Two CVSS 9.8 Auth Bypasses in miniOrange SAML WordPress Plugin Were Exploited Before Any Database Even Listed the Paid Editions as Vulnerable

Attackers actively exploit two CVSS 9.8 auth bypasses (CVE-2026-61979, CVE-2026-15981) in the miniOrange SAML WordPress plugin, forging SAML responses to become admin.

CVE-2026-61979 is a SAML algorithm confusion flaw that lets attackers sign forged assertions using the identity provider's RSA public key as an HMAC secret; CVE-2026-15981 stems from PHP treating openssl_verify()'s -1 error return as true, allowing a crafted signature that triggers an OpenSSL error to validate. Both bugs independently let unauthenticated attackers obtain WordPress administrator sessions and both are confirmed exploited in the wild. DigitalOcean discovered the exploitation via a network anomaly after public vulnerability databases covered only the Free edition (fixed in 5.4.5), leaving seven independently versioned paid editions appearing patched. Attackers are scanning SSO endpoints from six IPs in Belgium, Nigeria, the US and Germany, and paid-edition fixes require manual uploads across version lines.

One Exploit Chain, Two Espionage Campaigns: Chrome and Windows Under Fire

Two China-linked APT groups reused identical Chrome/Windows zero-day chain against NGOs, deploying GRIMWIDGE backdoor and LONGTALE credential-stealing extension.

Volexity reports that China-linked actors UTA0560 and JungleBamboo (APT31/TA412) ran byte-identical Chrome/Windows exploit chains against NGOs starting September 1, 2026, combining Chrome type confusion CVE-2026-85046, WebAssembly sandbox escape CVE-2026-87491, and Windows kernel flaw CVE-2026-85880. The Chrome bug was fixed in Chromium source but not yet shipped to Chrome users, making it an effective zero-day with an unusual patch gap. UTA0560 delivered the in-memory GRIMWEDGE JScript backdoor, while JungleBamboo deployed the SUPERSTOMP loader installing LONGTALE, a malicious Chrome extension disguised as Google Gemini that steals cookies, session tokens, and keystrokes. Volexity assesses with low confidence the exploit chain was sold or shared among different Chinese end-users.

Hackers Exploit FortiGate SSL-VPN Vulnerability to Attack Broadband Provider

Exposed attacker staging server reveals intrusion of Thai broadband provider 3BB via actively exploited FortiGate SSL-VPN flaw CVE-2024-21762.

Hunt.io found an open directory on server 92.63.180[.]133 holding 298 files detailing an intrusion into Triple T Broadband's 3BB brand, starting from a FortiGate 60F SSL-VPN at mail.3bb.co[.]th:10443. The actor weaponized CVE-2024-21762 (CVSS 9.8, KEV-listed since February 2024) using heap spraying and a ROP chain to gain a reverse shell. Post-exploitation included MeshCentral root-level persistence via www.ayuthayatech[.]com, Dirty COW/PwnKit privilege escalation, credential harvesting, SSH spraying against 55+ internal addresses, and log-deleting cleanup scripts; a stolen OpenVPN certificate and key from Triple T's PKI may still be valid.

Weekly Cybersecurity Newsletter Bulletin – Microsoft 0-day, FortiOS, PAN-OS Flaw, Revolut Data Breach, and 20+ Stories

Weekly roundup: Microsoft patches 973 flaws including two actively exploited zero-days; FortiOS CAPWAP flaw deploys PivotC2 RAT; PAN-OS root RCE disclosed.

Microsoft's September 2026 Patch Tuesday fixed 973 vulnerabilities, including two zero-days under active exploitation: CVE-2026-85880 (Windows ALPC) and CVE-2026-81963 (Windows Update Stack), both elevation-of-privilege bugs. SOCRadar reported active exploitation of CVE-2025-25249 (CVSS 9.8) in FortiOS CAPWAP, deploying a Node.js RAT called PivotC2 that exfiltrates Exchange mailboxes to Wasabi cloud storage; 178 devices were compromised out of 30,000 scanned IPs, attributed to a Russian-speaking financially motivated group. Palo Alto disclosed CVE-2026-0310, a 9.2-rated buffer overflow enabling root code execution on PA-Series firewalls, and Fortinet disclosed CVE-2026-84393, a ZTNA certificate validation MITM flaw. Cyera also revealed CVE-2026-6471 ('PostGREShell'), a 12-year-old PostgreSQL logical-decoding flaw allowing code execution via REPLICATION-privileged accounts.

UK Council Attack Linked to Mass Exploitation of SonicWall Flaw

Hunt.io links a UK council attack to mass exploitation of SonicWall SMA1000 flaw CVE-2026-15409 (CVSS 10.0), enabling credential and Active Directory theft.

Hunt.io links, with moderate confidence, the July 17, 2026 attack on the Borough Council of King's Lynn and West Norfolk to mass exploitation of SonicWall SMA1000 appliances via CVE-2026-15409, an unauthenticated SSRF in the WorkPlace portal WebSocket proxy with CVSS 10.0. The operator adapted Rapid7's July 15 PoC into a 50-thread mass scanner within days and stole LDAP credentials for 534 Active Directory accounts across 160 domains, with nine environments losing SAM/LSA secrets and five losing full AD databases via DCSync. CISA added the flaw to its Known Exploited Vulnerabilities catalog and noted use in ransomware campaigns; targeting of ~200,000 Shodan-derived SonicWall addresses spanned government, healthcare, finance, universities, and manufacturing worldwide.

Hackers Chain Chrome and Windows Zero-Days in New BlueMoon Exploit Kit Attacks

Multiple espionage actors, mostly China-nexus, are chaining Chrome V8 and Windows kernel zero-days (CVE-2026-85046, CVE-2026-85880) via the BlueMoon exploit kit against government and defense targets.

Proofpoint identified a new exploit kit dubbed BlueMoon chaining a Chromium V8 type-confusion RCE (CVE-2026-85046), a V8 sandbox escape, and a Windows kernel LPE (CVE-2026-85880). At least four distinct threat clusters, most with suspected China nexus, adopted the kit within days starting with TA412 (Violet Typhoon/APT31) on August 28, 2026. Both Chrome-side flaws were patch-gap zero-days with roughly a four-week exploitation window; the Windows LPE only works on Windows 10 and Server 2019/2022. TA412 used spearphishing posing as university interns to deliver the GemStone browser backdoor disguised as a Google Gemini extension; other clusters delivered ShadowPad via DLL sideloading and a Rust loader against targets in aerospace, government, and finance.
