No sign of exploitation. No public exploitation artifact known so far.
Nextcloud Tables exposes filter criteria details to read-only users who shouldn't see them. This leaks information about how data is being filtered, which could reveal sensitive details about the database structure or filtered content.
CWE-1230 (Broken Sensitive Data Masking) allows read-only users in Nextcloud Tables to access view filter metadata through the ViewService, bypassing intended data protection controls. The vulnerability exists in versions 0.8.0 through 1.0.3; affected systems require upgrade to 1.0.4 or 2.0.0 to remediate the information disclosure.
In the same product, most dangerous first.
