CVSS 3.1
5.3 mediumCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:NCVE-2022-25839
Medium (5.3) in url-js project url-js. EPSS 0.8% chance of exploitation in the next 30 days. Fixed in url-js 2.1.0.
The package url-js before 2.1.0 are vulnerable to Improper Input Validation due to improper parsing, which makes it is possible for the hostname to be spoofed. http://\\\\\\\\localhost and http://localhost are the same URL. However, the hostname is not parsed as localhost, and the backslash is reflected as it is.
