<h2>Reporting Vulnerabilities</h2>
|
|
<p>Please do not disclose security vulnerabilities publicly before coordinate disclosure. If you identify a potential security issue in ChronoSeal, contact the maintainers privately.</p>
|
|
<p>When reporting, please include the following details to assist our review:</p>
|
|
<ul>
|
|
<li>Detailed description of the issue and potential impact.</li>
|
|
<li>Step-by-step reproduction guide or proof-of-concept (PoC) script.</li>
|
|
<li>Affected versions of the daemon, WASM package, or shared components.</li>
|
|
<li>Any proposed mitigations or code patches.</li>
|
|
</ul>

|
<strong>Do not file public GitHub issues for security vulnerabilities.</strong> Email or message the project maintainers directly via security contacts defined in the project repository.

<h2>Project Scope</h2>
|
|
<p>ChronoSeal operates as a cost-raising security layer, specifically:</p>
|
|
<ul>
|
|
<li><strong>Anti-scraper middleware:</strong> Restricts low-resource, simple command-line scripts and scrapers.</li>
|
|
<li><strong>Behavioral attestation layer:</strong> Asserts basic input sanity signals.</li>
|
|
<li><strong>Cryptographic continuity verifier:</strong> Guarantees that heartbeats progress chronologically along a server-controlled path.</li>
|
|
</ul>
|
|
<p>We actively harden the following boundaries and welcome reports regarding:</p>
|
|
<ul>
|
|
<li>Bypassing the hash-chain sequence without having session secrets.</li>
|
|
<li>Replaying previously accepted heartbeat requests.</li>
|
|
<li>Causing server panics, database memory leaks, or execution exhaustion.</li>
|
|
<li>Bypassing stateful synthetic gene mutations.</li>
|
|
<li>Security response header bypasses or CSP evasion.</li>
|
|
</ul>
|
|
|
|
<h2>Hardened Security Features (v1.0.2)</h2>
|
|
<p>The latest version includes the following security hardening implementations:</p>
|
|
<ul>
|
|
<li><strong>Sanitized Fingerprints:</strong> Strict validation of aspect ratio, DPR, and CPU concurrency limits to reject malformed inputs.</li>
|
|
<li><strong>Stack-Depth Protection:</strong> Bounded stack limits (capped at 512) to prevent VM buffer overflows.</li>
|
|
<li><strong>DashMap Rate Limiter:</strong> Hardened concurrent rate limiting to mitigate denial-of-service attempts.</li>
|
|
<li><strong>Response Headers:</strong> Automatic inject of Content-Security-Policy (CSP), X-Frame-Options, and Referrer-Policy headers to secure browser pages.</li>
|
|
</ul>
