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.

受影响的 Flowintel 版本允许通过系统设置修改 配置值，且未将其限制在预期的日志目录内的文件名范围内。 由于应用程序根据该可配置值构建日志写入路径，管理员可以将 设置为任意文件系统路径。攻击者能够影响被记录的内容，从而能够将受控数据写入到非预期的文件中。上游提交特别描述了一条利用链：攻击者先将模板注入到选定的文件中，随后利用应用程序的渲染行为来执行代码。 该补丁做了以下改动： 从可通过网页编辑的设置中移除了 ； 引入了 函数，用于拒绝绝对路径、路径遍历（如 ）、Windows 风格路径、空字节以及包含目录成

Vulnerability Title
Flowintel Arbitrary Log File Path Allows Remote Code Execution via Template Injection
Source: CVE Program / CVE List V5
Vulnerability Description
Affected versions of Flowintel allow the LOG_FILE configuration value to be modified through system settings without restricting it to a filename inside the intended log directory. Because the application constructs the log destination from this configurable value, an administrator could set LOG_FILE to an arbitrary filesystem path. Since attackers can influence logged content, this enables controlled data to be written into unintended files. The upstream commit specifically describes an exploitation chain in which an attacker injects a template into a chosen file and subsequently abuses application rendering behavior to execute code. The patch removes LOG_FILE from the web-editable settings, introduces validate_log_file_name() to reject absolute paths, traversal, Windows paths, null bytes, and directory components, and centralizes log path construction through resolve_log_file_path(). Version impacted: >=3.3.0
