CVE-2021-23682

Status: ModifiedCritical (9.8)—

This affects the package litespeed.js before 0.3.12; the package appwrite/server-ce from 0.12.0 and before 0.12.2, before 0.11.1. When parsing the query string in the getJsonFromUrl function, the key that is set in the result object is not properly sanitized leading to a Prototype Pollution vulnerability.

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).
