Halloy has a file transfer path traveral vulnerability

Halloy is an IRC application written in Rust. Prior to commit 0f77b2cfc5f822517a256ea5a4b94bad8bfe38b6, the DCC receive flow did not sanitize filenames from incoming `DCC SEND` requests. A remote IRC user could send a filename with path traversal sequences like `../../.ssh/authorized_keys` and the file would be written outside the user's configured `save_directory`. With auto-accept enabled this required zero interaction from the victim. Starting with commit 0f77b2cfc5f822517a256ea5a4b94bad8bfe38b6, all identified code paths sanitize filenames through a shared `sanitize_filename` function.

对路径名的限制不恰当(路径遍历)

Halloy 路径遍历漏洞

Halloy是Squidowl开源的一个跨平台IRC客户端。 Halloy存在路径遍历漏洞，该漏洞源于DCC接收流程未清理文件名，可能导致路径遍历和任意文件写入。
