48.0.5

Released 2026-10-02.

Fixed

  • Fixed an issue where artifacts for 48.0.4 didn't get correctly published from CI and a GitHub release for 48.0.4 wasn't made. #14494

48.0.4

Released 2026-10-02.

Fixed

  • WASI preview 0 implementation of poll_oneoff circumvents fuel consumption. GHSA-j366-h8gg-77pm

  • Excessive allocated memory on the host when guests don't have stdio. GHSA-gqmc-89g8-p25r

  • fd_readdir copies uninitialized struct padding into guest memory. GHSA-96f6-r43r-8c24

  • Guest can panic host through filesystem timestamp before the epoch on wasip3. GHSA-mr2v-56j5-cmfc

  • Wasmtime component async-lifted callback result count is unvalidated, causing a native stack buffer overflow. GHSA-32h6-97mm-8q3c

  • Mis-typed WebAssembly tag imports can lead to GC heap corruption. GHSA-cfhf-m2cr-62wj

  • Wasmtime wasi:http implementation panics with a zero timeout supplied. GHSA-w4qr-p94g-mjhv

  • Rooting for GC values live across try_call may be missing, causing GC heap corruption. GHSA-hw8m-q44c-ggrf
