CVE-2026-1727
📋 TL;DR
This vulnerability allows attackers to access sensitive information by predicting Google Cloud Storage bucket names used by the Agentspace service for error logs and temporary data staging. Attackers can perform 'bucket squatting' by creating these predictable buckets before legitimate use. Only users of Agentspace service versions after December 12th, 2025 are affected.
💻 Affected Systems
- Agentspace service
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete exposure of sensitive error logs and imported data including potentially confidential information, credentials, or proprietary data.
Likely Case
Unauthorized access to error logs containing system information, partial data exposure from staging operations.
If Mitigated
No data exposure if buckets are properly secured with access controls and monitoring.
🎯 Exploit Status
Bucket squatting requires predicting naming patterns and creating buckets before legitimate use. No authentication bypass needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest version as of advisory date
Vendor Advisory: https://docs.cloud.google.com/gemini/enterprise/docs/release-notes#February_06_2026
Restart Required: No
Instructions:
1. Update to latest Agentspace service version. 2. No user action required according to vendor.
🔧 Temporary Workarounds
Manual bucket naming override
allConfigure Agentspace to use random or custom bucket names instead of predictable patterns
# Configuration depends on specific Agentspace implementation
Bucket access restrictions
allApply strict IAM policies and bucket permissions to prevent unauthorized access
gsutil iam ch -d allUsers gs://BUCKET_NAME
gsutil iam ch -d allAuthenticatedUsers gs://BUCKET_NAME
🧯 If You Can't Patch
- Implement strict bucket naming policies with randomness
- Enable bucket versioning and logging to detect squatting attempts
- Regularly audit GCS bucket permissions and ownership
🔍 How to Verify
Check if Vulnerable:
Check if using Agentspace service version after Dec 12, 2025 and if using predictable GCS bucket naming patternsCheck Version:
# Check Agentspace service version through service-specific commandsVerify Fix Applied:
Verify updated to latest version and confirm bucket names are no longer predictable📡 Detection & Monitoring
Log Indicators:
- Unexpected bucket creation events
- Access logs showing data retrieval from unfamiliar buckets
- Failed data import operations due to bucket conflicts
Network Indicators:
- DNS queries for predictable bucket names
- HTTP requests to suspected squatting buckets
SIEM Query:
source="gcp_audit" (resource.type="gcs_bucket" AND protoPayload.methodName="storage.buckets.create") | where protoPayload.request.bucket.name matches "predictable-pattern*"
