Start with CVECheckService.java, especially retrieveVulnerabilityData at line 312 and its callers fetchCves, getCveUpgradeIssues, and batchGetCVEIssues. Reproduce the GitHub Security Advisory API failure on the reported IntelliJ, Windows 11, JDK, and plugin versions; done means the cause and expected handling of the aborted connection are established.
