Improper resource allocation In devalue

Description

Svelte devalue: DoS via malformed input

Impact

devalue.parse prior to version 5.9.2 fails to reject out-of-bounds indices. Specially-crafted payloads can exploit this to cause devalue to alternate between different array representations, resulting in work that is quadratic with payload size.

Applications are potentially affected if they call devalue.parse with untrusted data.

Patches

The bug is fixed in devalue@5.9.2.

Mitigation

Update Impact

Minimal update. May introduce new vulnerabilities or breaking changes.
