HIGHPre-NVD 8.78.7—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% 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).

SpecifyJS is a declarative TypeScript user interface framework. Prior to version 0.2.136, when new URL() throws a parse error, the assertSecureUrl function returned without throwing, silently allowing the request to proceed without HTTPS validation. Starting in version 0.2.136, the catch block now throws an error instead of silently returning.
