Technical details
The plugin fails to validate destination URLs or check user capabilities before fetching a user-supplied feed URL server-side. An attacker with contributor access (or higher) can craft a malicious feed URL pointing to internal resources, causing the server to make requests and return responses that reveal internal system information. The vulnerability is an SSRF (CWE-918) requiring authentication at the contributor level or above.
