CVE-2026-52743: GoCD before 26.1.0 is vulnerable to authorization bypass via job status API
Noroxi assessment
Priority: Monitor (action score 17/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.40% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: gocd gocd 26.1.0.
Low priority for now. Upgrade to gocd gocd 26.1.0 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
GoCD is a continuous deliver server. Prior to 26.1.0, the internal GoCD UI /jobStatus.json API does not validate that a requested server-assigned job ID belongs to the pipeline and stage named in the request. An authenticated user can guess job IDs and retrieve status for jobs in pipelines the user cannot otherwise view, including job names, state, progress timestamps, assigned agent IP addresses and UUIDs, and associated stages and pipelines. The response does not expose console output, artifacts, commands, variables, or configuration. This issue is fixed in version 26.1.0.
