Fix not verifiedThere is an HTML injection issue in Esri ArcGIS Web AppBuilder developer edition versions prior to 2.30 that allows a remote, unauthenticated attacker to potentially entice a user to click a link that causes arbitrary HTML to render in a victim's browser. There is no evidence of JavaScript execution, which limits the impact. At the time of submission, ArcGIS Web App Builder developer edition is retired and unsupported. ArcGIS Web App Builder 2.30 is not susceptible to this vulnerability.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
