CVE-2026-54321: CWE-613: Insufficient Session Expiration in daytonaio daytona
Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows. From 0.101.0 until 0.184.0, sandbox previews that were switched from public to private could remain reachable without authentication for a short period after the change, due to a cached visibility state that was not invalidated when the sandbox's visibility changed. This vulnerability is fixed in 0.184.0.
AI Analysis
Technical Summary
The vulnerability CVE-2026-54321 in daytonaio daytona (versions >=0.101.0 <0.184.0) is caused by insufficient session expiration related to cached visibility state. When sandbox previews are changed from public to private, the cached state was not invalidated immediately, allowing these previews to remain reachable without authentication for a short time. This issue is classified under CWE-613 (Insufficient Session Expiration) and CWE-863 (Incorrect Authorization). The vulnerability is fixed in version 0.184.0.
Potential Impact
Unauthorized users could access sandbox previews that were intended to be private shortly after their visibility was changed from public to private. This exposure could lead to confidentiality breaches of sandbox content during the window before the cache invalidation occurs. The CVSS score of 7 indicates a high impact primarily on confidentiality, with limited integrity and availability impact.
Mitigation Recommendations
Upgrade daytona to version 0.184.0 or later where the vulnerability is fixed. Since the vendor advisory indicates the issue is resolved in 0.184.0, applying this official fix is the recommended remediation. No additional temporary mitigations are specified.
