Jenkins SmallTest Plugin 1.0.4 and earlier does not perform hostname validation when connecting to the configured View26 server that could be abused using a man-in-the-middle attack to intercept these connections.

Security readout for executives and security teams

Plain-English summary

Jenkins SmallTest Plugin 1.0.4 and earlier may trust the wrong server identity when connecting to its configured View26 server. An attacker positioned between Jenkins and that server could intercept or alter the connection. The business concern is exposure of CI/CD-related data and potential integrity impact where this plugin is still installed and used.

Executive priority

Treat as high priority for Jenkins environments that use SmallTest Plugin with View26. The risk is narrower than a broadly exposed remote code execution issue, but CI/CD systems are sensitive, and interception or tampering with trusted integrations can create downstream business impact.

Technical view

The issue is CWE-295: improper certificate hostname validation. The plugin does not validate the hostname for TLS connections to the configured View26 server. CVSS is 8.1 high, with network attack vector, high attack complexity, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure appears limited to Jenkins environments running SmallTest Plugin 1.0.4 or earlier with a configured View26 server connection. Organizations not using this plugin, or not connecting it to View26, are unlikely to be affected based on the provided sources.

Exploitation context

The provided sources describe a man-in-the-middle attack scenario but do not report active exploitation. The CVE is not listed as KEV in the source bundle. Exploitation likely requires attacker positioning on the network path between Jenkins and the configured View26 server.

Researcher notes

Evidence is concise and source-limited. The advisory-backed weakness is missing hostname validation during View26 server connections. No exploit details, fixed version, or active exploitation evidence are provided in the supplied bundle, so validation should focus on plugin presence, version, and whether the vulnerable connection path exists.

Mitigation direction

  • Inventory Jenkins instances for SmallTest Plugin 1.0.4 or earlier.
  • Check Jenkins advisory and plugin guidance for any current fix or replacement.
  • Disable or remove the plugin where it is not required.
  • Restrict Jenkins-to-View26 connectivity to trusted network paths.
  • Monitor Jenkins outbound connections for unexpected View26 destinations.

Validation and detection

  • Confirm whether SmallTest Plugin is installed on each Jenkins controller.
  • Record installed plugin version and compare against 1.0.4 or earlier.
  • Verify whether a View26 server is configured for the plugin.
  • Review network controls protecting Jenkins-to-View26 traffic.
  • Check vendor advisory updates before closing remediation.

Improper Certificate Validation

Improper Certificate Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
