CVE-2026-66738

NVD: SPIP before 4.4.18 contains a code injection vulnerability in SQLite-backed installations. NVD: The navigation menu endpoint improperly handles array-typed user input, which bypasses input sanitization and allows the value to break out of an internal quoted string context when evaluated as PHP. NVD: An authenticated attacker with at minimum editor (redacteur) privileges can submit a single crafted GET request to /ecrire/?exec=navigation to execute arbitrary OS commands in the web server process.
