CVE-2022-3708
The Web Stories plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including 1.24.0 due to insufficient validation of URLs supplied via the 'url' parameter found via the /v1/hotlink/proxy REST API Endpoint.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
