Security Bulletin: Langflow is vulnerable to stored cross-site scripting and IP spoofing due to unsanitized Markdown rendering and untrusted proxy header trust

Summary Langflow contains two vulnerabilities affecting client-side security and access control integrity. The MarkdownField component renders chat messages using the rehypeRaw plugin without a sanitization pass, causing attacker-controlled LLM response text containing raw HTML to be inserted...

Security Bulletin: Langflow is vulnerable to information disclosure due to cross-user MCP tool cache collision and incomplete secret scrubbing on public flows

Summary Langflow contains two authenticated information disclosure vulnerabilities. The MCP Tools component caches discovered tools in a shared process-local cache keyed only by the MCP server display name without including the user, session, flow, or resolved configuration; when two authenticate...

CVE-2026-82021

Hermes Agent 0.18.2 prior to 0.19.0 contains a supply chain vulnerability in its bundled MCP catalog that allows a remote attacker to execute arbitrary code by compromising a third-party upstream repository referenced via a mutable branch rather than a pinned commit SHA. An attacker who compromis...
