Vulnerability in Theotherphil Imagecli

CVE-2026-70377

imagecli's pipeline operation (Scale::apply in src/image_ops.rs) computes output width/height as (dimension as f32 * ratio) as u32 with no upper-bound validation on the CLI-supplied ratio, which is parsed via nom::number::complete::float with no range check. Any application embedding imagecli as a library and accepting user-controlled pipeline strings is remotely crashable with a single request.
