CVE-2023-28109
MEDIUMPlay With Docker vulnerable to Authorization Bypass Through User-Controlled Key
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Play With Docker is a browser-based Docker playground. Versions 0.0.2 and prior are vulnerable to domain hijacking.
Because CORS configuration was not correct, an attacker could use play-with-docker.com as an example and set the origin header in an http request as evil-play-with-docker.com. The domain would echo in response header, which successfully bypassed the CORS policy and retrieved basic user information. This issue has been fixed in commit ed82247c9ab7990ad76ec2bf1498c2b2830b6f1a. There are no known workarounds.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/play-with-docker/play-with-docker. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of github.com/play-with-docker/play-with-docker has shipped for CVE-2023-28109 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2023-28109 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2023-28109. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-28109 in your dependencies?
O3 detects CVE-2023-28109 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
