Vulnerability Title
Flowintel Login Email Validation Bypass Allows Log Injection via Crafted Email Input
Vulnerability Description
Affected versions of Flowintel incorrectly attempted to validate login email addresses by calling Email(email). That does not perform WTForms field validation; it merely constructs a validator object.
Consequently, malformed attacker-controlled email input could continue through the login process and be written to security-relevant logs. The vulnerable code inserted the supplied email into both a warning log and the custom audit logger. Since CR/LF characters were not escaped, an unauthenticated attacker could potentially inject additional physical log lines or forge misleading log entries.
The patch corrects the validation call to Email()(form, form.email), changes the standard logging call to parameterized logging, and introduces _sanitize_log_fragment() so carriage returns and line feeds are encoded instead of creating new records.
Version impacted >=3.3.0

Vulnerability Title
flowintel 输入验证错误漏洞
Vulnerability Description
flowintel是flowintel团队开源的一款威胁情报与威胁分析管理平台。 flowintel 3.3.0及之前版本存在输入验证错误漏洞,该漏洞源于调用Email(email)校验登录邮箱地址时未正确执行WTForms字段验证,导致格式错误的邮箱输入通过登录流程并写入安全日志,且未转义CR/LF字符,可能允许未经身份验证的攻击者注入日志行或伪造误导性日志条目。
