CVE intelligence and bounded remediation
CVE-2023-28109 — Play With Docker is a browser-based Docker playground
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.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
