Disclosure summary
A user account with permission to deploy artifacts to a hosted Maven repository could upload a POM file containing an oversized metadata field. This causes future attempts to list or browse that repository's components to permanently fail until an administrator repairs the underlying data. Only the targeted repository is affected; other repositories and overall server health remain unaffected.

GitHub repository matches
Repository matches are links and GitHub-supplied metadata only. They are not verified working proof-of-concept code. Each supported query is bounded to ten pages and at most 1,000 indexed results. This is not a complete index of GitHub or public exploit research. Coverage can also be limited by provider availability, rate limits, rejected metadata, incomplete search results, manual review, and the recorded refresh time.
