prefs.php in phpBB 1.4.0 and earlier allows remote authenticated users to execute arbitrary PHP code via an invalid language value, which prevents the variables (1) $l_statsblock in prefs.php or (2) $l_privnotify in auth.php from being properly initialized, which can be modified by the user and later used in an eval statement.

Exploit prediction (EPSS)

7.70% probability of exploitation in the next 30 days, higher than 95% of all scored CVEs.
