Vulnerability identifier: #VU58205
Vulnerability risk: Medium
Exploitation vector: Network
Vendor: npm Inc.
The vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to a logic issue when file paths contained repeated path roots such as
would only strip a single path root from such paths. When given an
absolute file path with repeating path roots, the resulting path (e.g.
///home/user/.bashrc) would still resolve to an absolute path, thus allowing arbitrary file creation and overwrite.
