- CISA lists CVE-2026-42016, CVE-2026-42018, and CVE-2026-84869 as exploited in the wild.
CISA has added three vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on confirmed evidence of active exploitation. Two affect JFrog Artifactory: CVE-2026-42016 (incorrect authorization) and CVE-2026-42018 (improper authentication), which could allow attackers to bypass access controls on artifact repositories used in software build and deployment pipelines. The third, CVE-2026-84869, affects ConnectWise ScreenConnect and involves improper privilege management combined with missing authorization checks — a remote support/access tool commonly deployed by MSPs and IT help desks, making it an attractive target for privilege escalation and lateral movement.
Under Binding Operational Directive (BOD 26-04), FCEB agencies must prioritize rapid remediation of KEV-listed vulnerabilities on publicly exposed assets that grant total control of the asset post-exploitation, and must verify whether systems were compromised prior to patching. While the directive is binding only on federal civilian agencies, CISA recommends all organizations using JFrog Artifactory or ConnectWise ScreenConnect apply available patches immediately and check for signs of prior compromise, given confirmed in-the-wild exploitation.
No specific threat actor, malware family, or technical exploitation details were disclosed in this bulletin. Organizations running affected versions of Artifactory or ScreenConnect should treat these as high-priority patching items, particularly where instances are internet-facing, and review authentication and authorization logs for anomalous access consistent with privilege escalation or authentication bypass.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
