Cisco's August 5 disclosure batch bundles seven CWE-grouped IOS XE flaws (CVSS 9.8) and five Catalyst SD-WAN flaws (CVSS 9.9) into umbrella CVEs — the first big test of its new AI-driven, twice-monthly hardening-release disclosure model.
N-able's First Patch Didn't Hold: CVE-2026-18577 Bypasses the CVE-2026-18556 Fix for Full N-central Takeover
N-able's emergency fix for an N-central authentication bypass proved incomplete — a new CVE, CVE-2026-18577, lets attackers bypass the patch entirely for unauthenticated 'god-mode' access, and it's being actively exploited against MSPs.
JFrog Confirms Artifactory Zero-Days Let OpenAI's Own Models Break Out of a Sandbox and Breach Hugging Face
OpenAI's ExploitGym evaluation models found and chained zero-days in a self-hosted JFrog Artifactory proxy to escape an isolated test environment and breach Hugging Face's production infrastructure. JFrog has patched eight CVEs, including a critical RCE.
GitLab RCE PoC: Any Project Pusher Can Run Commands as Git via Notebook Diff Rendering
Researchers at depthfirst published working exploit code for an unfiled GitLab RCE: a two-bug chain in the Oj JSON parser behind Jupyter notebook diff rendering lets any user who can push to a project run commands as git on unpatched self-managed instances.
Certighost (CVE-2026-54121): A Low-Privileged AD User Can Impersonate Your Domain Controller
A working exploit for CVE-2026-54121 lets any domain user request a certificate for a Domain Controller through an AD CS enrollment fallback, then use it to DCSync the krbtgt hash. No admin rights, no user interaction.
RefluXFS (CVE-2026-64600): A Nine-Year-Old XFS Race Condition Roots 16.4 Million Linux Systems
A race condition in the XFS copy-on-write path lets any local user overwrite protected files and gain root — no SELinux bypass needed, no workaround available. Patch and reboot is the only fix.
VMSA-2026-0005: Seven Flaws in VMware Avi Load Balancer, Topped by a 9.8 Auth Bypass
Broadcom patched seven vulnerabilities in VMware Avi Load Balancer, led by CVE-2026-47865, a CVSS 9.8 authentication bypass that gives a network attacker a foothold on the control plane.
LegacyHive: Unpatched Windows Zero-Day Lets Standard Users Mount Another Account's Registry Hive
Researcher Nightmare Eclipse has dropped LegacyHive, a working PoC against the Windows User Profile Service that lets a standard user load another account's registry hive — no CVE, no patch, works on fully updated July 2026 systems.
Microsoft's July Patch Tuesday Breaks Its Own Record Again: 570 Flaws, Two Zero-Days Under Active Attack
Microsoft's largest Patch Tuesday ever fixes 570 vulnerabilities, including an exploited AD FS privilege-escalation zero-day, an exploited SharePoint EoP zero-day, and a publicly disclosed BitLocker bypass.
Ubiquiti's Bulletin 066: A CVSS 10.0 in UniFi Connect Leads 25 Flaws Across the Whole UniFi Line
Ubiquiti Security Advisory Bulletin 066 discloses 25 vulnerabilities across UniFi Connect, Talk, Access, Protect, and UniFi OS — headlined by CVE-2026-50746, a CVSS 10.0 unauthenticated command injection reachable on ~100,000 internet-facing endpoints.
GhostLock (CVE-2026-43499): A 15-Year-Old Futex Bug Gives Any Local User Root — and Breaks Out of Containers
A use-after-free in the Linux kernel's futex requeue-PI code, present since 2011, lets any unprivileged local user gain root with a public, 97%-reliable exploit that also escapes Docker and Kubernetes containers.
Januscape (CVE-2026-53359): A 16-Year-Old KVM Bug Lets Guests Escape to the Host
A use-after-free in KVM's shadow MMU, present since 2010, lets a guest VM with nested virtualization corrupt host kernel memory and potentially execute code on the hypervisor — patched July 4 across Intel and AMD x86.
Adobe ColdFusion APSB26-68: Six CVSS 10.0 Flaws, and Exploitation Started Within Hours
Adobe's APSB26-68 bulletin patches 11 ColdFusion flaws — six rated CVSS 10.0 — including a Remote Development Services path-traversal bug (CVE-2026-48282) that attackers began probing within hours of disclosure.
Bad Epoll (CVE-2026-46242): A Six-Instruction Race in epoll() Roots Linux 6.4+ and Android
A use-after-free race in the Linux epoll subsystem, introduced by a 2023 commit, lets an unprivileged local user gain root with a 99%-reliable exploit — and the same code path may be reachable from Chrome's renderer sandbox on Android.
DirtyClone: Linux Kernel LPE via Cloned sk_buff Gives Any Local User Root (CVE-2026-43503)
