Cross-site scripting (XSS) vulnerability in HumHub 0.20.0-beta.1 through 0.20.1 and 1.0.0-beta before 1.0.0-beta.3 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.
SQL injection vulnerability in the actionIndex function in protected/modules_core/notification/controllers/ListController.php in HumHub 0.10.0-rc.1 and earlier allows remote authenticated users to execute arbitrary SQL commands via the from parameter to index.php. NOTE: this can be leveraged for cross-site scripting (XSS) attacks via a request that causes an error.
