VulnOps
2026-09-12August 2026 Patch Tuesday brings critical RCE chains requiring immediate coordination, while multiple high-severity authorization and authentication bypasses across ConnectWise ScreenConnect, JFrog Artifactory, and GitLab demand urgent remediation prioritization. Vulnops practitioners face a concentrated wave of privilege escalation and access control vulnerabilities affecting widely-deployed infrastructure tools.
- →ConnectWise ScreenConnect CVE-2026-84869: Privilege Escalation via Authorization Bypass: Remote code execution through improper privilege management in a ubiquitous remote support tool requires immediate inventory and patching to prevent lateral movement and credential theft.
- →JFrog Artifactory Dual Authorization and Authentication Flaws (CVE-2026-42016, CVE-2026-42018): Token scope validation bypass and authentication bypass in artifact repositories expose supply chain integrity risks, requiring immediate token rotation and access control audits across CI/CD pipelines.
- →GitLab Path Traversal and Authentication Bypass (CVE-2026-85706): Path traversal combined with authentication bypass in Community and Enterprise editions threatens repository access controls and requires immediate version verification and patching.
Prioritize patch deployment for ConnectWise ScreenConnect, JFrog Artifactory, and GitLab today, then audit token scopes, privilege assignments, and authentication mechanisms across all three platforms to close active exploitation windows.
Today sees the publication of CVE-2026-63520, a high-severity remote code execution in Microsoft SharePoint. Discovered by Rapid7 Senior Principal Security Researcher Stephen Fewer, and published today in coordination with Microsoft; this vulnerability is the second in a pair of exploits which, when chained together, comprise a critical unauthenticated remote code execution vulnerability in a vulnerable SharePoint server. Patches are available for SharePoint Server Subscription Edition, 2019, [.
ConnectWise ScreenConnect contains both an improper privilege management and missing authorization vulnerability that may allow an attacker to file transfer and execution through an active remote sessions without authorization or host confirmation.
JFrog Artifactory contains an incorrect authorization vulnerability that allows leads to privilege escalation attack due to a validation check of the token signature/issuer and not the token’s scope.
JFrog Artifactory contains an improper authentication vulnerability that could return an internal anonymous-user token to an unauthenticated caller when anonymous access is disabled, potentially exposing sensitive resources.
GitLab Community Edition and Enterprise Edition contains a path traversal vulnerability that allows an unauthenticated user to read arbitrary files due to an improper path confinement and missing authentication enforcement in the repository commits API.
