Description
A vulnerability in the API of SonarSource SonarQube before 7.5 could allow an authenticated user to discover sensitive information such as valid user-account logins in the web application. The vulnerability occurs because of improperly configured access controls that cause the API to return the externalIdentity field to non-administrator users. The attacker could use this information in subsequent attacks against the system.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.sonarsource.sonarqube:sonar-plugin-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.sonarsource.sonarqube:sonar-plugin-api to 7.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-19413 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
