Summary
Vault Vulnerable to Denial of Service Due to Rate Limit Regression
Details

Vault and Vault Enterprise (“Vault”) are vulnerable to an unauthenticated denial of service when processing JSON payloads. This occurs due to a regression from a previous fix for [+HCSEC-2025-24+|https://discuss.hashicorp.com/t/hcsec-2025-24-vault-denial-of-service-though-complex-json-payloads/76393]  which allowed for processing JSON payloads before applying rate limits. 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.
