## What is CVE-2023-40619?

CVE-2023-40619 is a critical unsafe deserialization vulnerability in n/a, published on 20 Sep 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

phpPgAdmin 7.14.4 and earlier is vulnerable to deserialization of untrusted data which may lead to remote code execution because user-controlled data is directly passed to the PHP 'unserialize()' function in multiple places. An example is the functionality to manage tables in 'tables.php' where the 'ma[]' POST parameter is deserialized.

Weakness: CWE-502 (Deserialization of Untrusted Data)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2023-40619 and fix it if it is affected.

What it is: CVE-2023-40619 is a critical unsafe deserialization vulnerability in n/a, published on 20 Sep 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2023-40619 in the wild and no public exploit code.

Affected product: n/a. 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.
