Vault Vulnerable to Denial of Service Due to Rate Limit Regression

Vault and Vault Enterprise (“Vault”) are vulnerable to an unauthenticated denial of service when processing JSON payloads.

This vulnerability, CVE-2025-12044, is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.16.27, 1.19.11, 1.20.5, and 1.21.0.
