CVE-2026-55069: CWE-916: Use of Password Hash With Insufficient Computational Effort in kestra-io kestra
Kestra is an open-source, event-driven orchestration platform. Prior to 1.3.24, this vulnerability exists in the BasicAuth authentication component of the Kestra OSS workflow orchestration platform. An attacker who gains read access to the PostgreSQL database can exploit SHA-512's high computation speed to recover the administrator password offline. In Kubernetes deployments, a successful crack further enables reading of the cluster ServiceAccount Token and all K8s Secrets, achieving vertical privilege escalation. This vulnerability is fixed in 1.3.24.
AI Analysis
Technical Summary
CVE-2026-55069 affects Kestra, an open-source orchestration platform, due to the use of SHA-512 hashing for passwords without sufficient computational cost, enabling offline password cracking if an attacker gains read access to the PostgreSQL database. This weakness exists in the BasicAuth authentication component prior to version 1.3.24. In Kubernetes environments, exploitation can escalate privileges by exposing the cluster ServiceAccount Token and all Kubernetes Secrets. The vulnerability is addressed in Kestra version 1.3.24.
Potential Impact
An attacker who obtains read access to the PostgreSQL database can exploit the fast SHA-512 hash to recover the administrator password offline. In Kubernetes deployments, this can lead to disclosure of the cluster ServiceAccount Token and all Kubernetes Secrets, enabling vertical privilege escalation. Confidentiality and integrity of the system are severely impacted. Availability is not affected.
Mitigation Recommendations
This vulnerability is fixed in Kestra version 1.3.24. Users should upgrade to version 1.3.24 or later to remediate this issue. No official remediation level or patch link is provided, but the fix is included in the stated version. Until upgraded, restrict database read access to trusted users only to reduce risk.
