The Freemius SDK, as used by hundreds of WordPress plugin and theme developers, was vulnerable to Cross-Site Request Forgery and Information disclosure due to missing capability checks and nonce protection on the _get_debug_log, _get_db_option, and the _set_db_option functions in versions up to, and including 2.4.2. Any WordPress plugin or theme running a version of Freemius less than 2.4.3 is vulnerable.

A vulnerability classified as critical was found in SourceCodester Simple File Manager 1.0. This vulnerability affects unknown code. The manipulation of the argument photo leads to unrestricted upload. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. VDB-257770 is the identifier assigned to this vulnerability.

A path traversal vulnerability exists in simple-file-manager before 2017-04-26, affecting index.php (the sole "Simple PHP File Manager" component).

Multiple directory traversal vulnerabilities in fm.php in Simple File Manager (SFM) 0.24a allow remote attackers to use ".." sequences to (1) read arbitrary files via the filename parameter in a download action, (2) delete arbitrary files via the delete parameter, and (3) modify arbitrary files via the edit parameter, which can be leveraged to execute arbitrary code.

Cross-site scripting (XSS) vulnerability in fm.php in ONEdotOH Simple File Manager (SFM) 0.24a and earlier allows remote attackers to inject arbitrary web script or HTML via the msg parameter.

Cross-site scripting (XSS) vulnerability in ONEdotOH Simple File Manager (SFM) before 0.21 allows remote attackers to inject arbitrary web script or HTML via (1) file names and (2) directory names.
