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 the Kestra open-source orchestration platform prior to version 1.3.24. The BasicAuth authentication component uses SHA-512 hashing for passwords, which is fast and allows attackers with read access to the PostgreSQL database to recover administrator passwords offline. In Kubernetes environments, this can escalate privileges by exposing cluster ServiceAccount Tokens and Secrets. The vulnerability is addressed in Kestra 1.3.24.
Potential Impact
An attacker who can read the PostgreSQL database can exploit the fast SHA-512 password hashing to recover administrator credentials offline. In Kubernetes deployments, this leads to exposure of cluster ServiceAccount Tokens and Secrets, resulting in vertical privilege escalation and potential full cluster compromise.
Mitigation Recommendations
Upgrade Kestra to version 1.3.24 or later, where the vulnerability is fixed. No other mitigation guidance is provided. Patch status is confirmed by the vendor advisory stating the fix is in 1.3.24.
