# Security Policy ## Supported versions Security fixes land in the latest release. Please reproduce against a recent release or `master` before reporting; issues that only reproduce on old, unsupported versions are not eligible for a fix or an advisory. ## Reporting a vulnerability Report privately through GitHub private vulnerability reporting (the "Report a vulnerability" button under the repository's Security tab). This keeps the report, the fix, and any CVE in one place. Do not open a public issue. ### What a report must include We can only act on reports that show real impact. Please include: - Affected version (a release tag or `master` commit you reproduced on) - The exact deployment and configuration: which components are running (master, volume, filer, S3, admin), which ports are reachable by the attacker, and what authentication is enabled - The attacker's starting position: unauthenticated, a valid S3 user, an admin, or someone with access to the internal cluster network - The trust boundary that is crossed (e.g. an unauthenticated client reading another tenant's data, an S3 user escalating to admin) - A minimal, working reproduction or proof of concept - Expected vs. actual behavior A report without a working reproduction and a clear trust boundary is a hardening suggestion, not a vulnerability. We are glad to receive those, but they are handled on the normal issue tracker, not as security advisories. ### Automated and AI-assisted reports Output from static analysis, dependency scanners, fuzzers, or LLMs is welcome only when you have manually validated it and can supply a working reproduction against a supported version, per the requirements above. Raw tool output, speculative findings, or generated reports without a demonstrated exploit will be closed as hardening suggestions. ## Trust model SeaweedFS is built to run with its cluster components (master, volume servers, and the raw filer API) on a trusted network. Those internal APIs are not an authentication boundary unless you explicitly enable a control (for example volume JWT or filer authentication) and that control is bypassed. Exposing an internal port directly to untrusted clients is a deployment mistake, not a vulnerability in SeaweedFS. Reports are in scope when they cross a boundary SeaweedFS is meant to enforce, for example: - Unauthenticated access to data or operations that require authentication - One S3 identity reading, writing, or deleting another identity's data - Privilege escalation from a normal S3 user to administrative capability - Bypass of Object Lock / retention where it is configured - Remotely triggered data corruption or loss Reports are generally out of scope when they require: - Direct access to an internal cluster port that is meant to be private - Full master, filer, or volume server access (already a full compromise) - An insecure example configuration rather than a documented secure setup - Local-only impact on a host the attacker already controls ## CVE assignment When a report is confirmed, we publish an advisory and request the CVE through GitHub. CVEs assigned by third parties without coordinating with us, or for issues that do not cross a boundary described above, may be disputed. ## Response and disclosure - We aim to acknowledge a valid report within a few business days. - We will investigate, work on a fix, and coordinate a disclosure timeline with you. - Please allow time for a fix before any public disclosure.
