CVE-2026-50288: Asymmetric-Effort Specifyjs

High severity, CVSS 8.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

• Asymmetric-Effort Specifyjs: before 0.2.136 (fixed in 0.2.136)
