Name of the Vulnerable Software and Affected Versions ishayoyo excel-mcp versions prior to 1.0.3

Description A path traversal issue exists within the read file/write file component in the src/index.ts file. A remote attacker can exploit this by manipulating the filePath or outputPath arguments. Path traversal is a technique used to access files and directories that are stored outside the web root folder by manipulating variables that reference files with dot-dot-slash (../) sequences.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. Restrict the use of the filePath and outputPath arguments in the read file/write file component to minimize the risk of exploitation.
