CISA KEV Adds Two Chained AhsayCBS Vulnerabilities
Tech GuruQuick Answer
CISA added CVE-2026-105133 and CVE-2026-105134 to KEV on October 14. Ahsay says earlier patches were incomplete; apply 10.3.4.45 to affected version 10 systems or 9.15.2.70 to versions 7 through 9, reboot, validate, and retain forensic and change evidence.
Confirm Scope And Apply The Supported Remediation
What to do now: Inventory AhsayCBS servers and branches, preserve logs before change, deploy the matching Ahsay hotfix, reboot as directed, confirm the resulting build and service health, and review the exposed API paths for suspicious activity.

| Affected versions | AhsayCBS 10 deployments below hotfix 10.3.4.45 and AhsayCBS 7, 8, or 9 deployments below hotfix 9.15.2.70, as stated in Ahsay's updated alert. |
| Fixed version | AhsayCBS 10.3.4.45 for version 10; AhsayCBS 9.15.2.70 for versions 7, 8, and 9; reboot after applying the matching hotfix |
| CVSS base score | Not provided by the authority |
| CVSS severity | Not provided by the authority |
| Exploitation status | CISA confirms evidence of active exploitation for both CVEs; ransomware use is unknown.; no exploitation claim is inferred. |
What Changed
CISA added the chained authentication-bypass and command-injection vulnerabilities to KEV. Ahsay states its earlier hotfixes were incomplete and supplies replacement hotfixes for the affected version streams.
What To Validate Now
- Inventory. Locate AhsayCBS versions 7, 8, 9, and affected version 10 installations deployments, versions, enabled features, exposure paths, owners, and dependent services.
- Establish applicability. Compare each deployment with the authority's affected-version statement: AhsayCBS 10 deployments below hotfix 10.3.4.45 and AhsayCBS 7, 8, or 9 deployments below hotfix 9.15.2.70, as stated in Ahsay's updated alert. Do not infer applicability from product family or severity alone.
- Remediate. Apply AhsayCBS 10.3.4.45 for version 10; AhsayCBS 9.15.2.70 for versions 7, 8, and 9; reboot after applying the matching hotfix through the supported vendor or project channel, following the current advisory and change-control requirements.
- Validate. Confirm the resulting version or managed-service state, exercise representative functionality and recovery paths, monitor for regressions, and document exceptions.
- Retain evidence. Preserve asset and owner identifiers, the applicability decision, before-and-after versions, change approval, installation output, validation results, and any exception or rollback record.
Operational Cautions
Do not apply a hotfix from the wrong branch. The CISA KEV due date is October 17, 2026 for in-scope federal systems; other organizations should use their own risk and incident-response process. Preserve the authority snapshot, asset and owner records, before-and-after versions, change approval, installation output, validation results, exceptions, and rollback evidence.
Evidence To Retain
- Exact product, release stream, package or application version, enabled feature, environment, and accountable owner.
- UTC timestamps, authority revision, approved change record, installer or package-manager output, and resulting version.
- Relevant logs and monitoring evidence, test results, exceptions, compensating controls, and rollback decisions.
