GHSA-8359-H9FX-J6V9 datamodel-code-generator vulnerable to arbitrary local file read via JSON-Schema `$ref` (`file://` and `../` traversal), bypassing `--no-allow-remote-refs`

Summary datamodel-code-generator resolves JSON-Schema $ref targets that point at the local filesystem without restricting them to the input/base directory and without honoring the remote-reference security control. In the default configuration, an attacker who controls an input schema a "paste yo...

datamodel-code-generator generates Pydantic v2 models, dataclasses, TypedDict, and msgspec.Struct from OpenAPI, JSON Schema, GraphQL, Avro, Protobuf, and raw JSON, YAML, or CSV. Prior to 0.62.0, datamodel-code-generator resolves JSON Schema $ref targets in...

CVE-2026-55389

The CVE affects datamodel-code-generator (pre-0.62.0), where JSON Schema $ref resolution in src/datamodel_code_generator/parser/jsonschema.py using is_url/_get_ref_body could read arbitrary local files (via file:// or ../ traversal) when --no-allow-remote-refs is not honored. This could expose se...

datamodel-code-generator vulnerable to SSRF via JSON-Schema `$ref` to HTTP URL (silent by default)

Summary JSON-Schema $ref values pointing at HTTP or HTTPS URLs are silently dereferenced by datamodel-code-generator with no IP/host validation, no scheme allow-list, and redirects followed unconditionally. The --allow-remote-refs gate added in 0.56.0 defaults to None, which only emits a...

GitHub MCP Server is GitHub's official MCP Server. Prior to 1.1.0, the CompletionsHandler function in pkg/github/server.go accesses params.Ref without first checking whether it is nil, so a completion/complete request with a missing or empty ref field triggers a nil pointer dereference and a Go...

CVE-2026-47427 GitHub MCP Server: Nil Pointer Dereference DoS in completion/complete Handler

GitHub MCP Server is GitHub's official MCP Server. Prior to 1.1.0, the CompletionsHandler function in pkg/github/server.go accesses params.Ref without first checking whether it is nil, so a completion/complete request with a missing or empty ref field triggers a nil pointer dereference and a Go...

CVE-2026-64266 fuse: re-lock request before returning from fuse_ref_folio()

In the Linux kernel, the following vulnerability has been resolved: fuse: re-lock request before returning from fusereffolio fusereffolio unlocks the request but does not re-lock it before returning. fusechanabort can end the request and the async end callback eg fusewritepagefree can free the ar...

CVE-2026-64266

CVE-2026-64266 affects the Linux kernel fuse subsystem. The vulnerability stems from fuse_ref_folio() unlocking the request but not re-locking before return, allowing fuse_chan_abort() to end the request and for the async end callback to free args while the copy chain later accesses them, causing...

PYSEC-2026-3509 PraisonAI GitHub template cache path traversal allows outside-cache file write and directory deletion

Summary PraisonAI's template loader accepts GitHub template URIs with refs, for example github:owner/repo/[email protected]. The resolver stores the user-controlled template path and ref verbatim, and the cache layer later joins those values into /.praison/cache/templates/github//// without...
