CVE-2026-62682: Orval: RCE via servers[].url -> unescaped request-URL template literal (with getBaseUrlFromSpecification)
When Orval is configured with output.baseUrl.getBaseUrlFromSpecification: true, it bakes the spec’s servers[0].url into the generated request URL as a template literal without escaping the backtick. A server URL containing a backtick closes the template literal and injects a concatenation expression evaluated when the generated URL/request function is called, executing attacker-controlled code. Verified on Orval 8.19.0 (fetch client); survives default OpenAPI validation.
