Security readout for executives and security teams
Plain-English summary
CVE-2026-25117 affects pwn.college DOJO, a cybersecurity education platform. Before commit e33da14449a5abcff507e554f66e2141d6683b0a, certain workspace routes lacked sandboxing. A malicious or compromised challenge author could make JavaScript run in the site’s trusted origin, potentially performing actions as a user who views the content.
Executive priority
Prioritize remediation for public or shared DOJO environments. The business risk is user-account action abuse within the platform’s trusted origin, not confirmed system-level compromise. Treat as high priority where students, instructors, or external authors share content.
Technical view
The issue is a sandbox escape on `/workspace/*` routes in pwncollege/dojo before commit e33da14449a5abcff507e554f66e2141d6683b0a. It is categorized as CWE-20 and CWE-79. The CVSS 4.0 score is 8.3. Exploitation requires user interaction and enables arbitrary JavaScript execution in the dojo.website origin context.
Likely exposure
Exposure is limited to deployments of pwn.college DOJO running code before commit e33da14449a5abcff507e554f66e2141d6683b0a, especially where untrusted or semi-trusted challenge authors can create content viewed by users.
Exploitation context
The source bundle does not show CISA KEV listing or public active exploitation. The described attacker is a challenge author who can craft a page and needs a user to interact with or view affected content.
Researcher notes
Evidence comes from the CVE record and GitHub advisory. The advisory names a specific fixed commit but no broader version number. Do not assume other pwn.college components are affected unless vendor sources say so.
Mitigation direction
- Update DOJO to commit e33da14449a5abcff507e554f66e2141d6683b0a or later.
- Review the GitHub advisory and commit for vendor-specific remediation details.
- Restrict challenge author privileges until the affected deployment is updated.
- Review existing challenge content from untrusted authors for unexpected scripts.
Validation and detection
- Identify the running DOJO version or deployed commit hash.
- Confirm it is at or after e33da14449a5abcff507e554f66e2141d6683b0a.
- Inventory whether `/workspace/*` routes are exposed to users.
- Check whether untrusted challenge authors can publish content.
- Review access logs for unusual activity around workspace pages.
