What is CVE-2025-71241?

The SPIP content management system versions prior to 4.3.6, 4.2.17, and 4.1.20 are susceptible to a Cross-Site Scripting (XSS) vulnerability. This issue arises in the private area of the application, specifically through an inadequately sanitized error message generated by the 'transmettre' API. Attackers can exploit this flaw by injecting malicious scripts, potentially compromising the integrity of the application. Mitigation is available through the implementation of the SPIP security screen.
