CVE-2026-24816 is a vulnerability classified under CWE-835, indicating a loop with an unreachable exit condition, commonly known as an infinite loop. This flaw exists in the datavane tis product, specifically within the ChangeDomainAction.Java source file in the tis-console module. The vulnerability affects all versions prior to 4.3.0. The infinite loop occurs due to improper loop control logic, causing the program to enter a state where it cannot exit the loop under certain conditions. This results in the consumption of CPU resources indefinitely, leading to denial of service (DoS) conditions. The CVSS 4.0 base score is 10, reflecting a critical severity level. The vector indicates that the attack can be performed remotely (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:L). The scope is changed (S:P), and the attack requires authentication (AU:Y), which slightly reduces the attack surface but does not diminish the critical impact. No patches or exploits are currently publicly available, but the vulnerability is published and should be addressed promptly. The infinite loop can cause system unavailability, potentially disrupting services relying on datavane tis, which is used for data integration and processing tasks.

For European organizations, the impact of CVE-2026-24816 can be severe, especially for those relying on datavane tis for critical data processing and integration workflows. The infinite loop can lead to denial of service, causing system outages and operational disruptions. This may affect business continuity, data availability, and could indirectly impact confidentiality and integrity if systems become unstable or require emergency interventions. Organizations in sectors such as finance, healthcare, manufacturing, and government services that use datavane tis could face significant operational risks. The resource exhaustion caused by the infinite loop could also lead to cascading failures in interconnected systems. Additionally, the requirement for authentication to exploit the vulnerability means insider threats or compromised credentials could be leveraged to trigger the attack, increasing risk in environments with weak access controls. The absence of known exploits in the wild provides a window for proactive mitigation, but the critical severity demands urgent attention.

1. Upgrade datavane tis to version 4.3.0 or later, where this vulnerability is fixed. 2. Implement strict access controls and multi-factor authentication to reduce the risk of credential compromise, since exploitation requires authentication. 3. Deploy runtime monitoring and anomaly detection tools to identify unusual CPU usage or process behavior indicative of infinite loops. 4. Use network segmentation and firewall rules to limit access to the tis-console module, reducing exposure to potential attackers. 5. Conduct regular security audits and code reviews focusing on loop constructs and exit conditions in custom or extended modules. 6. Prepare incident response plans specifically addressing denial of service scenarios caused by resource exhaustion. 7. Engage with datavane support or vendor security teams to receive timely updates and patches. 8. Consider implementing resource limits (e.g., CPU quotas, process timeouts) at the operating system or container orchestration level to mitigate impact if exploitation occurs.
