In JetBrains TeamCity before 2026.1 improper permission checks exposed build configuration parameters
AnalysisAI
Information disclosure in JetBrains TeamCity prior to version 2026.1 allows authenticated low-privilege users to read sensitive build configuration parameters they should not have access to due to missing authorization checks. The flaw carries a CVSS 7.6 score driven by high confidentiality impact on a network-reachable CI/CD server, though no public exploit identified at time of analysis. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker must hold a valid authenticated TeamCity account with at least low-privilege access (PR:L in the CVSS vector), so the server must be reachable by the attacker and they must possess or obtain working credentials - for example a developer, contractor, build-agent service account, or any role created via SSO/LDAP that grants basic TeamCity login. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L describes a remote, low-complexity attack requiring only low privileges and no user interaction, which is realistic for a multi-tenant CI server where many developers, contractors, and service accounts hold basic project-viewer roles. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A contractor or compromised developer account with only a basic project-viewer role on one team's project authenticates to the TeamCity REST API and issues a parameter-enumeration request against a build configuration belonging to a different, higher-privileged project. Because the authorization check is missing, the server returns the parameter values - including deployment credentials and cloud API tokens - which the attacker then uses to pivot into production infrastructure outside TeamCity. … |
| Remediation | Vendor-released patch: TeamCity 2026.1 - upgrade on-premises servers to 2026.1 or later as the primary fix, following the JetBrains upgrade guidance referenced from https://www.jetbrains.com/privacy-security/issues-fixed/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Audit all credentials currently stored in TeamCity build configuration parameters and review access logs for signs of unauthorized disclosure. …
