Description

This security bulletin contains information about 1 vulnerability.


1) Information disclosure (CVE-ID: CVE-2026-57481)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improper access control in LiveQuery enter and leave event handling when processing a save that changes both object field values and the subscriber's ACL read access. A remote user can subscribe to object updates and trigger or receive a crafted state change to disclose sensitive information.

The disclosure is limited to the single object affected by that save and only to the subscriber whose read access changed. Master-key subscribers are not affected.


Remediation

Install update from vendor's website.
