CVE-2018-16472

Status: ModifiedHigh (7.5)—

A prototype pollution attack in cached-path-relative versions <=1.0.1 allows an attacker to inject properties on Object.prototype which are then inherited by all the JS objects through the prototype chain causing a DoS attack.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
