Summary

Summary Daytona's organization role update and delete endpoints authorized the caller as an owner of the organization named in the request path, but resolved and mutated the target role by its identifier alone, without verifying the role belonged to that organization. An authenticated user who owns any organization (organizations are self-service) could therefore modify the permissions of, or delete, a role belonging to a different organization, given that role's identifier. Impact This is a cross-tenant broken access control (IDOR) issue affecting multi-tenant deployments, including the managed Daytona platform. Using a target role's identifier, an attacker with owner rights over their own organization could: Overwrite the target role's name and permission set, escalating or stripping privileges for every member and API key in the victim organization that holds that role. Delete the target role, removing the associated permissions from its holders. Observe the victim role's current permission set returned in the update response (limited information disclosure). Exploitation requires knowledge of the target role's identifier, which is not enumerable across organizations and is not exposed to non-members through the API. Affected versions All versions up to and including 0.184.0. Patches Fixed in 0.185.0. The role update, delete, and role-assignment lookups are now scoped to the caller's organization, so a role belonging to another organization resolves to "not found" before any read or mutation. The managed Daytona platform was updated on release of 0.185.0. Workarounds None. Upgrade to 0.185.0. Single-organization self-hosted deployments are not exploitable, as the issue requires a second organization to target. Credit Reported by @vnth4nhnt.

Impact

What is missing authorization?

The application does not perform an authorization check before performing a sensitive operation. Typical impact: unauthorized access to restricted functionality or data.

Severity and exposure

CVE-2026-54322 has a CVSS score of 7.7 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.

A fixed version is available (0.185.0). Upgrading removes the vulnerable code path.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

Kodem's runtime-powered SCA identifies whether CVE-2026-54322 is reachable in your applications. Explore open-source security for your team.

Frequently asked questions about CVE-2026-54322

What is CVE-2026-54322?

CVE-2026-54322 is a high-severity missing authorization vulnerability in github.com/daytonaio/daytona (go), affecting versions <= 0.184.0. It is fixed in 0.185.0. The application does not perform an authorization check before performing a sensitive operation.

How severe is CVE-2026-54322?

CVE-2026-54322 has a CVSS score of 7.7 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.

Which versions of github.com/daytonaio/daytona are affected by CVE-2026-54322?

github.com/daytonaio/daytona (go) versions <= 0.184.0 is affected.

Is there a fix for CVE-2026-54322?

Yes. CVE-2026-54322 is fixed in 0.185.0. Upgrade to this version or later.

Is CVE-2026-54322 exploitable, and should I be worried?

Whether CVE-2026-54322 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2026-54322 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix CVE-2026-54322?

Upgrade github.com/daytonaio/daytona to 0.185.0 or later.
