The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added five security flaws impacting JFrog Artifactory, ConnectWise ScreenConnect , and MikroTik RouterOS to its Known Exploited Vulnerabilities ( KEV ) catalog, following reports of active exploitation in the wild. Details of the vulnerabilities are as follows - CVE-2026-42016 (CVSS score: 8.1) - An incorrect authorization vulnerability in JFrog Artifactory that could lead to privilege escalation due to a validation check of the token signature/issuer and not the token's scope. CVE-2026-42018 (CVSS score: 7.5) - An improper authentication vulnerability in JFrog Artifactory that could return an internal anonymous-user token to an unauthenticated caller when anonymous access is disabled, potentially leaking sensitive resources. CVE-2026-84869 (CVSS score: 9.9) - An improper privilege management and missing authorization vulnerability in  ConnectWise ScreenConnect that could allow an attacker to fil...

The "major malicious attack" that targeted RubyGems in May 2026 was the work of a swarm of OpenAI agents, according to a new report published by researchers Spencer Kitts, Thomas Larsen, and Sydney Von Arx. On May 12, Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, disclosed details of a coordinated cyber attack that targeted the package manager for the Ruby programming language with hundreds of junk gems, prompting the maintainers to suspend new user sign-ups for about four days. In a follow-up analysis, Socket highlighted a campaign dubbed GemStuffer that involved a cluster of more than 150 gems that used the package registry as a data exfiltration channel and staged public data scraped from U.K. local government democratic services portals. At that time, the software supply chain security company noted the activity shares the "same abuse pattern" as the broader RubyGems spam-publishing incident. "It's not...

GitLab has released patches to address multiple flaws, including a maximum-severity security vulnerability that has witnessed in-the-wild probes within hours of public disclosure. The vulnerability in question is CVE-2026-85706 (CVSS score: 10.0), a path traversal issue in the repository commits API that could allow an unauthenticated user to read arbitrary files from the GitLab server under certain conditions. The problem, per GitLab, stems from "improper path confinement and missing authentication enforcement in the repository commits API." The issue impacts the following versions of GitLab Community Edition (CE) and Enterprise Edition (EE) - All versions from 18.7 before 19.1.8,  All versions from 19.2 before 19.2.6, and  All versions from 19.3 before 19.3.2 According to preemptive exposure management firm watchTowr, the vulnerability is already witnessing active in-the-wild probes since 06:00 UTC on September 11, 2026. The issue, it said, allows an ...

Security teams have become exceptionally talented at finding vulnerabilities. Now, it’s time to turn our attention to optimizing the process for determining which of those vulnerabilities actually create a path to compromise. A critical vulnerability may look alarming on a scanner report, but if it sits behind strong segmentation, identity controls, and other defenses that prevent an attacker from reaching anything important, then it doesn’t necessarily need immediate attention.  On the other hand, a medium-severity vulnerability may appear less important, but if it can be used to provide a foothold that can be chained with other weaknesses to reach sensitive data or privileged systems, then fixing that gap becomes a priority. How Autonomous Penetration Testing Reveals What Attackers Can Actually Exploit Severity scores tell you what vulnerabilities could mean in isolation. Autonomous penetration testing tells you what an attacker can actually do with the vulnerabilities....

Attackers have chained two flaws in JFrog Artifactory , the repository that software build pipelines pull from, to take administrator control of self-hosted servers and plant backdoors, cloud security company Wiz said in a report. Wiz saw the attacks between August 15 and September 8. JFrog had fixed both flaws before then, so only servers that had not been updated were open to them. Neither flaw gives administrator control on its own. CVE-2026-42018 makes Artifactory hand an internal anonymous-user token to a caller who has not logged in, even when anonymous access is turned off. CVE-2026-42016 then allows that low-privilege token to be swapped for one with administrator scope, because Artifactory checks a token's signature and who issued it, but not what the token is allowed to do. Every case Wiz saw followed a similar pattern. The attacker sent an unauthenticated request to a token endpoint and received a token for the internal anonymous user, then exchanged it ...
