CVE-2026-49290— Slopsmith has path traversal in archive extractors that allows arbitrary file write → potential RCE

Slopsmith has path traversal in archive extractors that allows arbitrary file write → potential RCE

Slopsmith is a self-contained web application for browsing, playing, and practicing Rocksmith 2014 Custom DLC (CDLC). Prior to 0.2.9-alpha.5, a path-traversal vulnerability in Slopsmith's archive extractors allows an attacker to write arbitrary files outside the extraction directory by supplying a crafted PSARC or sloppak archive. With the default Docker configuration (running as root) and the ability to drop a file into the plugin directory, this escalates to arbitrary remote code execution on the host. Three archive extractors concatenated archive-entry filenames directly onto the extraction root without validation: `lib/psarc.py::unpack_psarc` — PSARC TOC filenames; `lib/patcher.py::unpack_psarc` — duplicate of the above in the patcher flow; `lib/sloppak.py::_unpack_zip` — bare `ZipFile.extractall()` with no member filter. Each accepts entry names containing `..` segments, absolute paths, or backslash separators. The Python `zipfile` module's default `extractall()` is documented as not preventing traversal when callers don't supply a member-filter callback. Version 0.2.9-alpha.5 patches the issue. Until updated, do not open PSARC or sloppak archives from untrusted sources, and do not expose the Slopsmith instance to the public internet. Docker users should also pull the latest image after the next slopsmith Docker image is published.

对路径名的限制不恰当(路径遍历)

Byron Gamatos Slopsmith 路径遍历漏洞

Byron Gamatos Slopsmith是Byron Gamatos个人开发者的一个吉他演奏与练习平台。 Byron Gamatos Slopsmith之前版本存在路径遍历漏洞，该漏洞源于存档提取器未经验证直接拼接文件路径，允许攻击者通过特制的PSARC或sloppak存档将文件写入提取目录之外，可能导致远程代码执行。
