CVSS 3.1
9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2015-8857
Critical (9.8) in uglifyjs project uglifyjs. EPSS 3.6% chance of exploitation in the next 30 days. Fixed in uglify-js 2.4.24.
The uglify-js package before 2.4.24 for Node.js does not properly account for non-boolean values when rewriting boolean expressions, which might allow attackers to bypass security mechanisms or possibly have unspecified other impact by leveraging improperly rewritten Javascript.
