## What is CVE-2011-10033?

CVE-2011-10033 is a critical code injection vulnerability in is-human WordPress Plugin, published on 15 Oct 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The WordPress plugin is-human <= v1.4.2 contains an eval injection vulnerability in /is-human/engine.php that can be triggered via the 'type' parameter when the 'action' parameter is set to 'log-reset'. The root cause is unsafe use of eval() on user-controlled input, which can lead to execution of attacker-supplied PHP and OS commands. This may result in arbitrary code execution as the webserver user, site compromise, or data exfiltration. The is-human plugin was made defunct in June 2008 and is no longer available for download. This vulnerability was exploited in the wild in March 2012.

Weakness: CWE-95 (Improper Neutralization of Directives in Dynamically Evaluated Code)

Affected product: is-human WordPress Plugin. 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.
