CVE-2026-27472Network attack vector

Authenticated blind SSRF via unvalidated syndication URLs

Published Feb 19, 2026 · Updated Feb 19, 2026

Blind SSRF in SPIP 4.4.0 through 4.4.8 allows remote authenticated users to make the server request arbitrary URLs via syndicated sites. The private-area syndicated-site editor accepts a syndication URL without verifying that it identifies a permissible remote destination. Site-editing access is required, and the resulting server-side requests can reach internal or external services without returning response content directly.
