CVE-2026-35209

defu is software that allows uers to assign default properties recursively. Prior to version 6.1.5, applications that pass unsanitized user input e.g. parsed JSON request bodies, database records, or config files from untrusted sources as the first argument to defu are vulnerable to prototype...

CVE-2026-35209

CVE-2026-35209 affects defu, a recursive defaults merger. Before v6.1.5, the vulnerable code path uses Object.assign({}, defaults) in _defu, which can trigger the proto setter and pollute the Object prototype, allowing attacker-controlled values to appear in the final result. The vulnerability ar...

defu security vulnerabilities

Defu is a lightweight tool library developed by UnJS for recursively merging default values. Versions of Defu prior to 6.1.5 contained security vulnerabilities; these vulnerabilities stemmed from the practice of passing uncleaned user input into the Defu functions, which could lead to prototype...
