CVE-2024-52511Network attack vector

Unauthorized row insertion via unchecked object identifiers

Published Nov 15, 2024 · Updated Nov 15, 2024

Authorization bypass in Nextcloud Tables before 0.8.0 allows remote authenticated users to insert rows into inaccessible tables via crafted IDs. The row-creation endpoints accepted attacker-supplied tableId or viewId values without enforcing CREATE permission on the identified object. A logged-in Tables user can modify data in a table or view that has not been shared with that account; no availability impact is reported.
