CVE-2025-57820
Svelte devalue vulnerable to prototype pollution
Summary
Svelte devalue vulnerable to prototype pollution
Original description
The description as published by the source.
Svelte devalue is a utility library. Prior to version 5.3.2, a string passed to devalue.parse could represent an object with a proto property and devalue.parse does not check that an index is numeric. This could result in assigning prototypes to objects and properties, leading to prototype pollution. This issue has been fixed in version 5.3.2
