By manipulating URL parameters, an attacker can hijack the real-time communications channel, enabling them to capture user state and control parameters from active sessions.\n\n## TL;DR\nUnauthenticated remote attackers can hijack active phoenix_storybook sessions by supplying a victim's PubSub topic via URL parameters, leading to potential cross-session state exposure.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-639\n- **Attack Vector**: Network\n- **CVSS Score**: 2.3 (Low)\n- **EPSS Score**: 0.00054\n- **Exploit Status**: No active public exploits\n- **KEV Status**: Not listed\n\n## Affected Systems\n\n- phoenix_storybook package for Elixir\n- **phoenix_storybook**: &gt;= 0.4.0, &lt; 1.1.0 (Fixed in: `1.1.0`)\n\n## Mitigation\n\n- Upgrade phoenix_storybook to version 1.1.0 or higher.\n- Ensure application endpoint configuration uses a secure, non-default secret_key_base.\n- Manually verify playground topic strings using Phoenix.Token in custom storybook setups.\n\n**Remediation Steps:**\n1. Inspect mix.exs to determine the current phoenix_storybook version.\n2. Update the dependency to `{:phoenix_storybook, \"~&gt; 1.1.0\"}`.\n3. Run `mix deps.get` to download and compile the updated package.\n4. Verify deployment by inspecting URL parameters within the storybook playground iframe (should use 'playground_token' instead of 'topic').\n\n## References\n\n- [https://github.com/phenixdigital/phoenix_storybook/security/advisories/GHSA-mrhx-6pw9-q5fh](https://github.com/phenixdigital/phoenix_storybook/security/advisories/GHSA-mrhx-6pw9-q5fh)\n- [https://github.com/phenixdigital/phoenix_storybook/commit/6ee03f1c738d4436dde1b066cf65c80663d489f5](https://github.com/phenixdigital/phoenix_storybook/commit/6ee03f1c738d4436dde1b066cf65c80663d489f5)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-47068) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-06-09T22:51:34.000000Z"}]}
