns before they are stored. Additionally, a defense-in-depth try-catch prevents any subscription matching error from crashing the server process.
### Workarounds
Disable LiveQuery if it is not needed.
