CVE-2026-28432
HighSummary
Misskey to otwartoźródłowa, federacyjna platforma mediów społecznościowych. Wszystkie serwery Misskey przed wersją 2026.3.1 zawierają podatność, która pozwala na ominięcie weryfikacji podpisu HTTP. Ta podatność dotyczy wszystkich serwerów, niezależnie od tego, czy federacja jest włączona, czy wyłączona.
Risk Assessment
Podatność ta może prowadzić do nieautoryzowanego dostępu do danych oraz manipulacji komunikacją między serwerami, co stanowi poważne zagrożenie dla bezpieczeństwa organizacji.
Recommendation
Zaleca się aktualizację serwerów Misskey do wersji 2026.3.1 lub nowszej, aby usunąć tę podatność.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Prior to version 2.1.27, the SSE transport mode (`SSE=true`) exposes all MCP tools without any authentication. The `upload_markdown` tool reads arbitrary files from the server's local filesystem via an unsanitized `file_path` parameter and uploads them to a GitLab project.

`@zereight/mcp-gitlab` is a Model Context Protocol server for GitLab. Versions prior to 2.1.30 expose the Streamable HTTP MCP endpoint without an effective Host or Origin allowlist. A malicious web page can use DNS rebinding to route browser requests to a victim's local MCP listener while preserving an attacker-controlled `Host` and `Origin`.
Original NVD description (English source)
Misskey is an open source, federated social media platform. All Misskey servers prior to 2026.3.1 contain a vulnerability that allows bypassing HTTP signature verification. Although this is a vulnerability related to federation, it affects all servers regardless of whether federation is enabled or disabled. This vulnerability is fixed in 2026.3.1.
