Security readout for executives and security teams
Plain-English summary
This is a SQL injection flaw in the TYPO3 News system extension. An unauthenticated visitor may be able to manipulate a database query through a URL parameter, but only on sites using the Date Menu of news articles plugin with a specific override-protection setting left disabled.
Executive priority
Treat this as a high-priority website exposure review, especially for public TYPO3 sites. Business urgency depends on whether the vulnerable plugin is present and configured in the risky mode; confirm that first, then patch or disable the risky feature path.
Technical view
CVE-2026-8726 is CWE-89 in TYPO3 extension georgringer/news. The supplied record says unsanitized user input reaches a database query via a URL parameter on Date Menu plugin pages. Exploitability depends on that plugin being used and disableOverrideDemand not being enabled. CVSS v4.0 score is 8.2.
Likely exposure
Exposure is limited to TYPO3 sites with the News system extension and pages using the Date Menu of news articles plugin. The CVE bundle lists affected version lines including 11.0.0, 12.0.0, 13.0.0, 14.0.0, and 0, but does not provide fixed versions.
Exploitation context
The CVE is not marked KEV in the supplied bundle, and no cited source in the prompt states active exploitation. The issue is still serious because it is unauthenticated, network-reachable, low complexity, and can expose database confidentiality where the vulnerable plugin configuration exists.
Researcher notes
Evidence is configuration-dependent. The supplied data confirms SQL injection, unauthenticated reachability, CVSS 8.2, and the required Date Menu plus disableOverrideDemand condition. It does not include exploit proof, active exploitation, affected subranges, or fixed version details.
Mitigation direction
- Review the TYPO3 vendor advisory for fixed releases and upgrade guidance.
- Enable disableOverrideDemand for affected News Date Menu plugin usage where compatible.
- Disable or remove the Date Menu of news articles plugin if not required.
- Prioritize remediation on internet-facing TYPO3 sites using georgringer/news.
- Monitor vendor guidance for exact fixed versions and configuration notes.
Validation and detection
- Inventory TYPO3 installations using the georgringer/news extension.
- Identify public pages using the Date Menu of news articles plugin.
- Verify whether disableOverrideDemand is enabled for those plugin instances.
- Compare installed extension versions against the TYPO3 advisory.
- Review web logs for unusual URL-parameter activity on affected pages.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
