MEDIUM5.9EPSS 0.04%Parse Server LiveQuery subscription with invalid regular expression crashes server
發布日:2026/3/17修改日:2026/3/20
描述
### 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.
