CVE-2026-8430

SPIP versions prior to 4.4.14 contain a remote code execution vulnerability in the public space that is limited to certain nginx configurations, allowing attackers to execute arbitrary code in the context of the web server. Attackers can exploit this vulnerability through specific nginx configuration scenarios to achieve code execution, and this issue is not mitigated by the SPIP security screen.
