Vulnerability Title
MISP Unauthenticated Mail Endpoints Allow Unbounded Storage Consumption and Request Flooding
Vulnerability Description
Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting.
The users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle.
The fix adds:
- a maximum email input length of 1024 bytes;
- email-format validation before persistent work;
- a per-source pre-authentication request budget;
- HTTP 429 responses when that budget is exceeded;
- a 15-minute cooldown for API-access request emails;
- POST-only handling and CSRF protection for the API-access request endpoint.
The new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts.
Version affected: ≤2.5.45

Vulnerability Title
MISP 资源管理错误漏洞
Vulnerability Description
MISP是MISP组织开源的一个威胁情报共享与分析平台。 MISP 2.5.45及之前版本存在资源管理错误漏洞,该漏洞源于users/forgot password-reset端点对攻击者控制的电子邮件参数未进行长度限制和格式验证,且缺少速率限制,导致该参数被持久化存储多次,可能导致资源耗尽和拒绝服务。
