CVE-2019-19850: An issue was discovered in TYPO3 before 8.7.30, 9.x before 9.5.12, and 10.x before 10.2.2.

An issue was discovered in TYPO3 before 8.7.30, 9.x before 9.5.12, and 10.x before 10.2.2. Because escaping of user-submitted content is mishandled, the class QueryGenerator is vulnerable to SQL injection. Exploitation requires having the system extension ext:lowlevel installed, and a valid backend user who has administrator privileges.

Security readout for executives and security teams

Plain-English summary

CVE-2019-19850 is a TYPO3 SQL injection flaw, but it is constrained. An attacker needs valid backend administrator access and the lowlevel system extension installed. Organizations on older TYPO3 8, 9, or 10 branches should still prioritize patching because successful exploitation could expose sensitive database data.

Executive priority

Treat as a moderate-priority remediation item. It is not described as remotely exploitable without admin access, but unpatched TYPO3 admin surfaces can expose high-value database data if administrator credentials are abused.

Technical view

TYPO3 QueryGenerator mishandles escaping of user-submitted content, creating SQL injection risk. Affected versions are before 8.7.30, 9.5.12, and 10.2.2. Exploitation requires ext:lowlevel and an authenticated backend user with administrator privileges. CVSS v3.0 is 5.5 with high confidentiality impact.

Likely exposure

Exposure is mainly TYPO3 administrative backends running vulnerable versions with ext:lowlevel installed. Public-facing anonymous users are not described as able to exploit this issue in the supplied sources.

Exploitation context

The source bundle does not indicate CISA KEV listing or active exploitation. The required backend administrator privileges materially reduce broad internet exploitation risk, but compromised admin accounts could turn this into database access risk.

Researcher notes

Focus validation on vulnerable TYPO3 branches, ext:lowlevel presence, and backend admin privilege paths. The supplied evidence identifies the vulnerable class and prerequisites, but does not provide indicators of compromise or public exploit status.

Mitigation direction

  • Upgrade TYPO3 to 8.7.30, 9.5.12, 10.2.2, or later supported releases.
  • Check the TYPO3 advisory for branch-specific upgrade guidance.
  • Remove or disable ext:lowlevel where it is not operationally required.
  • Review and restrict TYPO3 backend administrator accounts.
  • Prioritize supported TYPO3 branches over legacy unsupported deployments.

Validation and detection

  • Inventory TYPO3 core versions across all environments.
  • Check whether ext:lowlevel is installed and enabled.
  • Verify backend administrator accounts are expected and individually assigned.
  • Confirm upgraded systems report fixed TYPO3 versions.
  • Review vendor advisory and linked TYPO3 review records for patch context.
