## What is CVE-2024-23745?

CVE-2024-23745 is a critical code injection vulnerability in n/a, published on 31 Jan 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

In Notion Web Clipper 1.0.3(7), a .nib file is susceptible to the Dirty NIB attack. NIB files can be manipulated to execute arbitrary commands. Additionally, even if a NIB file is modified within an application, Gatekeeper may still permit the execution of the application, enabling the execution of arbitrary commands within the application's context. NOTE: the vendor's perspective is that this is simply an instance of CVE-2022-48505, cannot properly be categorized as a product-level vulnerability, and cannot have a product-level fix because it is about incorrect caching of file signatures on macOS.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)

Check this codebase for CVE-2024-23745 and fix it if it is affected.

What it is: CVE-2024-23745 is a critical code injection vulnerability in n/a, published on 31 Jan 2024. 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-2024-23745 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.
