CVE-2026-107701
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().
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
