It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked. Source: https://cve.now/CVE-2026-124698 ### What does this mean? The Chart default tooltip can display string values an attacker controls, so script can run in the user's browser when the user hovers over the affected point. That could expose or alter data in the browser context.
