CISA says attackers are exploiting a critical SharePoint deserialization flaw. Patching closes the bug, but exposed servers also need a focused compromise assessment.
ESET Research found 11 old UEFI shim bootloaders, all validly signed by Microsoft, that bypass Secure Boot on any system trusting Microsoft's third-party CA. CVE-2026-8863 and CVE-2026-10797 — no exploit chain required.
IPV6_FRAG_ESCAPE is a Linux kernel 6.12 privilege escalation with public PoC code, no CVE at disclosure time, and a practical path from container user to host root.
CVE-2026-46331 and CVE-2026-43503 both corrupt the Linux page cache via network subsystems to grant root — bypassing file integrity tools like AIDE and Tripwire without touching files on disk.
A critical, unauthenticated RCE in Oracle PeopleSoft let ShinyHunters compromise universities and other organizations for weeks before Oracle's advisory caught up. Google notified 100+ potentially exposed organizations. The technical breakdown, IOCs, and what to hunt for.
GreatXML is a public BitLocker-bypass PoC claim involving WinRE, Defender Offline Scan state, and unattend.xml. The defensive lesson is bigger than one repository: recovery environments are security boundaries.
RoguePlanet is the latest public Nightmare Eclipse proof-of-concept targeting Microsoft Defender. The code points to a race condition that turns Defender cleanup behavior into SYSTEM execution.
CVE-2026-46333 (ssh-keysign-pwn) is a nine-year-old Linux kernel race condition that lets an unprivileged local user steal SSH host keys and dump /etc/shadow. Root command execution is also possible on specific configurations.
A researcher discovered a zero-day that bypasses BitLocker encryption on Windows 11 using a USB stick and the recovery environment — and suspects the component may be intentional. CVE-2026-45585, CVSS 6.8. Microsoft released an official mitigation on May 21, 2026.
Microsoft's on-prem Exchange Server has an actively exploited XSS zero-day (CVSS 8.1). A single crafted email in OWA triggers arbitrary JavaScript — here's how it works and how to stop it.
Two new Linux kernel vulnerabilities — Dirty Frag (CVE-2026-43284/43500) and Copy Fail (CVE-2026-31431) — enable local privilege escalation to root on nearly all major distros. What users and admins need to know.
