Prototype Pollution

Overview Affected versions of this package are vulnerable to Prototype Pollution via schema option path handling. An attacker can perform prototype pollution by supplying a crafted protobuf schema or JSON descriptor whose option paths traverse inherited properties, allowing writes to global...

CVE-2026-8161 multiparty vulnerable to Denial of Service via Prototype Pollution leading to Uncaught Exception

[email protected] and lower versions are vulnerable to denial of service via uncaught exception. By sending a multipart/form-data request with a field name that collides with an inherited Object.prototype property such as proto, constructor, or toString, the parser invokes .push on the inherited...

CVE-2026-8161

This CVE affects [email protected] and earlier, where the parser stores fields/files on plain objects and can collide with inherited Object.prototype properties (e.g., proto , constructor, toString). The root cause is prototype pollution leading to a TypeError when .push() is invoked on a non-arra...

Prototype Pollution

Overview @rvf/set-get is an Internal utilities and types for working with deeply nested data. This is primarily used internally by RVF and it's various packages. It isn't recommended for use by most people. Affected versions of this package are vulnerable to Prototype Pollution via the setPath...

GHSA-C567-44RC-M5HQ @rvf/set-get has a prototype pollution issue that's reachable via @rvf/core preprocessFormData (HTTP form data)

Summary setPath in @rvf/set-get used by @rvf/core to flatten incoming form data into a nested object does not block the keys proto, constructor, or prototype when walking a path. Because field names in submitted form data are passed directly to setPath via preprocessFormData and through...
