Alchemy CMS versions 2.x through 6.0.0 suffers from an arbitrary file upload vulnerability.

An issue was discovered in CMS Made Simple 2.2.8. It is possible to achieve unauthenticated path traversal in the CGExtensions module (in the file action.setdefaulttemplate.php) with the m1_filename parameter; and through the action.showmessage.php file, it is possible to read arbitrary file content (by using that path traversal with m1_prefname set to cg_errormsg and m1_resettodefault=1).

squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link and then contents under the same filename in a filesystem can cause unsquashfs to first create the symbolic link pointing outside the expected directory, and then the subsequent write operation will cause the unsquashfs process to write through the symbolic link elsewhere in the filesystem.

Tar.php in Archive_Tar through 1.4.11 allows write operations with Directory Traversal due to inadequate checking of symbolic links, a related issue to CVE-2020-28948.
