AI-suggested
Upgrade @novu/application-generic to version 3.17.0 or later, where the SSRF guard validateUrlSsrf has been updated to block the 100.64.0.0/10 shared address space. This patch addresses the gap in the deny-list and prevents SSRF requests to these addresses. No additional action is required if already using version 3.17.0 or later.
Description
The @novu/application-generic package contains a server-side request forgery (SSRF) protection function called validateUrlSsrf that fails to block the 100.64.0.0/10 shared address space (CGNAT). This omission allows server-side requests to potentially sensitive internal or cloud provider metadata services, such as Alibaba Cloud's metadata endpoint at 100.100.100.200. The vulnerability affects versions prior to 3.17.0 and has been fixed in version 3.17.0.
