CVE-2026-84185— Jwcrypto: jwcrypto: general json jws kid binding bypass during jwkset verification

Quick assessment

Affected
Red Hat Red Hat Ansible Automation Platform 2
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 库中发现一个缺陷，该库用于实现 JavaScript 对象签名与加密（JOSE）标准。 缺陷描述： 该问题发生在库验证“通用 JSON 序列化 JWS（JSON Web Signature）”时。由于代码编写错误，库无法正确识别特定的密钥 ID（kid），而是可能接受由密钥集中任意有效密钥生成的签名。 潜在影响： 如果应用程序依赖密钥 ID（kid）来识别特定的租户或用户，拥有有效密钥的攻击者可以利用此缺陷绕过授权检查。

Vulnerability Title
Jwcrypto: jwcrypto: general json jws kid binding bypass during jwkset verification
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the jwcrypto library, which is used for implementing Javascript Object Signing and Encryption (JOSE) standards. The issue occurs when the library verifies a General JSON Serialization JWS using a set of keys. Due to a coding error, the library fails to correctly identify the specific key ID (kid) and may instead accept a signature made by any valid key in the set. This can allow an attacker with a valid key to bypass authorization checks in applications that rely on the key ID to identify specific tenants or users.
