Numerous Plugins and Themes from the AccessPress Themes (aka Access Keys) vendor are backdoored due to their website being compromised. Only plugins and themes downloaded via the vendor website are affected, and those hosted on wordpress.org are not. However, all of them were updated or removed to avoid any confusion

In post-new.php in the Photocrati NextGEN Gallery plugin 2.1.10 for WordPress, unrestricted file upload is available via the name parameter, if a file extension is changed from .jpg to .php.

Unrestricted file upload vulnerability in frames/upload-images.php in the Complete Gallery Manager plugin before 3.3.4 rev40279 for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in wp-content/[year]/[month]/.

Cross-site scripting (XSS) vulnerability in index.php for GOOP Gallery 2.0, and possibly other versions before 2.0.3, allows remote attackers to inject arbitrary HTML or web script via the image parameter.

Directory traversal vulnerability in Gallery 2.0.3 and earlier, and 2.1 before RC-2a, allows remote attackers to include arbitrary PHP files via ".." (dot dot) sequences in the stepOrder parameter to (1) upgrade/index.php or (2) install/index.php.

Cross-site scripting (XSS) vulnerability in Gallery 2 up to 2.0.2 allows remote attackers to inject arbitrary web script or HTML via the X-Forwarded-For (X_FORWARDED_FOR) HTTP header, which is not properly handled when adding a comment to an album.

Directory traversal vulnerability in the session handling class (GallerySession.class) in Gallery 2 up to 2.0.2 allows remote attackers to access and delete files by specifying the session in a cookie, which is used in constructing file paths before the session value is sanitized.

Unspecified vulnerability in the zipcart module in Gallery 2.0 before 2.0.2 allows remote attackers to read arbitrary files via unknown vectors.

The installer for Gallery 2.0 before 2.0.2 stores the install log under the web document root with insufficient access control, which allows remote attackers to obtain sensitive information.
