Dear @sgastevep
Thank you for letting us know about this.
Could you please share the security vulnerability details shown in the Jetpack notice, preferably a screenshot or the vulnerability name/CVE number? This will help us identify exactly which issue Jetpack is reporting and verify whether it is related to CTX Feed.
In the meantime, please make sure that CTX Feed is updated to the latest available version. After updating, please regenerate the feed and check whether Jetpack continues to report the same vulnerability.
Once you share the Jetpack vulnerability details, we can investigate this further and confirm whether any action is required from our side.
Best regards,
