Blind SSRF in SPIP Syndicated Sites Allows Arbitrary Server Requests

Publication date: 2026-02-19

Last updated on: 2026-02-24

Assigner: VulnCheck

Description
SPIP before 4.4.9 allows Blind Server-Side Request Forgery (SSRF) via syndicated sites in the private area. When editing a syndicated site, the application does not verify that the syndication URL is a valid remote URL, allowing an authenticated attacker to make the server issue requests to arbitrary internal or external destinations. This vulnerability is not mitigated by the SPIP security screen.

Executive Summary

This vulnerability exists in SPIP versions before 4.4.9 and is a Blind Server-Side Request Forgery (SSRF) issue. It occurs in the private area when editing a syndicated site. The application does not verify whether the syndication URL is a valid remote URL, which allows an authenticated attacker to make the server send requests to arbitrary internal or external destinations. The SPIP security screen does not mitigate this vulnerability.

Impact Analysis

An attacker who is authenticated can exploit this vulnerability to make the server perform requests to arbitrary internal or external systems. This can lead to unauthorized access to internal resources, potential data exposure, or interaction with internal services that are not normally accessible externally. Since the vulnerability is a Blind SSRF, the attacker may not see the response directly but can still cause the server to interact with unintended targets.
