Amounts are the top reward per severity in the currency each program pays. First response is the platform's measured average when it publishes one, else what the policy promises.

What is in scope

8 targets. 7 excluded.

  • https://karapace.io

    Web

  • Authentication and ACL enforcement, since Karapace is frequently the only thing standing between an HTTP client and a Kafka cluster

    Products and areas

  • Avro, JSON Schema and Protobuf schema parsing, and the compatibility checking that decides whether a new schema may replace an old one

    Products and areas

  • The _schemas compacted-topic backing store and the consistency handling that keeps registry state coherent across instances

    Products and areas

  • The Kafka REST proxy, meaning the HTTP-to-Kafka bridge that produces and consumes on a caller's behalf, including its consumer-group handling

    Products and areas

  • The published container images and the Python package as distributed

    Products and areas

  • The Schema Registry API in full: the subject, version, config and compatibility endpoints, and the authorization model in front of them

    Products and areas

  • What the program declares: vulnerabilities in Aiven open source code, with github.com/Aiven-Open listed as a target. Karapace sits at github.com/Aiven-Open/karapace, so the whole repository is covered at P1 $1,000 to $1,500, and the project's own SECURITY.md sends reporters to the same program.

    Products and areas

No target matches. Try part of a host name, such as the company name.

Out of scope 7

Don't test these. A program can exclude a host another program covers; the program you report to decides.

  • Anything also present in an upstream repository that Karapace forked from, which belongs with that upstream project

  • Anything other than the most recent release, which is the only version the program will grade

  • Application-level denial of service, excluded by the program's baseline for all targets

  • Issues previously reported to Aiven through any channel other than Bugcrowd, which the program refuses on its face

  • Missing security headers, TLS configuration choices, and SPF, DKIM or DMARC best-practice reports

  • Software-version banner disclosure and descriptive error messages

  • Theoretical findings with no working, Karapace-specific proof of concept
