{"id":"CVE-2024-47823","aliases":["GHSA-f3cx-396f-7jqp"],"url":"https://o3.security/vulnerability/CVE-2024-47823","summary":"Livewire Remote Code Execution (RCE) on File Uploads","details":"In livewire/livewire prior to `v2.12.7` and `v3.5.2`, the file extension of an uploaded file is guessed based on the MIME type. As a result, the actual file extension from the file name is not validated. An attacker can therefore bypass the validation by uploading a file with a valid MIME type (e.g., `image/png`) and a “.php” file extension.\nIf the following criteria are met, the attacker can carry out an RCE attack:\n\n- Filename is composed of the original file name using `$file->getClientOriginalName()`\n- Files stored directly on your server in a public storage disk\n- Webserver is configured to execute “.php” files\n\n### PoC\nIn the following scenario, an attacker could upload a file called `shell.php` with an `image/png` MIME type and execute it on the remote server.\n```php\nclass SomeComponent extends Component\n{\n    use WithFileUploads;\n\n    #[Validate('image|extensions:png')]\n    public $file;\n\n    public function save()\n    {\n        $this->validate();\n\n        $this->file->storeAs(\n            path: 'images',\n            name: $this->file->getClientOriginalName(),\n            options: ['disk' => 'public'],\n        );\n    }\n}\n```\n\n","published":"2024-10-08T17:48:36.496Z","modified":"2026-08-12T03:51:10.713378220Z","cvss":null,"epss":{"score":0.00846,"percentile":0.56343,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"Packagist","name":"livewire/livewire","fixedVersion":"3.5.2"},{"ecosystem":"Packagist","name":"livewire/livewire","fixedVersion":"2.12.7"}],"fix":{"url":"https://github.com/livewire/livewire/commit/70503b79f5db75a1eac9bf55826038a6ee5a16d5","label":"livewire/livewire@70503b7"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/47xxx/CVE-2024-47823.json"},{"type":"ADVISORY","url":"https://github.com/livewire/livewire/security/advisories/GHSA-f3cx-396f-7jqp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-47823"},{"type":"FIX","url":"https://github.com/livewire/livewire/commit/70503b79f5db75a1eac9bf55826038a6ee5a16d5"},{"type":"FIX","url":"https://github.com/livewire/livewire/commit/cd168c6212ea13d13b82b3132485741f82d9fad9"},{"type":"FIX","url":"https://github.com/livewire/livewire/pull/8624"},{"type":"PACKAGE","url":"https://github.com/livewire/livewire"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:10.713378220Z"}}
