## What is CVE-2020-36192?

CVE-2020-36192 is a medium-severity missing authorization vulnerability in n/a, published on 18 Jan 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in the Source Integration plugin before 2.4.1 for MantisBT. An attacker can gain access to the Summary field of private Issues (either marked as Private, or part of a private Project), if they are attached to an existing Changeset. The information is visible on the view.php page, as well as on the list.php page (a pop-up on the Affected Issues id hyperlink). Additionally, if the attacker has "Update threshold" in the plugin's configuration (set to the "updater" access level by default), then they can link any Issue to a Changeset by entering the Issue's Id, even if they do not have access to it.

What it is: CVE-2020-36192 is a medium-severity missing authorization vulnerability in n/a, published on 18 Jan 2021. 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-2020-36192 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.
