libxl provides Node bindings for the libxl library for reading and writing excel (XLS and XLSX) spreadsheets. libxl downloads zipped resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested zip file with an attacker controlled zip file if the attacker is on the network or positioned in between the user and the remote server.

Exploit prediction (EPSS)

1.73% probability of exploitation in the next 30 days, higher than 78% of all scored CVEs.
