CVE-2026-70377Public exploitNetwork attack vector

Process crash via unbounded scale ratio

Published Aug 5, 2026 · Updated Aug 5, 2026

Uncontrolled memory allocation in the scale operation in theotherphil imagecli 0.2.1 and earlier allows attackers to crash the process via a large ratio. Scale::apply in src/image_ops.rs multiplies both image dimensions by an unbounded pipeline ratio and passes the resulting sizes to DynamicImage::resize. CLI execution requires an attacker-influenced pipeline string; an unauthenticated remote crash requires a service that embeds the library and accepts that string.
