AI Analysis
Technical Summary
Nextcloud's security-advisories component before version 2.7.2 contains an information disclosure vulnerability (CWE-200) that allows authenticated users to check whether arbitrary files are associated with approval workflows. This could reveal sensitive metadata about file approval states. The vulnerability has a CVSS 3.1 base score of 3.3, indicating low impact, and does not affect confidentiality beyond limited information exposure, nor does it impact integrity or availability. The flaw was patched in version 2.7.2.
Potential Impact
The vulnerability allows authenticated users to gain limited sensitive information about file approval workflows, which could potentially aid in reconnaissance but does not permit modification or disruption of data or services. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade Nextcloud to version 2.7.2 or later where this vulnerability has been fixed. Since this is not a cloud service, users must apply the update themselves. Patch status is confirmed by the vendor stating the issue is resolved in version 2.7.2.
