1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-33766)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to perform server-side request forgery against internal network resources and cloud metadata services.

The vulnerability exists due to improper restriction of outbound requests in image download endpoints when following HTTP redirects after validating a user-supplied URL. A remote user can supply a crafted URL that redirects to an internal target to perform server-side request forgery against internal network resources and cloud metadata services.

Only the file_get_contents and wget fallback paths are affected; the curl path is not affected. Exploitation requires upload and edit permissions.
