SPIP before 4.4.29 contains a SQL injection vulnerability that allows authenticated attackers with back-office access to inject arbitrary SQL by submitting a differing where parameter value in the POST body versus the GET query string on the /ecrire/?exec=articles endpoint, bypassing spip_sanitize_from_request() sanitization. Attackers can exploit this request parameter mismatch to extract database contents, including protected articles and bcrypt password hashes of users.
