🧬 Weakness Anatomy — CWE-79, the underlying flaw class

This vulnerability is classified as CWE-79: Cross-Site Scripting (XSS) in the primary record. The mechanics below are characteristic of this weakness class (per the MITRE CWE corpus), not a claim about a specific exploit observed against your environment.

How it's exploited	Attacker injects script into pages rendered to other users, running in their browser session to steal cookies/tokens or perform actions as the victim.
Detect & prevent	Context-aware output encoding; Content-Security-Policy; sanitize rich input. Detect via WAF signatures for script payloads and anomalous parameter content.

⚠️ Business Impact Analysis

⚠️ Remote code execution — full server takeover without authentication possible
