CVE-2024-42473: Authorization bypass vulnerability in OpenFGA versions 1.5.7 and 1.5.8. This vulnerability allows attackers to bypass authorization checks when the Check API is called with specific model configurations. The model must utilize but not and from expressions with a userset to be vulnerable. The immediate recommended action is to downgrade to version 1.5.6, which is backward compatible, to mitigate the risk. While the CVSS score is high, the SOCRadar Vulnerability Risk Score (SVRS) is 30, indicating a lower real-world threat level compared to the theoretical maximum. Although a patch is not yet available, OpenFGA maintainers are working on a future release to address this critical issue. The presence of "In The Wild" tag suggests potential exploitation is already occurring, underscoring the importance of taking preventative measures.
