CVE-2026-116161 is a medium-severity flaw (CVSS 6.0) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
