CVE-2026-3515— Prefect 参数注入漏洞

Argument Injection in prefecthq/prefect

A vulnerability in the `GitHubRepository` block of the `prefect-github` integration in Prefect version 3.6.18 allows an attacker to inject arbitrary git command-line options via the `reference` field. The `reference` field is concatenated directly into a `git clone` command string without proper sanitization, and then parsed by `shlex.split()`. This enables injection of options such as `-c`, leading to potential Server-Side Request Forgery (SSRF), credential theft, or remote code execution (RCE). The vulnerability affects both the `aget_directory()` and `get_directory()` methods in `src/integrations/prefect-github/prefect_github/repository.py`. This issue does not affect the GitLab and BitBucket integrations, which use a safer list-based command construction approach.

Prefect 参数注入漏洞

Prefect是Prefect开源的一款工作流编排工具，使开发人员能够构建、观察数据管道并对数据管道做出反应。 Prefect 3.6.18版本存在参数注入漏洞，该漏洞源于prefect-github集成中GitHubRepository块的 reference 字段被直接拼接到git clone命令字符串中且未进行适当清理，可能导致攻击者注入任意git命令行选项，进而导致服务端请求伪造、凭据窃取或远程代码执行。
