GHSA-c42h-56wx-h85q:
PHP vulnerability analysis and mitigation
Overview
The laravel-auth0 SDK (versions 7.0.0-BETA1 to 7.2.1) contains a critical vulnerability (GHSA-c42h-56wx-h85q) related to insecure deserialization of cookie data. The vulnerability was discovered by Andreas Forsblom and disclosed on June 3, 2025. The issue affects applications using the laravel-auth0 SDK that relies on Auth0-PHP SDK versions between 8.0.0-BETA3 to 8.3.0 (GitHub Advisory).
Technical details
The vulnerability stems from insecure deserialization of cookie data in the SDK. Since the SDKs process cookie content without prior authentication, attackers can exploit this by sending specially crafted cookies containing malicious serialized data. The vulnerability has been assigned a Critical severity rating with a CVSS v4.0 score of 9.3, with the vector string CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:H/SI:H/SA:H. The vulnerability is classified under CWE-502 (Deserialization of Untrusted Data) (GitHub Advisory, NVD).
Impact
The vulnerability has significant impact potential, particularly on system integrity and subsequent system components. According to the CVSS metrics, while there is no direct impact on confidentiality of the vulnerable system, it can lead to high integrity impacts. Furthermore, the vulnerability can cause high impacts on the confidentiality, integrity, and availability of subsequent systems (GitHub Advisory).
Mitigation and workarounds
The recommended mitigation is to upgrade Auth0/laravel-auth0 to version 7.2.2 or later (specifically v7.17.0). This patch addresses the insecure deserialization vulnerability (GitHub Advisory).
