Security readout for executives and security teams
CVE-2010-4890 is a cross-site scripting issue in the TYPO3 Yet Another Calendar extension, also called ke_yac, before version 1.1.2. A remote attacker could inject script or HTML through unspecified inputs. The source bundle does not provide CVSS, affected CPEs, or active exploitation evidence. Exposure is likely limited to TYPO3 sites that installed the ke_yac extension before 1.1.2. The bundle does not identify core TYPO3 as affected, nor does it provide package identifiers, CPEs, or deployment prevalence. Handle as a targeted legacy web-risk cleanup, not a confirmed emergency. Prioritize if the organization still operates old TYPO3 sites or public-facing ke_yac calendar functionality, because XSS can affect users and site trust. Mitigation focus: Identify whether any TYPO3 site uses the ke_yac extension.; Upgrade ke_yac to version 1.1.2 or vendor-supported later release.; Review the TYPO3 security bulletin for vendor-specific guidance..
