CVE-2026-8726: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in TYPO3 Extension "News system"
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.
AI Analysis
Technical Summary
The TYPO3 extension "News system" versions 11.0.0 through 14.0.0 contain an SQL injection vulnerability (CWE-89) due to failure to properly neutralize special elements in user-supplied input before incorporating it into database queries. This vulnerability specifically affects the "Date Menu of news articles" plugin when the disableOverrideDemand setting is not enabled, enabling unauthenticated attackers to inject arbitrary SQL commands via crafted URL parameters. The vulnerability has a CVSS 4.0 base score of 8.2, indicating high severity. No official patch or remediation level has been published by TYPO3 as of the data provided.
Potential Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary SQL commands on the backend database through the vulnerable plugin, potentially leading to unauthorized data access or manipulation. The impact is significant given the high CVSS score and the lack of required privileges or user interaction. However, exploitation depends on specific plugin usage and configuration settings.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling the "Date Menu of news articles" plugin or enabling the TypoScript/Plugin setting disableOverrideDemand to mitigate the risk. Monitor official TYPO3 channels for updates and apply patches promptly once available.
