# Security Policy DSH Plugin Store discovers and can install third-party DeepSeek Harness plugins. That makes catalog integrity, repository validation, install approval, and dependency execution part of its security boundary. ## Supported versions The project is currently a source preview developed against DeepSeek Harness `0.1.0-rc.5`. Security fixes are applied to the latest commit on `main` and the latest GitHub prerelease. No stable package line is supported yet. ## Report a vulnerability privately Do not open a public issue for a vulnerability or include credentials, private repository names, internal paths, exploit details, or sensitive logs in a Discussion. Use GitHub's [private vulnerability reporting](https://github.com/sandbaseai/dsh-plugin-store/security/advisories/new) to contact the maintainers. Include: - the affected commit or prerelease; - the trust boundary that is crossed; - minimal reproduction steps; - expected and actual behavior; - impact and any known mitigations; - sanitized logs or screenshots when useful. We will acknowledge a valid report, investigate it, coordinate remediation, and publish an advisory when disclosure is appropriate. Please allow a reasonable remediation window before public disclosure. ## Security boundaries - Catalog metadata is discovery data, not a security endorsement. - A repository appearing in the catalog does not prove compatibility, quality, maintainer identity, or absence of malicious code. - Installing a plugin may fetch and execute third-party code and package lifecycle scripts with the permissions of the local DSH process. - The native installer validates repository identifiers and requires entries to originate from the configured catalog, but those checks do not replace source review, signature verification, sandboxing, or organizational policy. - Agent tools return reviewed installation guidance by default; they must not be treated as permission for silent environment mutation. - Enterprise deployments should use an approved private catalog or allowlist, isolate execution, control credentials and egress, and retain installation and configuration audit events. ## Out of scope General defects, listing corrections, feature requests, and non-sensitive compatibility failures should use the public issue tracker. Vulnerabilities in a listed third-party plugin should be reported to that plugin's maintainers unless the Store itself introduces or amplifies the issue.
