{"schema":"threatline.record/2","record":{"id":"GHSA-mhf7-xp6r-6qrc","aliases":["GHSA-mhf7-xp6r-6qrc"],"summary":"Livewire: Authorization bypass in #[Authorize] via reordered parameter keys and #[Json] execution order","details":"### Impact\n\nThree issues allowed actions protected by the `#[Authorize]` attribute to run against records the current user is not authorized for:\n\n1. **Out-of-order parameter keys on actions.** `#[Authorize]` resolved a model parameter by its array key, while the action itself received parameters positionally. A request sending params as an object with reordered integer keys (e.g. `{\"1\": 2, \"0\": 1}`) could pass authorization with a record the user owns while the action received a different record. With `#[Authorize('delete', 'comment')]` on `deleteComment(Comment $comment)`, a user could delete another user's comment.\n2. **The same issue on event listeners.** Methods using both `#[On]` and `#[Authorize]` with a model parameter were affected in the same way through the `__dispatch` call.\n3. **`#[Json]` methods ran before authorization.** When a method had both `#[Json]` and `#[Authorize]`, the method body executed before the authorization check. The response was still a 403, but any side effects (such as database writes) had already happened.\n\nOnly applications using the `#[Authorize]` attribute are affected: on methods that take model parameters (issues 1 and 2), or on `#[Json]` methods (issue 3). Authorization performed inside the method (e.g. `$this->authorize(...)`) is not affected. Livewire 3.x is not affected.\n\n### Patches\n\nFixed in **v4.4.8**. Call and event parameters must now be a list or use named (string) keys, otherwise the request is rejected, and `#[Json]` methods are authorized before they run.\n\n### Workarounds\n\nUpgrade to v4.4.8. If you can't upgrade right away, call `$this->authorize(...)` inside affected methods instead of relying on the `#[Authorize]` attribute.\n\n### Credits\n\nReported by Yousef Aman ([@yousef-aman](https://github.com/yousef-aman)).","categories":["Libraries & packages"],"product":"livewire/livewire","vendor":"","ecosystem":"composer","affected_ranges":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-mhf7-xp6r-6qrc","source_modified_at":"2026-10-23T20:51:30Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"ecosystem":"composer","name":"livewire/livewire"},"range":">= 4.3.0, < 4.4.8"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-mhf7-xp6r-6qrc","source_modified_at":"2026-10-23T21:00:04.354707498Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"name":"livewire/livewire","ecosystem":"Packagist","purl":"pkg:composer/livewire/livewire"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.3.0"},{"fixed":"4.4.8"}]}],"versions":["v4.3.0","v4.3.1","v4.3.2","v4.3.3","v4.3.4","v4.3.5","v4.4.0","v4.4.1","v4.4.2","v4.4.3","v4.4.4","v4.4.5","v4.4.6","v4.4.7"]}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/advisories/GHSA-mhf7-xp6r-6qrc","source_modified_at":"2026-10-23T20:51:30Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"ecosystem":"composer","name":"livewire/livewire"},"version":"4.4.8"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-mhf7-xp6r-6qrc","source_modified_at":"2026-10-23T21:00:04.354707498Z","fetched_at":"2026-10-23T21:10:45.942435Z","package":{"name":"livewire/livewire","ecosystem":"Packagist","purl":"pkg:composer/livewire/livewire"},"version":"4.4.8"}],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T20:51:30Z","modified_at":"2026-10-23T21:00:04.354707498Z","provenance":[{"source":"GitHub Advisory Database","url":"https://github.com/advisories/GHSA-mhf7-xp6r-6qrc","fetched_at":"2026-10-23T21:10:45.942435Z","source_modified_at":"2026-10-23T20:51:30Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-mhf7-xp6r-6qrc","fetched_at":"2026-10-23T21:10:45.942435Z","source_modified_at":"2026-10-23T21:00:04.354707498Z"}],"sources":["GitHub Advisory Database","OSV"],"references":[{"url":"https://github.com/livewire/livewire/security/advisories/GHSA-mhf7-xp6r-6qrc","source":"GitHub Advisory Database"},{"url":"https://github.com/livewire/livewire/commit/822a4fa9b1e1123691133a2e2eb379a3dab11191","source":"GitHub Advisory Database"},{"url":"https://github.com/livewire/livewire/releases/tag/v4.4.8","source":"GitHub Advisory Database"},{"url":"https://github.com/advisories/GHSA-mhf7-xp6r-6qrc","source":"GitHub Advisory Database"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-23T21:00:04.354707498Z","content_hash":"6feccb7957c137789c9752723e67f913f699f5ccd8e5ddcbb09e1e7ded3b7788"}}
