What is CVE-2026-27472?

SPIP prior to version 4.4.9 is susceptible to a blind server-side request forgery (SSRF) vulnerability due to improper validation of syndication URLs in the private area. This flaw enables authenticated attackers to send requests from the server to unauthorized internal or external destinations when managing syndicated sites. The existing security measures within SPIP do not effectively mitigate this issue, posing a significant risk to the integrity and confidentiality of server resources.
