CVE-2026-44716— Pipecat 路径遍历漏洞

Pipecat: Path Traversal in Pipecat Runner `/files` Endpoint — Arbitrary File Read via `%2F`-Encoded Separator

Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. From version 0.0.90 to before version 1.2.0, a path traversal vulnerability exists in Pipecat's development runner (src/pipecat/runner/run.py). When the runner is started with the --folder flag, it exposes a GET /files/{filename:path} download endpoint. The filename path parameter is concatenated directly onto args.folder with no containment check. Starlette normalises literal ../ sequences in URLs, but %2F-encoded slashes bypass this normalisation: the path parameter is URL-decoded after routing, so ..%2F..%2Fetc%2Fpasswd resolves to a path two levels above args.folder. An attacker with network access to the runner can read any file the pipecat process has permission to access — including SSH private keys, credentials, and system files — with a single unauthenticated HTTP request. This issue has been patched in version 1.2.0.

对路径名的限制不恰当(路径遍历)

Pipecat 路径遍历漏洞

Pipecat是Pipecat开源的一个支持实时音视频流处理与AI对话交互构建的开发框架。 Pipecat 0.0.90版本至1.2.0之前版本存在路径遍历漏洞，该漏洞源于开发运行器中路径遍历问题，当使用--folder标志启动时，GET /files/{filename:path}下载端点将文件名路径参数直接连接到args.folder上且未进行包含检查，攻击者可通过网络访问读取任意文件。
