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 . ...

A suspected advanced threat actor has been observed exploiting a security flaw in Fortinet FortiOS to deliver a previously unreported memory-resident ARM64 malware known as PEERSTITCH. The attack involves the exploitation of CVE-2025-61624 (CVSS score: 5.4), a path traversal flaw in the command line interpreter of FortiOS, FortiPAM, FortiProxy, and FortiSwitchManager that could allow a

FortiOS, FortiPAM, FortiProxy, and FortiSwitchManager contain a path traversal vulnerability that may allow an authenticated attacker with admin profile and at least read-write permissions to write or delete arbitrary files via specific CLI commands.
