MEDIUMPre-NVD 6.16.1—
EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 91% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. In versions 8.0.0-next.0 through 8.2.0 and 9.0.0 through 9.0.2, the error.message is interpolated into the default HTML exception response without escaping, allowing a crafted missing-route URL to execute attacker-controlled JavaScript when a victim opens it and no custom status page or JSON response handles the error. When debug mode is disabled and no custom status page handles the error, the default HTML renderer interpolates error.message directly into an HTML response. This issue is fixed in versions 8.2.1 and 9.1.0.
