Write Once, Shell Everywhere: Turning Arbitrary File Writes into RCE
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
A graded catalogue of arbitrary-file-write to RCE sinks, plus new ones. Path resolution stops at the first failing component, so the errno of a failed write - read through status code, body length or latency - fingerprints OS, container, distro and runtime version. Guess-free targets follow: PID 1's still-open entrypoint script at /proc/1/fd/255 or /proc/1/fd/10, a worker pool's fixed worker.js, and Rails db/schema_cache.yml, unsafe_load'd into a RubyGems hash-key gadget chain.
