## What is CVE-2026-58586?

CVE-2026-58586 is a critical vulnerability in ZAPAD Image::WebP, published on 24 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Image::WebP versions before 0.3.0 for Perl bundle a vulnerable version of libwebp.

Image::WebP does not link to the system libwebp. Instead, it uses a bundled copy of libwebp 0.3.0 (released 2013-03-20). That version has multiple known vulnerabilities, including CVE-2023-4863.

Any caller that decodes an untrusted WebP image reaches the bundled decoder. Because the library is compiled into the module, upgrading the system libwebp does not remediate this.

Weakness: CWE-1395 (Dependency on Vulnerable Third-Party Component)

Check this codebase for CVE-2026-58586 and fix it if it is affected.

What it is: CVE-2026-58586 is a critical vulnerability in ZAPAD Image::WebP, published on 24 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-58586 in the wild and no public exploit code.

Affected product: ZAPAD Image::WebP. 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.
