CVE-2026-8726: SQL Injection in extension "News system" (news)
The extension fails to properly sanitize user input before using it in a database query. As a result, an unauthenticated attacker can inject arbitrary SQL through a URL parameter on pages using the "Date Menu of news articles" plugin. Exploitation requires the "Date Menu of news articles" plugin to be in use and the TypoScript/Plugin setting disableOverrideDemand not to be enabled.
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.

CWE-89: Database access and collection lookup
Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

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.
