Last modified

CVE-2018-12115 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.. EPSS estimates a 8.09% chance of exploitation in the next 30 days.
