Vulnerabilities
The researcher behind a six-week run of uncoordinated Microsoft zero-day disclosures pledged a July 14, 2026 'bone-shattering' Windows exploit drop. Microsoft signaled law-enforcement action and pulled the researcher's GitHub account. Both sides have hardened.
Vulnerabilities
Rapid7 Labs disclosed an unpatched CVSSv4 9.4 argument-injection (CWE-88) flaw in Gogs that lets any authenticated user achieve remote code execution by injecting --exec into git rebase via a malicious branch name. The second critical self-hosted-Git flaw in one week.
Vulnerabilities
Microsoft's MSRC publicly condemned a six-flaw run of uncoordinated zero-day disclosures, saying the leaks put customers at 'unnecessary risk.' It's a position shift after six weeks of researcher disclosures that forced emergency response. The story is the tension itself.
Vulnerabilities
Gitea disclosed CVE-2026-27771, a registry authorization flaw that lets unauthenticated attackers pull private container images from any self-hosted Gitea below 1.26.2. It collapses the security premise of self-hosting: keeping images off public registries.
Vulnerabilities
Google's Threat Intelligence Group caught attackers exploiting CVE-2026-5426, a hardcoded ASP.NET machineKey in Digital Knowledge's KnowledgeDeliver LMS, to forge ViewState payloads, drop the Godzilla web shell, and stage Cobalt Strike Beacon. The patch alone is not enough.
Vulnerabilities
Microsoft patched CVE-2026-45659, a CVSS 8.8 deserialization RCE in SharePoint Server. The 'authenticated' precondition is barely a precondition — any account with Site Member, the lowest SharePoint role, can trigger it. Patch this week.
Vulnerabilities
Attackers are exploiting CVE-2026-26980, a CVSS 9.4 SQL-injection flaw in Ghost CMS, to hijack more than 700 websites — Harvard, Oxford, and DuckDuckGo among them — and serve visitors a fake-CAPTCHA ClickFix lure. The flaw was patched three months ago.
Vulnerabilities
Researchers at ADAMnetworks disclosed Underminr, a domain-fronting-style flaw they say affects roughly 88 million domains. Its defining property is invisibility: because the TLS SNI and HTTP Host header match, the CDN-side checks built to kill domain fronting never trigger.
Vulnerabilities
CVE-2026-48172, a CVSS 10.0 flaw in the LiteSpeed User-End cPanel plugin, lets anyone with a valid cPanel account run code as root. LiteSpeed confirms it is being actively exploited. On shared hosting, one cheap account is now a path to every account on the server.

Vulnerabilities
Ubiquiti has patched three maximum-severity flaws in UniFi OS — the operating system behind its gateways, Dream Machines, and network video recorders. All three are rated CVSS 10.0, and all three are remotely exploitable by an attacker with no privileges.
Vulnerabilities
Trend Micro's own Incident Response team discovered CVE-2026-34926, a directory-traversal zero-day in Apex One, while it was being exploited. CISA added it to the KEV catalog with a June 4 federal deadline. Its modest 6.7 CVSS score conceals an environment-wide blast radius.
