CVE-2026-70377
imagecli: Uncontrolled Memory Allocation via Unbounded scale Ratio Causes Denial of Service
CVSS Score
7.5
EPSS Score
0.0%
EPSS Percentile
0th
imagecli's `scale <ratio>` 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. A large ratio (e.g. 100000) causes an attempted allocation of hundreds of terabytes, aborting the process. Any application embedding imagecli as a library and accepting user-controlled pipeline strings is remotely crashable with a single request.
