CVE-2026-47682 cvat-ai CVE debrief

Who should care

Defenders managing CVAT instances, especially those with cloud storage integrations, should assess exposure and apply the patch. The vulnerability allows an attacker to overwrite arbitrary server files, requiring defenders to verify exposure and apply the patch. Defenders should prioritize verifying exposure and applying the patch, as an attacker with write access to a cloud storage added to a CVAT instance can overwrite arbitrary server files.

Why it matters

CVE-2026-47682 allows an attacker with write access to cloud storage in CVAT instances to overwrite arbitrary server files, requiring defenders to verify exposure and apply the patch.

• Potential for data tampering and integrity loss
• Risk of unauthorized file modifications
• Need for verification of instance configurations and patch application

Technical summary

CVAT versions 1.6.0 through 2.64.0 are vulnerable to arbitrary file overwrite by an attacker with write access to a cloud storage added to the instance. The vulnerability allows an attacker to overwrite arbitrary server files, requiring defenders to verify exposure and apply the patch. The vulnerability has been fixed in version 2.65.0. Defenders should prioritize verifying exposure and applying the patch, as an attacker with write access to a cloud storage added to a CVAT instance can overwrite arbitrary server files.

Defensive priority

Defenders should prioritize verifying exposure and applying the patch, as an attacker with write access to a cloud storage added to a CVAT instance can overwrite arbitrary server files.

Recommended defensive actions

• Verify CVAT instance exposure and cloud storage configurations
• Apply the patch to version 2.65.0
• Monitor for suspicious file modifications
• 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 CVE record and NVD entry provide details on the vulnerability, but its scope and remediation require verification from official sources. The vulnerability has been fixed in version 2.65.0. Defenders should prioritize verifying exposure and applying the patch, as an attacker with write access to a cloud storage added to a CVAT instance can overwrite arbitrary server files. The CVAT instance's cloud storage configurations and patch application need to be verified.
