PYSEC-2026-1623 mcp-server-git has missing path validation when using --repository flag

In mcp-server-git versions prior to 2025.12.18, when the server is started with the --repository flag to restrict operations to a specific repository path, it did not validate that repopath arguments in subsequent tool calls were actually within that configured path. This could allow tool calls t...

PYSEC-2026-1621 mcp-server-git's unrestricted git_init tool allows repository creation at arbitrary filesystem locations

In mcp-server-git versions prior to 2025.9.25, the gitinit tool accepted arbitrary filesystem paths and created Git repositories without validating the target location. Unlike other tools which required an existing repository, gitinit could operate on any directory accessible to the server proces...

PYSEC-2026-1994 urllib3 streaming API improperly handles highly compressed data

Impact urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. When streaming a compressed response, urllib3 can perform decoding or decompression based on the HTTP...

urllib3 allows an unbounded number of links in the decompression chain

Impacturllib3 supports chained HTTP encoding algorithms for response content according to RFC 9110 e.g., Content-Encoding: gzip, zstd.However, the number of links in the decompression chain was unbounded allowing a malicious server to insert a virtually unlimited number of compression steps leadi...

PYSEC-2026-1135 Apache Airflow has a command injection vulnerability in "example_dag_decorator"

An example dag exampledagdecorator had non-validated parameter that allowed the UI user to redirect the example to a malicious server and execute code on worker. This however required that the example dags are enabled in production not default or the example dag code copied to build your own...

PYSEC-2026-1906 Scrapy is vulnerable to a denial of service (DoS) attack due to flaws in brotli decompression implementation

Scrapy versions up to 2.13.3 are vulnerable to a denial of service DoS attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of...

Apache Doris-MCP-Server: Improper Access Control results in bypassing a "read-only" mode

An attacker with a valid read-only account can bypass Doris MCP Server’s read-only mode due to improper access control, allowing modifications that should have been prevented by read-only restrictions.Impact:Bypasses read-only mode; attackers with read-only access may perform unauthorized...

PYSEC-2026-1077 Agno session state overwrites between different sessions/users

Impact Under certain conditions under high concurrency, when sessionstate is passed to an Agent or Team during run or arun calls, a race condition can occur, causing a sessionstate to be assigned and persisted to the incorrect session. This may result in user data from one session being exposed t...
