CVE-2026-81176
### 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 `[email protected]`.
