Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

libraries/auth/swekey/swekey.auth.lib.php in the Swekey authentication feature in phpMyAdmin 3.x before 3.3.10.2 and 3.4.x before 3.4.3.1 assigns values to arbitrary parameters referenced in the query string, which allows remote attackers to modify the SESSION superglobal array via a crafted request, related to a "remote variable manipulation vulnerability."
