## What is CVE-2023-2904?

CVE-2023-2904 is a high-severity missing authorization vulnerability in HID Global SAFE, published on 7 Jun 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The External Visitor Manager portal of HID’s SAFE versions 5.8.0 through 5.11.3 are vulnerable to manipulation within web fields in the application programmable interface (API). An attacker could log in using account credentials available through a request generated by an internal user and then manipulate the visitor-id within the web API to access the personal data of other users. There is no limit on the number of requests that can be made to the HID SAFE Web Server, so an attacker could also exploit this vulnerability to create a denial-of-service condition.

Weakness: CWE-471 (Modification of Assumed-Immutable Data (MAID))

What it is: CVE-2023-2904 is a high-severity missing authorization vulnerability in HID Global SAFE, published on 7 Jun 2023. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2023-2904 in the wild and no public exploit code.

Affected product: HID Global SAFE. 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.
