CVE-2018-5164

MEDIUM

Firefox < 60.0 - Cross-Site Scripting via Multipart Content CSP Bypass

Title source: llm
STIX 2.1

Description

Content Security Policy (CSP) is not applied correctly to all parts of multipart content sent with the "multipart/x-mixed-replace" MIME type. This could allow for script to run where CSP should block it, allowing for cross-site scripting (XSS) and other attacks. This vulnerability affects Firefox < 60.
