GHSA-F7WF-V2VW-MPCX mcp-memory-keeper: Arbitrary local file read in context_import via unvalidated filePath

Impact contextimport passed the caller-supplied filePath directly to fs.readFileSync with no path confinement. A malicious MCP client — or an LLM agent that is prompt-injected into calling the tool — could point filePath at any file readable by the server process, outside any session or export...

yutu: Arbitrary File Write via MCP `caption-download` Tool

Arbitrary File Write via MCP caption-download Tool Summary The caption-download MCP tool in yutu passes the caller-supplied file parameter directly to os.Create at pkg/caption/caption.go:272 without any path validation, canonicalization, or confinement to the pkg.Root boundary YUTUROOT. A local...

Name of the Vulnerable Software and Affected Versions yutu version 0.0.0-dev Description An arbitrary file write issue exists in the caption-download MCP tool. The tool fails to validate, canonicalize, or confine the file parameter to the intended YUTU ROOT boundary, passing it directly to the...

CVE-2026-50162

A flaw was found in oras-go. The file content store, intended to confine writes to a specified working directory, does not properly account for symbolic link symlink traversal. A remote attacker, by providing a specially crafted blob title, could exploit this vulnerability to create files outside...

PYSEC-2026-2894 PPTAgent: Arbitrary File Write via `save_generated_slides`

Summary This vulnerability has been fixed in https://github.com/icip-cas/PPTAgent/commit/418491a9a1c02d9d93194b5973bb58df35cf9d00. The savegeneratedslides MCP tool accepts a pptxpath argument and writes the generated PPTX file to that path without any workspace restriction or path validation:...

PT-2026-59213

Summary Several LangChain components that resolve filesystem paths or expand search patterns do not consistently confine the resolved path to the intended root directory. Affected behaviors include: a file-search agent middleware that validates a starting directory but not the search pattern or t...

GHSA-52VM-MXX8-F227 Phantom: Arbitrary file write and decode-bomb DoS via unconfined MCP tool paths

Impact In Phantom = 1.3.0, when PHANTOMOUTPUTDIR was unset the default, the MCP tools accepted arbitrary absolute output paths with no confinement. Anything able to send tool calls e.g. an AI agent driving the MCP interface could write or overwrite arbitrary files the process user can write —...

A filename containing an absolute path or travers...

CVE-2026-50135 Hugo: Symlink confinement bypass in resources.Get

Hugo is a static site generator. From 0.123.0 to 0.161.1, a regression made RootMappingFs.statRoot use Stat follows symlinks instead of Lstat , so a direct resources.Get of a symlink pointing outside its mount returned the target's contents — letting a symlink planted in a local mount e.g. a...

CVE-2026-50135

Summary: Hugo up to v0.161.1 is affected by a symlink confinement bypass in the virtual filesystem used by Hugo’s resources.Get. Root cause: A regression in RootMappingFs.statRoot caused it to call Stat (which follows symlinks) instead of Lstat, allowing a symlink inside a mounted directory (e.g....

CVE-2026-58403

Hugo (static site generator) vulnerable from v0.123.0 through v0.163.0. A regression in RootMappingFs.statRoot caused it to call Stat (which follows symlinks) instead of Lstat, enabling os.ReadFile on a symlink to read the target file outside the mount. This could let a symlink inside a theme or ...
