EPSS

• CVE-2018-19413: 1.15% estimated exploitation activity in the next 30 days; percentile 66.94 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

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.

# Patch Next advisory brief: CVE-2018-19413

Advisory: Exposure of Sensitive Information to an Unauthorized Actor in SonarSource SonarQube API
IDs: CVE-2018-19413, GHSA-m643-2pfv-xwm8
Record: https://patchnext.com/advisories/cve-2018-19413 (revision 1, source checked 26 Oct 2026, 16:26 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.sonarsource.sonarqube:sonar-plugin-api 7.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.sonarsource.sonarqube:sonar-plugin-api: affected < 7.5; fixed in 7.5

## Suggested inspection (read-only)
- Maven org.sonarsource.sonarqube:sonar-plugin-api: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.sonarsource.sonarqube:sonar-plugin-api.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-m643-2pfv-xwm8 (GitHub-reviewed advisory GHSA-m643-2pfv-xwm8 lists affected ranges: Maven org.sonarsource.sonarqube:sonar-plugin-api >=0 <7.5)
