How to fix it
CVE-2026-15968 affects MOVEit Transfer and involves cross-site scripting. Successful exploitation may run attacker-controlled script in a trusted user's browser and expose session or application data. Prioritize internet-facing, privileged, automation, and production deployments. Upgrade MOVEit Transfer to 2025.1.5, 2026.0.3 or a later vendor-supported fixed release.
- Inventory every deployment, device, package, plugin, container, build, and environment that uses MOVEit Transfer.
- Compare the installed version with the recorded affected range: < 2025.1.5, < 2026.0.3.
- Upgrade MOVEit Transfer to 2025.1.5, 2026.0.3 or a later vendor-supported fixed release.
- Until patched, reduce public exposure, disable the affected workflow where practical, and allow access only from trusted users and systems.
- Review configuration, roles, tokens, network paths, and exposed endpoints connected to MOVEit Transfer; remove access that is not required.
- Review submissions, stored content, administrator activity, CSP reports, and web logs for script payloads or suspicious browser requests.
- If exploitation is suspected, isolate affected assets, preserve evidence, rotate exposed credentials or keys, restore trusted data, and rebuild compromised systems before returning them to service.
