What is CVE-2025-68130?

A prototype pollution vulnerability was discovered in the formDataToObject function of tRPC's @trpc/server, affecting versions up to 10.44.0 and 11.7.0. This issue arises specifically when using the experimental features experimental_caller or experimental_nextAppDirCaller. By exploiting this vulnerability, an attacker can manipulate Object.prototype through specially crafted FormData field names, which may result in critical security issues such as authorization bypass or potential denial of service scenarios. To mitigate this risk, users are advised to upgrade to versions 10.45.3 or 11.8.0, where the vulnerability has been addressed. For more details, refer to the official advisory.
