Scope

7 assets you may test, 9 excluded.

Web 1

  • https://azure.github.io/azure-sdk-for-python

Products and areas 6

  • azure-core: the sync and async HTTP pipelines, every policy on them, the transport adapters and the tracing hooks each generated client inherits
  • azure-identity: every credential type, the chained credentials, managed and workload identity, the CLI and environment fallbacks, and the token cache
  • The azure-mgmt-* control-plane clients, and the shared serialization and azure-common code the generator emits against
  • The generated service clients across the whole catalogue, azure-storage-*, Key Vault, Cosmos, Service Bus, Event Hubs, App Configuration and the rest: request construction, URL and SAS handling, and response deserialization
  • The repository's own build, release and publish GitHub Actions workflows, which the program prices in a band of their own
  • The whole of azure/azure-sdk-for-python, which the program names on its SCOPE list under "Azure SDKs, limited to the following", at Critical or Important severity on the most recent actively maintained branch
Out of scope (9)
  • Azure service-side defects, which belong to the Microsoft Azure bounty program
  • Findings whose impact stays on the local machine, since this repository sits outside the carve-out Microsoft grants to VS Code, Agent Framework, TypeScript, Monaco Editor and PowerShell
  • Hackathon repositories and dependency-confusion reports
  • Microsoft and Azure repositories outside the program's fifteen-entry SCOPE list: the standard SECURITY.md pointing at MSRC is a reporting path and funds nothing
  • Moderate and Low severity, which pay $0 at every report quality
  • Publicly disclosed issues
  • Reports Microsoft cannot pay out on: residency in a sanctioned country, or no IRS tax form returned within 30 days of validation, voids the award
  • Samples, tutorials, quickstart code and samples/ directories
  • Upstream PyPI dependencies the SDK consumes rather than owns

Rules

What the policy asks of you, and the bug types it won't reward, quoted from Sorona's policy.

While testing

  • Submit through sorona.xyz first.
  • Only the eight repositories listed under "Azure SDKs, limited to the following" qualify; no other Azure repository is covered, however similar it looks
  • Azure service-side defects belong to the separate Microsoft Azure bounty program, not this one, so the bug has to live in the client library
  • This repo is not in the local-machine carve-out, so local-machine-only impact is excluded
  • Only Critical and Important severity qualify on the most recent actively maintained branch; Moderate and Low findings pay $0
  • Follow coordinated vulnerability disclosure: Microsoft requires bounty submissions stay confidential while it fixes, and imposing a fix deadline forfeits eligibility
  • Return an IRS tax form (W-9, W-8BEN or 8233) within 30 calendar days of validation, and expect sanctions screening

Not accepted

  • Azure service-side defects
  • Upstream PyPI dependencies the SDK consumes rather than owns
  • Findings whose impact stays on the local machine
  • Moderate and Low severity
  • Samples, tutorials, quickstart code and samples/ directories
  • Hackathon repositories and dependency-confusion reports
  • Publicly disclosed issues

Credential-chain and token-handling defects here are cross-tenant by nature rather than by accident, which is exactly why the two most serious historical CVEs in the family, CVE-2024-35255 and CVE-2023-36414, were both identity bugs. Microsoft pays it through the MSRC Researcher Portal on the Open Source Bounty Program, where authentication issues top out at $12,000 for a high-quality Critical report and the $15,000 band needs deserialization or code injection. sorona.xyz adds 1.25x on top of whatever Microsoft awards, up to $1,000 more, plus a complexity bonus of up to $1,000 for a well-chained finding.

Azure SDK fixes are published through the Microsoft Security Update Guide rather than as repository advisories, so the public record and the credit appear there once fixed packages are on PyPI. Microsoft requires bounty submissions stay confidential while it fixes, so file with MSRC yourself first, hold publication until that record appears, and send sorona.xyz the case ID.
