Source: amazon-inspector (2940bc600ade9f91afdc44ccc04cdab589d276b0504b3f12ffb4a4e827920bd9) The gem ships a native-extension stub (extconf.rb) that `gem install` executes automatically, but no C/C++ sources accompany it and lib/sol_mint_utils.rb is an inert stub (defines VERSION and returns 'ok'). The README advertises an unrelated package name (`bitcoin-rpc-lite`), confirming the gem's declared purpose is a cover. extconf.rb base64-decodes a Ruby payload and eval's it inside a forked/detached process; the decoded payload opens a TCPSocket to the hardcoded host 45.138.12.177 on port 8089 and bridges a /bin/sh session over the socket via IO.popen and IO.copy_stream, granting the operator an interactive reverse shell on the installer's machine. Execution is gated by anti-analysis checks: CI environment variables, hostname patterns (uvm/firecracker/sandbox/vagrant), generated usernames, analysis working directories…

# Patch Next advisory brief: mal-2026-17795

Advisory: Malicious code in sol-mint-utils (RubyGems)
IDs: mal-2026-17795
Record: https://patchnext.com/advisories/mal-2026-17795 (revision 1, source checked 23 Oct 2026, 22:04 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- RubyGems sol-mint-utils: affected >= 0.9.1, <= 0.9.1

## Suggested inspection (read-only)
- RubyGems sol-mint-utils: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on sol-mint-utils.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/MAL-2026-17795 (OSV record MAL-2026-17795 lists affected ranges: RubyGems sol-mint-utils >=0.9.1 <=0.9.1)
