The flaw allows attackers to inject and execute arbitrary JavaScript within a victim’s browser. No further effects are described in the CVE summary. Based on the description, the likely attack vector involves a specially crafted GET request that returns the injected payload in the rendered page.
Affected Systems

Risk and Exploitability
The CVSS score of 7.1 indicates high severity. EPSS is below 1%, suggesting a low probability of widespread exploitation, though it is not listed in KEV.
