## What is CVE-2024-10318?

CVE-2024-10318 is a medium-severity authentication bypass vulnerability in F5 NGINX API Connectivity Manager, published on 6 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

A session fixation issue was discovered in the NGINX OpenID Connect reference implementation, where a nonce was not checked at login time. This flaw allows an attacker to fix a victim's session to an attacker-controlled account. As a result, although the attacker cannot log in as the victim, they can force the session to associate it with the attacker-controlled account, leading to potential misuse of the victim's session.

Weakness: CWE-384 (Session Fixation)

What it is: CVE-2024-10318 is a medium-severity authentication bypass vulnerability in F5 NGINX API Connectivity Manager, published on 6 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-10318 in the wild and no public exploit code.

Affected product: F5 NGINX API Connectivity Manager. 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.
