Information Disclosure in parse (CVE-2026-57481)
Summary
Vulnerability in parse (CVE-2026-57481). Risk of unauthorized operations or information disclosure. Exploitable via save. Mitigation: upgrade to 8.6.83, 9.9.1 or later.
Original description
The description as published by the source.
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.9.1-alpha.13 and 8.6.83, a LiveQuery subscriber could receive object field values they were not authorized to read when a single save changed both an object field and the subscriber's ACL read access, because leave and enter events included the wrong object state. This issue is fixed in versions 9.9.1-alpha.13 and 8.6.83.

CVE-2026-57481 (parse) — CWE-200
Attack surface: save / leave / enter
Patched: 8.6.83, 9.9.1 — apply immediately
Workaround: Do not change an object's field values and a subscriber's ACL read access in the same save on LiveQuery-enabled classes; perform the access-control change in a separate save before or after the content change.
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
