GHSA-78w9-wwff-vxqc: OpenPanel before 3.0.0 Information Disclosure of Ingestion Secret Hashes via client.list

OpenPanel before 3.0.0 contains an information disclosure vulnerability that allows read-level project members to obtain argon2id hashes of ingestion credentials through the client.list tRPC query. Attackers can request client.list with a project ID and receive full Client rows including the secret column, enabling offline verification of leaked secrets without audit trails.
