SPIP < 4.4.18 Unauthenticated Blind SQL Injection via sitemap.xml.html

Published Sep 11, 2026 · Updated Oct 12, 2026 · Assigned by VulnCheck

Vendor: SPIP Product: SPIP Package: spip Package: spip Ecosystem: Debian Ecosystem: Ubuntu

Description

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.
