CVE-2026-26284 is a medium-severity memory corruption vulnerability in Imagemagick Imagemagick, published on 24 Feb 2026. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, ImageMagick lacks proper boundary checking when processing Huffman-coded data from PCD (Photo CD) files. The decoder contains an function that has an incorrect initialization that could cause an out of bounds read. Versions 7.1.2-15 and 6.9.13-40 contain a patch. Weakness: CWE-125 (Out-of-bounds Read), CWE-787 (Out-of-bounds Write), CWE-122 (Heap-based Buffer Overflow) ## Which versions are affected by CVE-2026-26284? 38 open source packages ship an affected version, including Magick.NET-Q16-AnyCPU, Magick.NET-Q16-HDRI-AnyCPU and Magick.NET-Q16-HDRI-OpenMP-arm64.

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.
