What it is
JavaScript dependency risk refers to vulnerabilities introduced through third-party scripts, libraries, or frameworks loaded by a website, such as analytics tools, tag managers, chat widgets, or CDN-hosted libraries.
Why it matters
If a third-party JavaScript dependency is compromised, outdated, or maliciously altered, attackers can inject code directly into your website. This can lead to session hijacking, data theft, malware distribution, or compliance violations without any change to your own application code.
How to reduce risk
Audit all third-party scripts regularly, remove unused dependencies, pin exact library versions, and apply Subresource Integrity (SRI) where possible. Continuous external monitoring helps detect risky or newly introduced dependencies.
