It's an authorization bypass which works since version 1.9.5 from 2014 (current is 126.96.36.199) because PLA uses '==' instead of '===' for the password comparison in 'attemptGrant' of the 'Authorization' class. If the password is set to one which correspondends to a number in scientific notation, one could easier bruteforce the password or bypass it completely, e.g.: php > var_dump('200' == '2e2'); bool(true) php > var_dump('0' == '0e2'); bool(true) php > var_dump('0' == '0e2342'); bool(true) I opened an issue at GitHub for this and have written about it (section 2 is the interesting one for this issue). Best, Karsten  https://github.com/phpLiteAdmin/pla/issues/11  http://k3research.outerhaven.de/posts/small-mistakes-lead-to-big-problems.html
