## What is CVE-2025-32025?

CVE-2025-32025 is a medium-severity denial of service vulnerability in bep imagemeta, published on 8 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

bep/imagemeta is a Go library for reading EXIF, IPTC and XMP image meta data from JPEG, TIFF, PNG, and WebP files. The buffer created for parsing metadata for PNG and WebP images was only bounded by their input data type, which could lead to potentially large memory allocation, and unreasonably high for image metadata. Before v0.11.0, If you didn't trust the input images, this could be abused to construct denial-of-service attacks. v0.11.0 added a 10 MB upper limit.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)

Check this codebase for CVE-2025-32025 and fix it if it is affected.

What it is: CVE-2025-32025 is a medium-severity denial of service vulnerability in bep imagemeta, published on 8 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2025-32025 in the wild and no public exploit code.

Affected packages and fixed versions:
- github.com/bep/imagemeta (Go): affected all versions; fixed in 0.11.0
- github.com/bep/imagemeta (Go): affected all versions; fixed in 0.11.0
- github.com/bep/imagemeta (Go): affected all versions; fixed in 0.11.0

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.
