CVSSv4: 5.3 [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]


The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to improper access control in FileWebService when handling authenticated web service queries for folder identifiers. A remote user can query the service with valid credentials and enumerate files and sub-folders of arbitrary folders by ID to disclose sensitive information.

Only metadata is exposed, including fields such as identifiers, types, and names; file contents are not disclosed.


2) Use of hard-coded credentials (CVE-ID: CVE-2026-33266)

CWE-ID: CWE-798 - Use of Hard-coded Credentials

The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to use of a hard-coded cryptographic key in remember-me cookie encryption in Apache OpenMeetings when processing a stolen remember-me cookie from a logged-in user. A remote user can use a stolen cookie encrypted with the default key to disclose sensitive information.
