What is CVE-2026-119126?

A vulnerability in Parse Server releases prior to 8.6.106 and 9.0.0-alpha.7 allows attackers with write access to exploit mishandled dot notation keys containing null or undefined values. This issue can result in written data being stored although an error is returned, effectively bypassing critical afterSave triggers and LiveQuery events. Consequently, audit logging and notifications can be evaded, compromising data integrity and security. This vulnerability poses a significant risk to applications relying on Parse Server for data persistence and management.

Affected Version(s)

parse-server 9.0.0 < 9.10.5-alpha.7

parse-server 0 < 8.6.106

parse-server 9.10.5-alpha.7
