Packages node-lodash - A modern JavaScript utility library delivering modularity, performance, & extras Details It was discovered that Lodash was vulnerable to a prototype pollution issue in the zipObjectDeep function. An attacker could possibly use this issue to modify application behavior. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-8203) Liyuan Chen discovered that Lodash was vulnerable to a regular expression denial of service issue in the toNumber, trim, and trimEnd functions. An attacker could possibly use this issue to consume excessive system resources, resulting in a denial of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-28500) Marc Hassan discovered that Lodash did not properly sanitize input to the template function. An attacker could possibly use this issue to inject and execute arbitrary commands.
