Analysis

Technical impact

Affected Systems

Risk and Exploitability

The CVSS score of 7.1 indicates high severity. The EPSS score is below 1%, suggesting a low likelihood of widespread exploitation at the time of analysis, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is client‑side, requiring a victim to visit a crafted URL or interact with a page that reflects unsanitized input in the Contexto plugin. Exploitation would cause the execution of arbitrary script code within the victim’s browser session.
