Security Vulnerability - Arbitrary File Deletion via HTTP GET /tcdrop/deleteCachedFile

Heyyy! The endpoint "/tcdrop/deleteCachedFile" is vulnerable to arbitrary file deletion attacks. There deletion relies on a user supplied input via the "file" parameter. There is no validation of the input and if a user supplies a payload like this `file=../../../../../../../../../../../tmp/abc4.txt`, it can technically delete any file given whatever access right it has.
