Description

This security bulletin contains information about 1 vulnerability.


1) Incorrect authorization (CVE-ID: N/A)

CWE-ID: CWE-863 - Incorrect Authorization

CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote user to bypass authorization and modify or delete records without permission.

The vulnerability exists due to incorrect authorization in Livewire's #[Authorize] handling when resolving model parameters inconsistently with positional invocation or executing #[Json] methods before authorization checks. A remote user can submit reordered integer parameter keys such as {"1": 2, "0": 1} to actions or event listeners through __dispatch, or invoke methods combining #[Json] and #[Authorize], to perform unauthorized database writes or deletions.
