Security fixes are applied to the latest version published on master (see VERSION).
Do not open a public issue. Use GitHub's private reporting: open the Security tab of the repository, then Report a vulnerability.
Include the SecondBrain version, the steps to reproduce the problem and the expected impact. Do not attach real secrets, tokens or personal data: replace them with dummy values.
Replies are sent in the same private conversation. The fix is published before the details are disclosed.
SecondBrain is a local tool: the PowerShell scripts, the read-only MCP server (scripts/mcp-server.ps1) and the IDE configuration files it generates. Vulnerabilities in the IDEs, Git or PowerShell themselves are out of scope.
