## What is CVE-2024-6541?

CVE-2024-6541 is a medium-severity vulnerability in WSO2 API Manager, published on 6 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The Class Mediator fails to correctly validate or sanitize `messageContext` properties when they are used to populate dynamic values. This allows authenticated users to potentially access or modify data across different system invocations that should be isolated.

This weakness can lead to the disclosure of sensitive information belonging to other users or the unintended modification of system data by authenticated users. The exact impact depends on how `messageContext` properties are utilized within the affected WSO2 products.

Weakness: CWE-20 (Improper Input Validation)

Check this codebase for CVE-2024-6541 and fix it if it is affected.

What it is: CVE-2024-6541 is a medium-severity vulnerability in WSO2 API Manager, published on 6 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-6541 in the wild and no public exploit code.

Affected product: WSO2 API 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.
5. If nothing in the project is affected, say so and change nothing.
