## What is GHSA-qg8r-f7x3-25f7?

GHSA-qg8r-f7x3-25f7 is a memory corruption vulnerability in imageproc, published on 1 May 2026. 

### Official description

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered `NaN` cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected projection matrix.

Carefully controlling the coordinates of an image with no data and one non-zero dimension provides an arbitrary read primitive in the first 32-bits of address space with a Bilinear sampling method.

Using bicubic sampling can result in a read of a few bytes beyond an allocation.

Other out-of-bounds reads may be possible.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
