CVE-2026-50288: CWE-918: Server-Side Request Forgery (SSRF) in asymmetric-effort specifyjs
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.
AI Analysis
Technical Summary
SpecifyJS is a TypeScript UI framework. Before version 0.2.136, when the new URL() constructor threw a parse error, the assertSecureUrl function caught the error but returned silently without throwing, effectively allowing insecure requests to proceed without HTTPS validation. This behavior constitutes a security vulnerability (CWE-918: Insecure Default Initialization) that could lead to insecure network communication. The issue is resolved in version 0.2.136 by modifying the catch block to throw an error, preventing silent bypass of HTTPS validation.
Potential Impact
Requests with malformed URLs could bypass HTTPS validation, potentially allowing insecure or unintended network requests. This could lead to data exposure or man-in-the-middle attacks if insecure HTTP requests are allowed where HTTPS is expected. The vulnerability does not require privileges or user interaction and is exploitable remotely.
Mitigation Recommendations
Upgrade SpecifyJS to version 0.2.136 or later, where the vulnerability is fixed by throwing an error on URL parse failure instead of silently allowing the request. No other mitigations are indicated.
