CVE-2026-81505Public exploitNetwork attack vectorHinoki check available

Cross-tenant credential disclosure via unscoped Source lookup

Published Sep 18, 2026 · Updated Sep 18, 2026

Broken object authorization in Convoy before 26.6.8 allows remote authenticated users to read other projects' Source records. Handler.GetSource authorizes the URL's project, but FindSourceByID ignores its projectID argument and queries only by source ID before returning the unredacted record. Access to any project or a project-scoped API key is sufficient to disclose another project's AMQP, Kafka, SQS, or Google PubSub credentials; the project-scoped list endpoint is unaffected.
