Prior to version 4.24, the Filer JWT validation mechanism used a raw prefix match, allowing scoped tokens to access sibling directories sharing similar name prefixes.\n\n## TL;DR\nSeaweedFS Filer prior to 4.24 uses raw prefix matching on raw path strings during JWT validation, allowing scoped tokens to authorize unauthorized access to sibling directories (e.g., /tenant1 matching /tenant1234).\n\n## Technical Details\n\n- **CWE ID**: CWE-863\n- **Attack Vector**: Network (AV:N)\n- **CVSS v3.1 Score**: 8.1 (High)\n- **EPSS Score**: 0.00238 (0.24%)\n- **Exploit Status**: none\n- **KEV Status**: Not Listed\n\n## Affected Systems\n\n- SeaweedFS Filer\n- Wolfi\n- Chainguard\n- **SeaweedFS**: < 4.24 (Fixed in: `4.24`)\n\n## Mitigation\n\n- Upgrade SeaweedFS to version 4.24 or later to enforce component-aware path authorization.\n- Refactor tenant namespace directories to prevent overlapping suffix names.\n- Enforce trailing slashes on all scoped JWT AllowedPrefixes claims.\n\n**Remediation Steps:**\n1.
