Security Articles

Daily threat intelligence and vulnerability analysis from our security team. We publish expert breakdowns of critical CVEs, active exploits, and emerging attack campaigns as they happen.

Our analysts monitor vendor advisories, CISA alerts, and underground threat activity to give you actionable guidance you can use the same day. Filter by severity below to find what matters most to your environment.

Updated October 29, 2026 — all 245 published advisories are browsable here. The five drawing the most attention right now: North Korea’s Lazarus group breaching at least three companies through a fake job-candidate portfolio site that turned a trusted sign-in security plugin into the way in, then running its spying tools only in memory — there is no patch and no CVE, so remove security plugins nobody needs and tell HR and hiring managers that a polished résumé site followed by an “allow this plugin” prompt is a call to the security team, not a click; an attacker replaying stolen Microsoft 365 sign-in tokens (the pass Microsoft hands you after the password and multifactor prompt are already done) to take over 97 accounts at 79 organizations, registering rogue devices, swapping the multifactor app and hiding emails about payroll, direct deposit and bank details with inbox rules — there is no patch, because nothing is broken, and a password reset alone does not evict the attacker, so after any mailbox compromise also remove unknown devices and multifactor methods and check for hidden inbox rules; Apple finally fixing an actively exploited iPhone and iPad flaw on older devices that cannot run the newest iOS, a bug in how the device draws images that lets a booby-trapped file run an attacker’s code (CVE-2026-86950, rated 8.8 out of 10, on CISA’s actively exploited list since September 29) — the iPhone XS, XS Max and XR and several older iPads went about four weeks with no fix at all, and those hand-me-down phones and lobby tablets are the devices nobody checks, so find anything still on iOS 18 and update it to 18.7.11 this week; two emergency fixes for PHP, the language running underneath WordPress and most small-business websites and customer portals, after flaws nicknamed PHP2Shell let someone with no login take over the server (CVE-2026-109618 and CVE-2026-109619, each rated 9.2 out of 10) — attackers began trying them before the fixes shipped, and a fully patched website does not help if the PHP underneath it is old, so ask your web host or developer to confirm you are on PHP 8.5.12, 8.4.27, 8.3.36 or 8.2.35; and attackers planting backdoors on Nextcloud file-sharing servers through the built-in Collabora document-editing add-on, with no login, then hunting the company files for password vaults and crypto wallets (CVE-2026-110447, rated 9.2 out of 10, now on CISA’s actively exploited list) — the fix shipped September 11 but the warning only went out October 14, so update the add-on to 26.4.303 or remove it, then check for a backdoor, because on a server that was already hit the update is the start of the cleanup, not the end. Four of the five have already been used in real attacks, attackers are already trying the fifth, and for three of them (Lazarus, Microsoft 365 and Collabora) an update or a password reset alone does not make you safe. The cost is decided by how fast someone notices. If nobody is reading the alerts at 2 a.m., our 24/7 staffed security operations center handles the detection and the response.

CRITICAL: FreeIPA CVE-2026-76578 Gives Anonymous Clients Admin Rights

FreeIPA CVE-2026-76578 lets an unauthenticated LDAP client create a Kerberos principal of its own choosing and land it in the administrators group, with no credentials and no prior access required. Red Hat rates it 9.8 critical and reproduced the chain against default installations. FreeIPA 4.13.4 fixes it, while the 389 Directory Server half of the chain is still catching up across platforms.

CRITICAL: Magento and Adobe Commerce Zero-Day Exploited With No Patch Available

Attackers are actively exploiting an unpatched remote code execution flaw in Magento Open Source and Adobe Commerce that Sansec has named StyleSmuggler. Every current version is affected including 2.4.9, exploitation began on September 4, and Adobe has not published a CVE, an advisory, or a fix. The chain ends in a persistent Rust backdoor disguised as a kernel thread.

CRITICAL: Cisco Nexus 9000 CVE-2026-20212 Allows Unauthenticated Root RCE

Cisco patched CVE-2026-20212, a CVSS 9.8 flaw in Nexus 9000 Series switches built on Silicon One ASICs that lets an unauthenticated remote attacker execute code as root. The S1HAL process listens on TCP ports 43210 and 43211 through the default Layer 3 VRF, and NX-OS releases 10.3(1) through 10.6(3s) are affected. Upgrade to 10.6(4) or later, or apply an infrastructure access control list.

CRITICAL: Ruby on Rails CVE-2026-66066 Exploited in the Wild

Attackers are actively exploiting CVE-2026-66066, the CVSS 9.5 Active Storage flaw in Ruby on Rails nicknamed KindaRails2Shell, with VulnCheck detections jumping from 50 to 360 in under two days. A crafted image upload gives an unauthenticated attacker arbitrary file read and a path to remote code execution. Patched in Active Storage 7.2.3.2, 8.0.5.1, and 8.1.3.1, and the fix also requires libvips 8.13 or newer.

CRITICAL: Windows IKE Flaw CVE-2026-33824 Under Active Exploitation

CISA added CVE-2026-33824 to the Known Exploited Vulnerabilities catalog on August 18 after Unit 42 observed hands on keyboard attacks against Windows IKE VPN endpoints. The CVSS 9.8 double free in the Windows IKE Service Extensions gives unauthenticated attackers SYSTEM level code execution over UDP 500 and 4500. Microsoft patched it in April 2026 and federal agencies must remediate by August 21.

CRITICAL: Ray CVE-2025-62593 Added to CISA KEV After Active Exploitation

CISA added CVE-2025-62593 to its Known Exploited Vulnerabilities catalog on August 17, 2026, giving federal civilian agencies until August 20 to remediate. The critical 9.4 flaw in the Ray distributed AI framework lets a malicious web page reach an otherwise unexposed Ray dashboard through DNS rebinding and execute arbitrary code. The RondoDox botnet weaponized it two days before public disclosure, and every version before Ray 2.52.0 is affected.

CRITICAL: SharePoint CVE-2026-55040 Exploited After Public PoC Release

Microsoft patched CVE-2026-55040 in July 2026, a CVSS 9.1 authentication bypass in on-premises SharePoint Server that chains four JWT validation failures to let an unauthenticated attacker forge tokens and impersonate any user, including administrators. Rapid7 published a working proof of concept on August 11 and honeypots recorded exploitation attempts roughly one day later. SharePoint Server 2016, 2019, and Subscription Edition are all affected.

HIGH: WordPress 7.0.3 Fixes Pre-Auth XSS Chaining to PHP Code Execution

WordPress 7.0.3 patches CVE-2026-64638, a pre-authentication cross-site scripting flaw on the login screen that researchers chained all the way to PHP code execution on the server. The CVSS 8.9 bug comes from a parser disagreement between strip_tags and KSES, affects every maintained version before 7.0.3, and was backported to the 4.7 branch. No confirmed exploitation in the wild yet, but the full technique is public.
