Security readout for executives and security teams
CVE-2010-4891 affects TYPO3 sites using the Yet Another Calendar, ke_yac, extension before version 1.1.2. It is a SQL injection issue, meaning an attacker may be able to manipulate database queries remotely. Business impact depends on whether the old extension is still installed and reachable. Exposure is likely limited to legacy TYPO3 deployments that installed ke_yac before 1.1.2. Sites without this extension are not indicated as affected by the provided sources. Public-facing TYPO3 instances should be checked first. Treat this as a legacy exposure check. It is not shown as actively exploited in the bundle, but remote SQL injection can threaten database confidentiality and integrity if an affected TYPO3 site remains online. Mitigation focus: Upgrade ke_yac to version 1.1.2 or a later vendor-supported release.; Check TYPO3 security bulletin TYPO3-SA-2010-018 for vendor guidance.; Remove the extension if it is unused or unsupported..
