## What is CVE-2024-7434?

CVE-2024-7434 is a high-severity unsafe deserialization vulnerability in ultrapressorg UltraPress, published on 1 Oct 2024. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

The UltraPress theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.2.2 via deserialization of untrusted input. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

Weakness: CWE-502 (Deserialization of Untrusted Data)

Affected product: ultrapressorg UltraPress. 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.
