## What is CVE-2017-8907?

CVE-2017-8907 is a high-severity missing authorization vulnerability in Atlassian Bamboo, published on 14 Jun 2017. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Atlassian Bamboo 5.x before 5.15.7 and 6.x before 6.0.1 did not correctly check if a user creating a deployment project had the edit permission and therefore the rights to do so.  An attacker who can login to Bamboo as a user without the edit permission for deployment projects is able to use this vulnerability, provided there is an existing plan with a green build, to create a deployment project and execute arbitrary code on an available Bamboo Agent.  By default a local agent is enabled; this means that code execution can occur on the system hosting Bamboo as the user running Bamboo.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2017-8907 and fix it if it is affected.

What it is: CVE-2017-8907 is a high-severity missing authorization vulnerability in Atlassian Bamboo, published on 14 Jun 2017. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-8907 in the wild and no public exploit code.

Affected product: Atlassian Bamboo. 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.
