CISA is aware of critical authentication bypass vulnerability CVE-2026-102764, affecting BeyondTrust Remote Support (formerly Bomgar) versions 26.2.3 and earlier. Patches are available for supported versions (24.3.1 and later); organizations using older versions must upgrade first. Cyber threat actors are actively exploiting the vulnerability to gain initial access, then establishing persistence, escalating privileges, and moving laterally. CISA added CVE-2026-102764 to its Known Exploited Vulnerabilities (KEV) catalog on Oct. 16, 2026.  CISA urges organizations with affected self-hosted Remote Support appliances to immediately take the following actions:  Apply the BT26-05-RS patch, as outlined in BeyondTrust’s Security Advisory BT26-05. Organizations on a self-hosted Remote Support version older than 24.3.1 will need to upgrade to a newer version to apply the patch. Organizations using BeyondTrust-hosted (SaaS) Remote Support deployments have already been patched. Review BeyondTrust’s blog ARMORY CASTLE and BT26-05: What Security Teams Need to Know for detailed information on the vulnerability and recommended response and mitigation actions.  Limit external access to the Remote Support appliance to the services needed to support users and customers. Restrict access to administrative interfaces to trusted networks. Review BeyondTrust’s B Series Appliance on-premises security for additional guidance on securing network connectivity for self-hosted Remote Support appliances.  Organizations with affected self-hosted Remote Support appliances should conduct network and m

CISA has added two new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2025-61624 Fortinet Multiple Products Path Traversal Vulnerability CVE-2026-102764 BeyondTrust Remote Support Authentication Bypass by Spoofing Vulnerability  These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.  Binding Operational Directive (BOD) 26-04: Prioritizing Security Updates Based on Risk establishes vulnerability management requirements for Federal Civilian Executive Branch (FCEB) agencies. BOD 26-04 reinforces the importance of the KEV Catalog and requires federal agencies to prioritize rapid remediation of high-risk vulnerabilities, specifically those identified by Common Vulnerabilities and Exposures (CVEs) listed in CISA’s KEV Catalog on publicly exposed assets that grant total control of the asset post-exploitation, while deferring action for lower-risk vulnerabilities. BOD 26-04 further establishes basic expectations for when agencies must check whether threat actors compromised the system before the patch was applied.  While BOD 26-04 applies only to FCEB agencies, CISA encourages all organizations to adopt risk-based vulnerability management and prioritize remediation of KEV Catalog vulnerabilities. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.  Aware of an exploited vulnerability not currently listed in the KEV Catalog?

CISA and the Federal Bureau of Investigation (FBI) released a Public Service Announcement (PSA) warning election and campaign officials about cyber threats during the 2026 U.S. midterm elections. Malicious cyber actors may use phishing and smishing techniques to steal login credentials and other sensitive information or install malware on targeted devices. Election officials, candidates, and political organizations may be attractive targets because of their access to voter registration data, current government officials, and sensitive campaign information. Cyber actors are increasingly using sophisticated phishing and smishing campaigns that closely resemble legitimate communications. These efforts may include convincing emails, text messages, audio, and video content designed to manipulate recipients into disclosing sensitive information or interacting with malicious links and attachments. CISA and the FBI urge election officials, campaign personnel, and the public to review the PSA, follow recommended cybersecurity practices, and remain vigilant for suspicious emails and mobile messages.
