## What is CVE-2024-52531?

CVE-2024-52531 is a medium-severity memory corruption vulnerability in GNOME libsoup, published on 11 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

GNOME libsoup before 3.6.1 allows a buffer overflow in applications that perform conversion to UTF-8 in soup_header_parse_param_list_strict. There is a plausible way to reach this remotely via soup_message_headers_get_content_type (e.g., an application may want to retrieve the content type of a request or response).

Weakness: CWE-787 (Out-of-bounds Write)

Check this codebase for CVE-2024-52531 and fix it if it is affected.

What it is: CVE-2024-52531 is a medium-severity memory corruption vulnerability in GNOME libsoup, published on 11 Nov 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-52531 exists.

Affected product: GNOME libsoup. 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.
