U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Oracle PeopleSoft Enterprise PeopleTools flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added Oracle PeopleSoft Enterprise PeopleTools flaw, tracked as CVE-2026-35273 (CVSS score of 9.8), to its Known Exploited Vulnerabilities (KEV) catalog. Oracle PeopleSoft Enterprise PeopleTools is the underlying technology platform […]

CISA has added one new vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog , based on evidence of active exploitation. CVE-2026-35273 Oracle PeopleSoft Enterprise PeopleTools Missing Authentication for Critical Function Vulnerability This type of vulnerability is a frequent attack vector for malicious cyber actors and poses 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, updating BOD 22-01 . 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 Known Exploited Vulnerabilities (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 ...
