CVE-2026-88893Network attack vector

Unauthenticated share lookup information disclosure

Published Sep 10, 2026 · Updated Sep 10, 2026

Information disclosure in OpenPanel share lookup procedures allows remote attackers with a share link to retrieve protected report data. The procedures return stored argon2id password hashes and complete report definitions without enforcing the access controls that protect those records. Possession of a valid share link is required, and the exposed event names, filters, and breakdown dimensions reveal business intelligence while the hashes enable offline password cracking.
