CVE-2026-72708
SPIP < 4.4.18 Unauthenticated Blind SQL Injection via sitemap.xml.html
CVE-2026-72708 is a high vulnerability (CVSS 8.7) in Spip, published September 11, 2026. Public exploit code exists. EPSS puts the chance of exploitation in the next 30 days at 0.52%, the 44th percentile. Fixed in spip 4.4.19+dfsg-0+deb13u1.
SPIP before 4.4.18 contains an unauthenticated blind SQL injection vulnerability in the SQL escaping layer that allows unauthenticated attackers to inject arbitrary SQL by supplying a crafted annee parameter value matching a word character followed by an open parenthesis, which bypasses escaping for date-type columns across MySQL, SQLite, and PostgreSQL backends. Attackers can exploit the always-present sitemap.xml.html template's annee criterion to embed unescaped time-based or boolean payloads into database queries, enabling extraction of arbitrary database content including the alea_ephemere secret used to sign SPIP action nonces.

SPIP before 4.4.18 contains an unauthenticated blind SQL injection vulnerability in the public sitemap endpoint where the MySQL escaper spip_mysql_cite() in ecrire/req/mysql.php returns values unescaped when the target column is a date type and the supplied value matches the pattern of a word character followed by an open parenthesis. Attackers can supply a crafted value such as a time-based payload through the annee parameter in squelettes-dist/sitemap.xml.html to embed arbitrary SQL directly into the generated query, enabling time-based and boolean-based blind SQL injection that can expose arbitrary database content including the alea_ephemere secret used to sign action nonces.
