EGroupware (PHP-based web groupware) contains an authenticated SQL injection in core components prior to 23.1.20260113 and 26.0.20260113 within Nextmatch widget filter processing. Due to PHP JSON decoding type juggling (numeric strings becoming integers), attacker-supplied filter data can bypass an is_int() validation check and be incorporated into the generated SQL WHERE clause, allowing injection of arbitrary SQL into database queries.
