Summary

Prototype pollution vulnerability in the dot-access library up to version 1.0.0. An attacker controlling the path (e.g., via user-supplied field names) can use __proto__ segments to inject properties into all objects.

Risk Assessment

This can alter authorization flags, default options, or crash the process, affecting application security and stability.

Recommendation

Update the dot-access library to the latest version if a fix is available. Avoid passing untrusted paths to the set() function.

Other vulnerabilities in dot-access

CVE-2026-107700Critical
The dot-access library versions 0.0.3 through 1.0.0 contain a code injection vulnerability. The path supplied to get() is concatenated into a new Function body in index.js, allowing attackers to reach constructor.constructor to load child_process and run operating system commands in the Node.js process.

Original NVD description (English source)

dot-access through 1.0.0 contains a prototype pollution vulnerability that allows attackers to modify Object.prototype by supplying a crafted dotted path to set(). Attackers controlling the path, such as through user-supplied field names, can use __proto__ segments to inject properties into all objects, altering authorization flags and option defaults or crashing the process.
