PYSEC-2026-1430 GuardDog Path Traversal Vulnerability Leads to Arbitrary File Overwrite and RCE
Summary A path traversal vulnerability exists in GuardDog's safeextract function that allows malicious PyPI packages to write arbitrary files outside the intended extraction directory, leading to Arbitrary File Overwrite and Remote Code Execution on systems running GuardDog. CWE: CWE-22 Improper...
PYSEC-2026-1787 picklescan has Arbitrary file read using `io.FileIO`
Summary Unsafe pickle deserialization allows unauthenticated attackers to read arbitrary server files and perform SSRF. By chaining io.FileIO and urllib.request.urlopen, an attacker can bypass RCE-focused blocklists to exfiltrate sensitive data example: /etc/passwd to an external server. Details...
AIOHTTP's unicode processing of header values could cause parsing discrepancies
SummaryThe Python HTTP parser may allow a request smuggling attack with the presence of non-ASCII characters. ImpactIf a pure Python version of aiohttp is installed i.e. without the usual C extensions or AIOHTTPNOEXTENSIONS is enabled, then an attacker may be able to execute a request smuggling...

PYSEC-2026-2000 Universal Tool Calling Protocol (UTCP) client library for Python vulnerable to Trust Boundary Violation through Manual JSON specification
The vulnerability arises when a client fetches a tools’ JSON specification, known as a Manual, from a remote Manual Endpoint. While a provider may initially serve a benign manual e.g., one defining an HTTP tool call, earning the clients’ trust, a malicious provider can later change the manual to...
Model Context Protocol (MCP) Python SDK does not enable DNS rebinding protection by default
DescriptionThe Model Context Protocol MCP Python SDK does not enable DNS rebinding protection by default for HTTP-based servers. When an HTTP-based MCP server is run on localhost without authentication using FastMCP with streamable HTTP or SSE transport, and has not configured...
Peppol-py is vulnerable to XXE attacks due to Saxon configuration
