GitHub Actions + Rust's Miri can leak your secrets in CI 🧵 If you run Miri in CI: - upgrade to the 2026-09-22 nightly - clear caches - rotate any secrets that the `cargo miri` CI job had access to GPT-6 Astra helped find this 🦀

GitHub Actions makes it possible to cache directories between runs. Typical setups allow CI runs on main (and other branches) to write to cache, and PRs can only read from cache (preventing cache poisoning). Rust projects tend to speed up CI by caching binaries built by cargo install and sometimes the contents of target/.

PR CI can be triggered by anyone who can open PRs on your repository. GitHub requires maintainer approval for the first PR, but future PRs will rerun CI on every push. Anyone who has previously landed a change can trigger a CI run extracting information from cached target/ and then cover their tracks by pushing a second commit to the PR.

GitHub sometimes hides overwritten commits in its UI, making this kind of attack harder to detect. CI run logs and overwritten commits are also deleted after a few months.

When cargo miri is invoked, Miri needs to retain build-relevant environment variables between runs. The current code to do so achieves this by storing all environment variables to target/. This, of course, persists when target/ is cached.

If your environment contained secrets, these can now be accessed by PRs via the cache.

This week I received a Deimos DAQ Rev7 from @deimoscontrols.bsky.social It acquires precision measurement, here from two thermocouples, and can use these to control outputs, here a GPIO pin. All controllable from #Rust (or python). Thanks @ponderingpothos.bsky.social for all your help!

New blog post for the WebGPU aficionados! WGSL layout rules are annoying, and I got tired of mismatched CPU/GPU layouts (because the failure mode usually required rebooting my entire laptop) As it turns out, it's not too hard to automatically cross-check them, with the power of runtime reflection!

screenshot from C11 standard, appendix J.2, specifying that "The behavior is undefined in the following circumstances:
— A ‘‘shall’’ or ‘‘shall not’’ requirement that appears outside of a constraint is violated
(clause 4).
— A nonempty source file does not end in a new-line character which is not immediately
preceded by a backslash character or ends in a partial preprocessing token or
