A vulnerability, which was classified as problematic, was found in ChestnutCMS up to 1.5.3. Affected is the function readFile of the file /dev-api/cms/file/read. The manipulation of the argument filePath leads to path traversal. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

In Docker before versions 9.03.15, 20.10.3 there is a vulnerability involving the --userns-remap option in which access to remapped root allows privilege escalation to real root. When using "--userns-remap", if the root user in the remapped namespace has access to the host filesystem they can modify files under "/var/lib/docker/<remapping>" that cause writing files with extended privileges. Versions 20.10.3 and 19.03.15 contain patches that prevent privilege escalation from remapped user.
