Vulnerability from fkie_nvd - Published: 2025-10-23 20:15 - Updated: 2026-10-18 21:10
Severity
Summary
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.
