CVE-2026-86782Network attack vector

Contributor cross-user content modification via unchecked chart IDs

Published Sep 11, 2026 · Updated Sep 11, 2026

Missing authorization in Themeisle Visualizer before 4.0.6 allows remote authenticated users to modify posts and pages through chart actions. Chart-building actions accept attacker-selected post or page identifiers without checking that the Contributor owns or may edit the referenced object. Contributor access is sufficient to publish, rename, or overwrite another user's content, including private drafts.
