## What is CVE-2026-58469?

CVE-2026-58469 is a high-severity memory corruption vulnerability in gnuwget wget, published on 7 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

GNU Wget through 1.25.0, fixed in commit 37a40fc, contains a heap buffer underread vulnerability in the clean_metalink_string() function within src/metalink.c that allows a malicious server to trigger memory corruption by serving a Metalink document containing a whitespace-only URL. Attackers can cause the function to decrement a pointer past the start of the buffer when processing an all-whitespace Metalink URL, potentially leading to abnormal program behavior.

Weakness: CWE-125 (Out-of-bounds Read)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-58469 and fix it if it is affected.

What it is: CVE-2026-58469 is a high-severity memory corruption vulnerability in gnuwget wget, published on 7 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-2026-58469 in the wild and no public exploit code.

Affected product: gnuwget wget. 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.
