Resolves Dependabot alert 9 (GHSA-x2f5-4prf-w687 / CVE-2026-54696), a low-severity heap buffer overflow in the json gem's IO-streaming generator path. The gem is a transitive dependency of `package_cloud` used only by the CI release tooling, and 2.21.2 satisfies the existing `json (~> 2.9)` constraint.

Resolves Dependabot alert 9 (GHSA-x2f5-4prf-w687 / CVE-2026-54696), a low-severity heap buffer overflow in the
jsongem. The flaw is a heap out-of-bounds write in the IO-streaming generator path (JSON.dump(obj, io)andJSON::State#generate(obj, io)) when a streamed string sits near the 16 KB internal buffer boundary, with a demonstrated impact of a denial-of-service crash. The vulnerable range is>= 2.9.0, < 2.19.9and the first patched release is2.19.9.In this repository
jsonis a transitive dependency ofpackage_cloud, which together withfpmis used only by the CI release tooling that builds and publishes the Debian package, so it is not part of the runtime of the shippedsshcommandscript. This bumps the locked version to the latest 2.x release,2.21.2, which resolves the advisory while continuing to satisfy the existingjson (~> 2.9)constraint.
