CVE-2026-57481: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in parse-community parse-server
A vulnerability in parse-community parse-server prior to versions 8.6.83 and 9.9.1-alpha.13 allows a LiveQuery subscriber to receive object field values they are not authorized to read. This occurs when a single save operation changes both an object field and the subscriber's ACL read access, causing leave and enter events to include incorrect object state information. The issue is fixed in versions 8.6.83 and 9.9.1-alpha.13.
AI Analysis
Technical Summary
CVE-2026-57481 is an information exposure vulnerability (CWE-200) in parse-community's parse-server. Before versions 8.6.83 and 9.9.1-alpha.13, a LiveQuery subscriber could observe object field values without proper authorization if a save simultaneously modified the object field and the subscriber's ACL read permissions. This happened because the leave and enter events sent to the subscriber contained an incorrect snapshot of the object's state. The vulnerability is resolved in the specified fixed versions.
Potential Impact
Unauthorized actors subscribing to LiveQuery could receive sensitive object field data they should not have access to, potentially leading to information disclosure. The CVSS 4.0 base score is 2.3, indicating a low severity impact with network attack vector and low complexity.
Mitigation Recommendations
Upgrade parse-server to version 8.6.83 or later, or 9.9.1-alpha.13 or later to apply the fix for this vulnerability. No other mitigation is indicated by the vendor advisory.
