## What is CVE-2025-55005?

CVE-2025-55005 is a medium-severity memory corruption vulnerability in Imagemagick Imagemagick, published on 13 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, when preparing to transform from Log to sRGB colorspaces, the logmap construction fails to handle cases where the reference-black or reference-white value is larger than 1024. This leads to corrupting memory beyond the end of the allocated logmap buffer. This issue has been patched in version 7.1.2-1.

Weakness: CWE-122 (Heap-based Buffer Overflow)

Check this codebase for CVE-2025-55005 and fix it if it is affected.

What it is: CVE-2025-55005 is a medium-severity memory corruption vulnerability in Imagemagick Imagemagick, published on 13 Aug 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-55005 exists.

Affected product: Imagemagick Imagemagick. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
