Start with CVECheckService.java at retrieveVulnerabilityData (line 312), then trace fetchCves, getCveUpgradeIssues, and batchGetCVEIssues from the reported stack trace. Reproduce the GitHub Security Advisory API connection timeout on the listed IntelliJ, Windows 11, and JDK versions. The issue does not specify the expected timeout behavior or a test file, so clarify the desired handling before defining done.
