Lifecycle Timeline
3DescriptionCVE.org
OpenPanel share lookup procedures fail to validate access controls and return password hashes and protected report definitions to unauthenticated callers. Attackers with a share link can retrieve argon2id password hashes and full report configurations including event names, filters, and breakdown dimensions for offline password cracking and business intelligence theft.
AnalysisAI
Unauthenticated information disclosure in OpenPanel (openpanel-dev/openpanel) exposes argon2id password hashes and full report configurations to any caller possessing a share link. The share lookup API endpoint fails to enforce access controls, returning sensitive account credentials and proprietary business intelligence data - event names, filters, and breakdown dimensions - without validating the caller's identity or authorization. …
