CVE-2026-75844 ArcadeData CVE debrief

Who should care

Users of ArcadeDB versions before 26.8.1, especially those with authenticated access to the IMPORT DATABASE command, should be aware of this vulnerability and take steps to mitigate it. Operators, platform administrators, vulnerability management teams, and security teams should review the vulnerability details and assess their exposure to this vulnerability. They should also verify whether affected product deployments exist in their managed environments and assign an owner for follow-up. Additionally, they should implement compensating controls for exposed systems while remediation is scheduled and verified, and track exceptions and retest remediated assets to close the item only after evidence is documented. Furthermore, they should check relevant monitoring, detection, and logs for exposed assets that need extra review. Finally, they should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. This vulnerability has a high CVSS score of 7.1, indicating a high severity level. Therefore, it is crucial for affected users to take immediate action to mitigate the vulnerability and prevent potential attacks. The CVE record was published on 2026-08-18T12:19:34.890Z and has not been modified since then, which may impact the timeliness of the information provided. Users should also consider the limitations of the evidence provided and the potential for undisclosed or unconfirmed details about the vulnerability. In light of these factors, users should exercise caution and consider multiple sources when assessing their risk and developing mitigation strategies. To further address this vulnerability, users may need to implement additional security measures to monitor and limit connections to sensitive endpoints, as well as restrict access to the IMPORT DATABASE command for authenticated users. By taking these steps, users can help protect their systems from potential attacks and minimize the risk associated with this vulnerability. In addition to these measures, users should also consider reviewing compensting

Technical summary

The IMPORT DATABASE command in ArcadeDB versions before 26.8.1 is vulnerable to server-side request forgery. The security validator checks hostnames but the subsequent connection re-resolves the raw URL, allowing attackers to bypass the validator using DNS rebinding or HTTP redirects. This vulnerability allows authenticated attackers to access sensitive endpoints or read local files on default installations.

Defensive priority

Authenticated attackers can bypass security validators to access sensitive endpoints or read local files.

Recommended defensive actions

• Inventory and verify ArcadeDB installations for version 26.8.1 or later.
• Restrict access to IMPORT DATABASE command for authenticated users.
• Implement additional security measures to monitor and limit connections to sensitive endpoints.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.

Evidence notes

The vulnerability exists in ArcadeDB versions before 26.8.1, specifically in the IMPORT DATABASE command. The security validator resolves hostnames but the connection re-resolves the raw URL, allowing for DNS rebinding or HTTP redirect attacks. Evidence is limited to public CVE details and vendor advisory information. Defenders should verify affected product deployments, review official advisories, and plan vendor-supported updates or mitigations.
