GHSA-F2PH-CMG5-WXC8
Vulnerability from github – Published: 2026-10-21 17:23 – Updated: 2026-10-21 17:23Summary: A malicious website may be able to cause unauthorized file changes in a developer’s project while an affected Storybook development server is running. Under additional conditions, a changed file could be executed by a local runtime with the developer’s privileges. We are not aware of exploitation in the wild.
Who is impacted?
You are impacted if you run a Storybook dev server in the affected versions.
You are not impacted if:
- You run a dev server that you never open in a web browser (e.g. headless automation, MCP clients)
- You run or visit a built version of Storybook
Recent versions of Chrome and Firefox may ask for permission before a website can connect to a localhost service. This reduces the risk, but does not remove it. Do not grant this permission to websites you don’t trust.
Recommended actions
Upgrade Storybook
Storybook has released patched versions of all affected major Storybook versions that fix all the vulnerabilities necessary for the worst-case scenario above to occur.
Upgrade to a patched version listed below before running storybook dev again. If you cannot upgrade immediately, do not run an affected Storybook dev server until you can apply the fix.
- 11.0.0-alpha.6
- 10.6.2
- 9.1.21
- 8.6.19
Review potentially breaking changes
Due to the exceptional nature of the reported vulnerabilities, the Storybook team has decided to change the default behavior of Storybook, including versions 8 and 9, for several network-related features that are not essential to most Storybook users' workflow. If your team relies on the affected features, we've added feature flags that can disable specific security updates to support your existing workflows.
Please carefully read the introduced flags and the consequences of using them.
Iframe embedding over the network is disabled by default
Storybook no longer allows the manager or preview to be embedded as an iframe on a website with a different host name. Built versions of Storybook are unaffected and can be freely embedded.
If you rely on embedding a Storybook dev server through a separate web app, run that separate app on localhost. You may also use the security.insecureRemoteIframeEmbed feature flag to re-enable iframe embedding from any origin.
The preview iframe rejects messages sent by an unknown host
Both the Storybook preview and manager now restrict the origin of iframes and parent windows that they can send messages to and receive messages from using the postMessage API.
By default, Storybook in dev mode only accepts communication with its own origin and other localhost services. Built Storybooks continue to accept communication from unknown origins.
A Storybook addon or integration could hypothetically rely on postMessage to update a live story's args. If you do that, reach out to the Storybook team to explore safer alternatives.
Storybook composition also relies on postMessage, so a composed Storybook on a different origin now fails to load unless it has been built. The security.insecureIframeMessaging feature flag disables this protection, but we recommend you build composed Storybooks instead.
The highlight event signature has changed
Storybook’s own accessibility addon uses the highlight event to inject highlights into the preview, which a user can click. Clicking the highlight opens a menu with a link to a documentation page.
The API for that event was too permissive and could be used to trigger arbitrary events, including events processed by the user’s dev server. We reworked the API to prevent abuse. Besides the accessibility addon, Chromatic's Visual Tests addon uses this API to link to documentation from highlighted ignored elements. Update the Visual Tests addon to version 5.5.1 or later to keep that link working. Because no other addons use this API as far as we know, we have not added a feature flag to restore the old API.
Disclosure timeline
On September 30th, the Storybook team received a responsible disclosure showing how a malicious website can embed a Storybook dev server's preview iframe and send events to the dev server on the developer's machine.
They combined this information with findings from an ongoing security audit to come up with a worst-case-scenario exploitation of the disclosed vulnerability, and the ones we independently discovered. They then worked to address all layers necessary for this worst-case scenario to happen. We have not received evidence of exploitation in real Storybook projects. The attack outlined in this advisory relies on correctly exploiting a sequence of many vulnerabilities, some of which were never disclosed to the Storybook team.
Worst-case attack scenario
An attacker-controlled website can interact with the preview of a running Storybook dev server. With user interaction, it may cause the dev server to make unauthorized changes to story files. If a malicious file is subsequently executed by a local runtime, the attack could lead to arbitrary code execution with the developer’s permissions.

"details": "**Summary:** A malicious website may be able to cause unauthorized file changes in a developer\u2019s project while an affected Storybook development server is running. Under additional conditions, a changed file could be executed by a local runtime with the developer\u2019s privileges. We are not aware of exploitation in the wild.\n\n## Who is impacted?\n\nYou are impacted if you run a Storybook dev server in the affected versions.\n\nYou are not impacted if:\n\n- You run a dev server that you never open in a web browser (e.g. headless automation, MCP clients)\n- You run or visit a built version of Storybook\n\nRecent versions of Chrome and Firefox may ask for permission before a website can connect to a `localhost` service. This reduces the risk, but does not remove it. Do not grant this permission to websites you don\u2019t trust.\n\n## Recommended actions\n\n### Upgrade Storybook\n\nStorybook has released patched versions of all affected major Storybook versions that fix all the vulnerabilities necessary for the worst-case scenario above to occur. \n\nUpgrade to a patched version listed below before running `storybook dev` again. If you cannot upgrade immediately, do not run an affected Storybook dev server until you can apply the fix.\n\n- 11.0.0-alpha.6\n- 10.6.2\n- 9.1.21\n- 8.6.19\n\n### Review potentially breaking changes\n\nDue to the exceptional nature of the reported vulnerabilities, the Storybook team has decided to change the default behavior of Storybook, including versions 8 and 9, for several network-related features that are not essential to most Storybook users\u0027 workflow. If your team relies on the affected features, we\u0027ve added feature flags that can disable specific security updates to support your existing workflows.\n\nPlease carefully read the introduced flags and the consequences of using them.\n\n#### Iframe embedding over the network is disabled by default\n\nStorybook no longer allows the manager or preview to be embedded as an iframe on a website with a different host name. Built versions of Storybook are unaffected and can be freely embedded.\n\nIf you rely on embedding a Storybook dev server through a separate web app, run that separate app on `localhost`. You may also use the `security.insecureRemoteIframeEmbed` feature flag to re-enable iframe embedding from any origin.\n\n#### The preview iframe rejects messages sent by an unknown host\n\nBoth the Storybook preview and manager now restrict the origin of iframes and parent windows that they can send messages to and receive messages from using the `postMessage` API.\n\nBy default, Storybook in dev mode only accepts communication with its own origin and other `localhost` services. Built Storybooks continue to accept communication from unknown origins.\n\nA Storybook addon or integration could hypothetically rely on `postMessage` to update a live story\u0027s args. If you do that, reach out to the Storybook team to explore safer alternatives.\n\nStorybook composition also relies on `postMessage`, so a composed Storybook on a different origin now fails to load unless it has been built. The `security.insecureIframeMessaging` feature flag disables this protection, but we recommend you build composed Storybooks instead.\n\n#### The `highlight` event signature has changed\n\nStorybook\u2019s own accessibility addon uses the `highlight` event to inject highlights into the preview, which a user can click. Clicking the highlight opens a menu with a link to a documentation page.\n\nThe API for that event was too permissive and could be used to trigger arbitrary events, including events processed by the user\u2019s dev server. We reworked the API to prevent abuse. Besides the accessibility addon, Chromatic\u0027s Visual Tests addon uses this API to link to documentation from highlighted ignored elements. Update the Visual Tests addon to version 5.5.1 or later to keep that link working. Because no other addons use this API as far as we know, we have not added a feature flag to restore the old API.\n\n## Disclosure timeline\n\nOn September 30th, the Storybook team received a responsible disclosure showing how a malicious website can embed a Storybook dev server\u0027s preview iframe and send events to the dev server on the developer\u0027s machine.\n\nThey combined this information with findings from an ongoing security audit to come up with a worst-case-scenario exploitation of the disclosed vulnerability, and the ones we independently discovered. They then worked to address all layers necessary for this worst-case scenario to happen. We have not received evidence of exploitation in real Storybook projects. The attack outlined in this advisory relies on correctly exploiting a sequence of many vulnerabilities, some of which were never disclosed to the Storybook team.\n\n### Worst-case attack scenario\n\nAn attacker-controlled website can interact with the preview of a running Storybook dev server. With user interaction, it may cause the dev server to make unauthorized changes to story files. If a malicious file is subsequently executed by a local runtime, the attack could lead to arbitrary code execution with the developer\u2019s permissions.",

Mitigation
Strategy: Refactoring
Refactor your program so that you do not have to dynamically generate code.
Mitigation
- Run your code in a "jail" or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which code can be executed by your product.
- Examples include the Unix chroot jail and AppArmor. In general, managed code may provide some protection.
- This may not be a feasible solution, and it only limits the impact to the operating system; the rest of your application may still be subject to compromise.
- Be careful to avoid CWE-243 and other weaknesses related to jails.
Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of code injection, use stringent allowlists that limit which constructs are allowed. If you are dynamically constructing code that invokes a function, then verifying that the input is alphanumeric might be insufficient. An attacker might still be able to reference a dangerous function that you did not intend to allow, such as system(), exec(), or exit().
Mitigation
Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
Mitigation MIT-32
Strategy: Compilation or Build Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation MIT-32
Strategy: Environment Hardening
Run the code in an environment that performs automatic taint propagation and prevents any command execution that uses tainted variables, such as Perl's "-T" switch. This will force the program to perform validation steps that remove the taint, although you must be careful to correctly validate your inputs so that you do not accidentally mark dangerous inputs as untainted (see CWE-183 and CWE-184).
Mitigation
For Python programs, it is frequently encouraged to use the ast.literal_eval() function instead of eval, since it is intentionally designed to avoid executing code. However, an adversary could still cause excessive memory or stack consumption via deeply nested structures [REF-1372], so the python documentation discourages use of ast.literal_eval() on untrusted data [REF-1373].
CAPEC-242: Code Injection
An adversary exploits a weakness in input validation on the target to inject new code into that which is currently executing. This differs from code inclusion in that code inclusion involves the addition or replacement of a reference to a code file, which is subsequently loaded by the target and used as part of the code of some application.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-77: Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
