Start with CVECheckService.retrieveVulnerabilityData at line 312, then trace fetchCves, getCveUpgradeIssues, and batchGetCVEIssues in the stack trace. Reproduce or investigate the GitHub Security Advisory API connection timeout on the reported IntelliJ, Windows, and JDK versions. The issue does not specify expected timeout behavior, so confirm acceptance criteria before deciding what done means.
