## [Zebra 4.3.0](https://github.com/ZcashFoundation/zebra/releases/tag/v4.3) - 2026-03-12

This release fixes **two important security issues**:

- [CVE-2026-34202: Remote Denial of Service via Crafted V5 Transactions](https://github.com/ZcashFoundation/zebra/security/advisories/GHSA-qp6f-w4r3-h8wg)

The impact of the issue for crate users will depend on the particular usage;
if you use zebra-chain to parse untrusted transactions, a particularly crafted
transaction will raise a panic which will crash your application; you should
update.
