What is CVE-2026-44719?
CVE-2026-44719 is a medium-severity missing authorization vulnerability in mathesar-foundation mathesar, published on 15 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Mathesar is a web application that makes working with PostgreSQL databases both simple and powerful. From 0.2.0 to before 0.10.0, collaborators.list, tables.metadata.list, explorations.list, and forms.list accept a database_id without verifying that the requesting user was a collaborator on that database. An authenticated user on the same Mathesar installation could use these methods to view Mathesar-managed metadata for databases where they were not a collaborator. Depending on the database and features in use, exposed metadata could include collaborator mappings, table metadata, saved exploration metadata, and form metadata. For forms, the exposed metadata included form tokens. For public forms, possession of the token is equivalent to possession of the public form link, which allows submission to the form under the form’s configured PostgreSQL role. This vulnerability is fixed in 0.10.0.
Weakness: CWE-862
