Email aveproject.org@gmail.com. Please do not open a public issue for a security report until a fix is available; give a reasonable window to respond before public disclosure, informally 90 days unless the report itself indicates something actively being exploited, in which case sooner coordinated disclosure is appropriate.
This service is read-only, unauthenticated, and serves only public data already published in aveproject/ave. There is no user data, no write path, and no secrets held by this service beyond standard deployment credentials. Rate limiting (60 requests/minute per IP) is in place as a basic abuse backstop; a report that this can be bypassed is a valid, in-scope finding. Reports of highest value: anything that could turn this into a write path, an SSRF vector (this service does make one outbound fetch, to a fixed, hardcoded GitHub raw content URL, not user-controlled), or a denial-of-service vector beyond what the existing rate limiting already mitigates.
A misclassification, wrong severity, or incorrect field in an AVE record itself is a data-quality issue with the standard, not a security vulnerability in this API. Report those to aveproject/ave instead.
