Lifecycle Timeline
2DescriptionCVE.org
Kestra is an open-source, event-driven orchestration platform. Prior to 2.0.0-rc6, Kestra's cli/src/main/resources/application.yml serves Micronaut management endpoints on port 8081 without authentication even when Basic Auth protects /api/v1/** on port 8080, allowing unauthenticated GET /env requests to disclose resolved configuration and POST /loggers/{name} requests to change runtime log levels. This issue is fixed in 2.0.0-rc6.
AnalysisAI
Unauthenticated access to Micronaut management endpoints in Kestra prior to 2.0.0-rc6 allows any network-reachable attacker to read fully resolved configuration via GET /env or manipulate runtime log levels via POST /loggers/{name}, bypassing the Basic Auth controls that protect only the primary API on port 8080. The management port (8081) is configured in application.yml with no equivalent authentication gate, making this a structural authentication bypass rather than a misconfiguration edge case. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that port 8081 (Micronaut management port) be reachable from the attacker's network - this is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N scores 6.5 (Medium), but the vendor-assigned C:L for confidentiality likely understates real-world impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access to port 8081 of a Kestra deployment - whether through internet exposure, VPN access, or lateral movement within a cloud environment - sends an unauthenticated HTTP GET to /env and receives the fully resolved Kestra configuration in response, potentially including database passwords, object storage credentials, or third-party API keys used by orchestrated workflows. With those credentials, the attacker pivots to connected data stores or cloud services. … |
| Remediation | Upgrade Kestra to 2.0.0-rc6 or later, which resolves this issue per the vendor advisory at https://github.com/kestra-io/kestra/security/advisories/GHSA-hpj9-grjp-7vc7. … Detailed patch versions, workarounds, and compensating controls in full report. |
