10.0.x, and 9.4.x are not affected. It is, therefore, affected by a SQL injection vulnerability as referenced in the
SVD-2026-1001 advisory. A user that holds a role with the list_spl2_modules capability could use SQL injection in SPL2
module filtering to access data available through the affected REST API, including private SPL2 module definitions
belonging to other users. (CVE-2026-76270)
