## What is CVE-2024-10242?

CVE-2024-10242 is a medium-severity cross-site scripting vulnerability in Wso2 Api Manager, published on 16 Apr 2026. 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

The authentication endpoint fails to adequately validate user-supplied input before reflecting it back in the response. This allows an attacker to inject malicious script payloads into the input parameters, which are then executed by the victim's browser.

Successful exploitation can enable an attacker to redirect the user's browser to a malicious website, modify the UI of the web page, or retrieve information from the browser. However, the impact is limited as session-related sensitive cookies are protected by the httpOnly flag, preventing session hijacking.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

Check this codebase for CVE-2024-10242 and fix it if it is affected.

What it is: CVE-2024-10242 is a medium-severity cross-site scripting vulnerability in Wso2 Api Manager, published on 16 Apr 2026. 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-2024-10242 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.
