Last modified

CVE-2026-116801 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. Parse Server before 8.6.105 and 9.0.0 before 9.10.5-alpha.6 does not validate the owning object reference in $relatedTo relation queries, so supplying a query operator instead of an object ID bypasses the owning-object ACL check. A client with read access to at least one object of the owning class can disclose which readable objects are linked to owning objects it cannot read.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
