## What is CVE-2023-38508?

CVE-2023-38508 is a medium-severity missing authorization vulnerability in Enalean Tuleap, published on 24 Aug 2023. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Tuleap is an open source suite to improve management of software developments and collaboration. In Tuleap Community Edition prior to version 14.11.99.28 and Tuleap Enterprise Edition prior to versions 14.10-6 and 14.11-3, the preview of an artifact link with a type does not respect the project, tracker and artifact level permissions. The issue occurs on the artifact view (not reproducible on the artifact modal). Users might get access to information they should not have access to. Only the title, status, assigned to and last update date fields as defined by the semantics are impacted. If those fields have strict permissions (e.g. the title is only visible to a specific user group) those permissions are still enforced. Tuleap Community Edition 14.11.99.28, Tuleap Enterprise Edition 14.10-6, and Tuleap Enterprise Edition 14.11-3 contain a fix for this issue.

Weakness: CWE-862 (Missing Authorization), CWE-285 (Improper Authorization)

Check this codebase for CVE-2023-38508 and fix it if it is affected.

What it is: CVE-2023-38508 is a medium-severity missing authorization vulnerability in Enalean Tuleap, published on 24 Aug 2023. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-38508 exists.

Affected product: Enalean Tuleap. 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.
