What is CVE-2026-116805?

OpenPanel versions prior to 3.0.0 are susceptible to an information disclosure vulnerability. This flaw allows read-level project members to access argon2id hashes of ingestion credentials through the client.list tRPC query. By supplying a project ID, an attacker can retrieve full Client rows, including sensitive secret columns. This can lead to unauthorized offline verification of these credentials without leaving audit trails, potentially exposing critical secrets.
