{"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":"Livewire is a full-stack framework for Laravel that allows for dynamic UI components without leaving PHP. In livewire/livewire prior to `2.12.7` 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. If the following criteria are met, the attacker can carry out an RCE attack: 1. Filename is composed of the original file name using `$file->getClientOriginalName()`. 2. Files stored directly on your server in a public storage disk. 3. Webserver is configured to execute “.php” files. This issue has been addressed in release versions `2.12.7` and `3.5.2`. All users are advised to upgrade. There are no known workarounds for this vulnerability.","published":"2024-10-08T17:48:36.496Z","modified":"2026-07-15T01:49:12.926405309Z","cvss":null,"epss":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:12.926405309Z"}}
