CVE-2025-8792 is a medium-severity vulnerability affecting LitmusChaos Litmus versions up to 3.19.0. The vulnerability arises from improper enforcement of server-side security controls on the client side, allowing an attacker to bypass intended server-side restrictions by manipulating client-side mechanisms. This flaw can be exploited remotely without requiring user interaction or elevated privileges, making it accessible to unauthenticated attackers. The vulnerability's CVSS 4.0 base score is 5.3, reflecting a moderate impact primarily on the integrity of the system, with limited impact on confidentiality and availability. The attack vector is network-based with low attack complexity and no privileges or user interaction needed. The vulnerability does not involve scope or security requirements changes. Although the vendor was notified early, no response or patch has been issued, and no known exploits are currently observed in the wild. The lack of patch availability increases the risk for organizations using affected versions. LitmusChaos Litmus is a tool used for chaos engineering to test resilience in cloud-native environments, often integrated into Kubernetes clusters and CI/CD pipelines. The vulnerability could allow attackers to circumvent security controls, potentially leading to unauthorized actions or disruptions within these environments.

For European organizations, especially those leveraging cloud-native infrastructure and Kubernetes environments, this vulnerability poses a risk of unauthorized manipulation of chaos engineering experiments or related configurations. This could lead to unintended disruptions, integrity compromises, or bypass of security policies designed to safeguard production or staging environments. Organizations relying on LitmusChaos for resilience testing may face increased risk of operational instability or exposure of internal system behaviors. The medium severity indicates that while the vulnerability is not critical, exploitation could degrade trust in system integrity and impact service reliability. Given the remote exploitability and lack of required authentication, attackers could target European enterprises' development and testing environments, potentially escalating to broader operational impacts if chaos experiments are misused or manipulated maliciously.

Since no official patch or vendor response is available, European organizations should implement immediate compensating controls. These include restricting network access to LitmusChaos management interfaces using firewall rules or network segmentation to limit exposure to trusted internal users only. Employ strict authentication and authorization mechanisms around LitmusChaos deployments to prevent unauthorized access. Monitor and audit all chaos engineering activities for anomalous or unexpected experiment configurations or executions. Consider temporarily disabling or isolating LitmusChaos components in critical environments until a vendor patch is released. Additionally, review and harden Kubernetes RBAC policies to minimize privileges granted to LitmusChaos service accounts. Organizations should also stay alert for vendor updates or community patches and plan prompt deployment once available.
