Microsoft patched CVE-2026-45659, an 8.8 CVSS deserialization remote code execution flaw in SharePoint Server Subscription Edition, 2019, and 2016. The bug only requires Site Member privileges, a trivially low bar given SharePoint history of being weaponized for mass exploitation.
Threat actors are mass-exploiting CVE-2026-26980, a critical SQL injection bug in Ghost CMS, to harvest Admin API keys and inject ClickFix malware loaders into more than 700 hijacked sites including Harvard, Oxford, Auburn, and DuckDuckGo. A patch has been available in version 6.19.1 since February.
Read moreA CVSS 10.0 zero-day in the LiteSpeed User-End cPanel Plugin lets any authenticated cPanel user execute arbitrary scripts as root via the lsws.redisAble JSON-API endpoint. LiteSpeed confirms active in-the-wild exploitation. Plugin versions 2.3 through 2.4.4 are vulnerable, with the fix shipped in 2.4.7.

Imperva is tracking 15,000+ attack attempts against nearly 6,000 sites across 65 countries. CISA added the bug to KEV on May 22 with a federal patch deadline of May 27, 2026.
Read moreCisco disclosed CVE-2026-20223, a maximum severity CVSS 10.0 flaw in Secure Workload that allows unauthenticated remote attackers to gain Site Admin privileges by sending crafted requests to internal REST API endpoints. The vulnerability crosses tenant boundaries on both SaaS and on-premises deployments, has no workarounds, and is fixed in releases 3.10.8.3 and 4.0.3.17.
Read moreMicrosoft confirmed on May 21 that CVE-2026-41091, a CVSS 7.8 link-following privilege escalation in the Microsoft Malware Protection Engine, and CVE-2026-45498, a denial-of-service flaw in the Defender Antimalware Platform, are both under active exploitation. CISA added both to the KEV catalog with a June 3 federal remediation deadline. Defender engine version 1.1.26040.8 and Antimalware Platform 4.18.26040.7 contain the fixes and ship automatically through definition updates.
Read moreMicrosoft published mitigation guidance for CVE-2026-45585, the YellowKey BitLocker bypass zero-day publicly disclosed by researcher Chaotic Eclipse last week. The flaw lives in the FsTx Auto Recovery Utility inside Windows Recovery Environment and lets anyone with physical access and a USB stick spawn an unrestricted shell with the BitLocker-protected volume already mounted. Windows 11 24H2, 25H2, 26H1 and Windows Server 2025 are affected.
Read moreA working zero-day exploit dubbed MiniPlasma escalates standard users to SYSTEM on fully patched Windows 11. It abuses cldflt.sys, the same Cloud Filter driver behind CVE-2020-17103 that Microsoft 'fixed' in 2020. PoC is public on GitHub. No patch yet. Assume compromise paths exist on every Windows endpoint until the next Patch Tuesday.
Read moreA heap buffer overflow lurking in NGINX's ngx_http_rewrite_module since 2008 went from coordinated disclosure to active in-the-wild exploitation in roughly seventy-two hours. CVE-2026-42945 affects every release from 0.6.27 through 1.30.0 across both Open Source and Plus, can crash worker processes trivially, and can reach remote code execution on hosts where ASLR is disabled. Patches are available in NGINX 1.30.1 and 1.31.0.
Read moreCisco patched CVE-2026-20182, a CVSS 10.0 authentication bypass in Catalyst SD-WAN Controller and Manager that lets an unauthenticated remote attacker gain administrative access via the vdaemon peering service on UDP/12346. CISA added the flaw to its Known Exploited Vulnerabilities catalog with a federal remediation deadline of May 17, 2026. Threat cluster UAT-8616 is actively exploiting it. No workarounds, only patches.
Read moreMicrosoft Exchange Server CVE-2026-42897 is a cross-site scripting flaw in Outlook Web Access that lets a crafted email execute JavaScript in the victim OWA session. CISA added it to the Known Exploited Vulnerabilities catalog on May 15, 2026 after confirmed in-the-wild exploitation, with a May 29 federal mitigation deadline. Exchange Server 2016, 2019, and Subscription Edition are affected. Exchange Online is not. Microsoft scored it CVSS 8.1, and patches shipped in the May 2026 security update.
Read moreA heap buffer overflow in NGINX ngx_http_rewrite_module has been hiding in the codebase since 2008. CVE-2026-42945 (CVSS 9.2) lets unauthenticated attackers hijack any unpatched NGINX instance. With NGINX powering over 30% of the internet, patch immediately.
Read moreMicrosoft shipped 138 patches including two unauthenticated remote code execution flaws rated CVSS 9.8. CVE-2026-41089 gives SYSTEM on domain controllers via Netlogon overflow. CVE-2026-41091 does the same via Windows DNS. Both are wormable. Patch now.
Read morecPanel and WHM are bleeding root through CVE-2026-41940, a CVSS 9.8 CRLF-injection authentication bypass that has been exploited in the wild since late February 2026. The April 28 patch is available now, but attackers running automated campaigns from over 2,000 source IPs have been deploying a cross-platform Go backdoor on compromised hosts for two months. Patch immediately and assume breach on any internet-exposed unpatched server.
Read moreIvanti has confirmed in-the-wild exploitation of CVE-2026-6973, an authenticated remote code execution flaw in on-premises Endpoint Manager Mobile rated CVSS 7.2. CISA added the bug to its Known Exploited Vulnerabilities catalog on May 7 and gave federal agencies until May 10, 2026 to remediate. The exploitation pattern strongly suggests reuse of admin credentials harvested during the unauthenticated EPMM compromises disclosed in January 2026.
Read morecPanel and WHM shipped fixes for three CVEs on May 8 including a CVSS 8.8 Perl code injection in the create_user API that lets authenticated attackers execute arbitrary system commands. If you run cPanel, update immediately — attackers are already watching.
Read moreTwo Linux kernel page-cache write bugs collectively named Dirty Frag let any unprivileged local user pop a root shell in one command. CVE-2026-43284 in xfrm-ESP was patched May 8. CVE-2026-43500 in RxRPC is still unpatched. Microsoft has already seen active exploitation in the wild and a public proof-of-concept is on GitHub.
Read moreCVE-2026-6973 is an authenticated RCE in on-prem Ivanti Endpoint Manager Mobile confirmed under active exploitation. CISA added it to the KEV catalog with a 3-day federal patch deadline. Over 850 internet-facing instances remain exposed. Check your MDM now.
Read moreApache HTTP Server 2.4.66 ships a double-free in mod_http2 that crashes worker processes with two HTTP/2 frames and no authentication. CVSS 8.8, DoS exploitation already in the wild, and a public PoC chain converts the bug to remote code execution on default Debian and Docker builds. The fix is in 2.4.67, released May 4.
Read moreCVE-2026-0300 is an unauthenticated buffer overflow in the PAN-OS User-ID Authentication Portal that grants root code execution on PA-Series and VM-Series firewalls. Palo Alto has confirmed limited in-the-wild exploitation against internet-exposed portals. CVSS scores 9.3 for internet-exposed deployments, 8.7 for trusted-network only. Patches roll out from May 13 through May 28, 2026.
