Arrayref
Monthly
Build-time malicious code execution in the arrayref Rust crate version 0.3.10 allows an attacker to run arbitrary code on any developer or CI machine that compiles a project depending on it. The compromised release pulls in a rogue transitive dependency that beacons to a command-and-control server and accepts arbitrary command execution, making this a confirmed supply-chain compromise disclosed by the Rust Security Response WG and RustSec (RUSTSEC-2026-0260). No public standalone exploit is needed because the crate itself is the payload; not currently listed in CISA KEV.
