Parse Server 9.0.0 before 9.10.5-alpha.4 LiveQuery Information Disclosure via $or Subscriptions
Impact
Parse Server versions 9.0.0 before 9.10.5-alpha.4 contain an information disclosure vulnerability in LiveQuery, allowing authenticated clients to receive other users' events. The vulnerability occurs due to the subscription hash omitting constraints next to a $or operator. This can lead to exposure of sensitive information, including session tokens usable for impersonation.

Original source description
Parse Server before 8.6.103 and 9.0.0 before 9.10.5-alpha.4 contains an information disclosure vulnerability in LiveQuery. Its subscription hash omits constraints next to a $or operator, including the _Session owner filter and beforeSubscribe constraints, so distinct subscriptions are grouped together. Authenticated clients subscribing with $or queries can receive other users' events, including session tokens usable for impersonation.
