N-able Issues Fourth N-central Hotfix in Five Weeks for Unauthenticated RCE Flaw

N-able shipped Hotfix 4 for a CVSS 10.0 unauthenticated RCE (CVE-2026-86218) in N-central RMM, with conflicting statements on exploitation.

N-able released 2026.3 Hotfix 4 (build 2026.3.1.14) fixing CVE-2026-86218, a static code injection weakness (CWE-96) scored 10.0 on CVSS 4.0 that enables pre-authentication remote code execution on on-premises N-central RMM servers. Hosted NCOD instances are already patched; N-able's incident notice says the flaw was observed exploited in the wild while its release notes say exploitation is unconfirmed. Huntress, which has tracked N-central attacks since August, advises IP allowlisting, VPN-only access, or taking internet-reachable servers offline until patching. It is the fourth hotfix in five weeks, following fixes for CVE-2026-86206 and CVE-2026-86207, which CISA added to its Known Exploited Vulnerabilities catalog.

CVE-2026-86206, CVE-2026-86207: N-able N-central Authentication Bypass (FIXED)

Rapid7 disclosed two chained N-able N-central flaws, CVE-2026-86206 and CVE-2026-86207, enabling unauthenticated admin account creation; patched in 2026.3 Hotfix 3.

Rapid7 researchers found CVE-2026-86206 (semicolon/Forwarded access-control bypass, CWE-791, CVSSv4 6.9) and CVE-2026-86207 (UserTwoFactorLogin authentication bypass, CWE-305, CVSSv4 7.7) in the latest N-able N-central. Chained, they let a remote unauthenticated attacker create an attacker-controlled System administrator account. The bugs stem from Envoy and Jetty disagreeing on the requested path and whether the client is local. N-able patched both in N-central 2026.3 Hotfix 3, following the earlier CVE-2026-18577 authentication bypass.

N-able Releases Hotfix for Critical Remote Code Execution Vulnerability

N-able shipped Hotfix 4 patching CVE-2026-86218, a CVSS 10.0 pre-authentication RCE in N-central, with no confirmed production exploitation yet.

CVE-2026-86218 is a critical pre-authentication remote code execution flaw in N-able's N-central remote monitoring and management platform, disclosed September 6 with a maximum CVSS score of 10. It affects N-central versions before 2026.3.1.14 and is patched in N-central 2026.3 Hotfix 4. N-able says it has found no evidence of exploitation in production environments. It is the fifth N-able vulnerability disclosed in weeks, following two KEV-listed authentication bypasses and two internal API bypasses.

N-able ships second N-central hotfix as attackers keep exploiting CVE-2026-18577

N-able shipped a second N-central hotfix as attackers actively exploit authentication bypass CVE-2026-18577, attributed to ransomware group Storm-1175.

N-able released Hotfix 2 (N-central 2026.3.1.10) to counter ongoing exploitation of CVE-2026-18577, an authentication bypass that evades the patch for the earlier CVE-2026-18556; exploitation was first detected on August 1, 2026. Post-exploitation includes using the Take Control feature to reach managed endpoints, registering a Cloudflare tunnel service for persistence, creating a 'veeam' domain account, resetting admin passwords, and disabling Microsoft and Sophos security tooling. Microsoft analysts link the activity to Storm-1175, which now deploys a new StormEncryptor ransomware strain instead of Medusa, often reaching data exfiltration and ransomware within days. Sophos and Huntress expanded the IOCs and warned that partners who patched late should treat environments as potentially compromised.

U.S. CISA adds Microsoft Windows, N-able N-central, and Adobe flaws to its Known Exploited Vulnerabilities catalog

CISA added four actively exploited flaws to its KEV catalog: Magento StyleSmuggler RCE, two Windows privilege-escalation bugs, and N-able N-central RCE.

CISA added CVE-2026-75650 (Adobe Commerce/Magento, CVSS 10.0), CVE-2026-81963 and CVE-2026-85880 (Microsoft Windows local privilege escalation, CVSS 7.8 each), and CVE-2026-86218 (N-able N-central pre-auth RCE, CVSS 10.0) to its Known Exploited Vulnerabilities catalog. Sansec researchers report the StyleSmuggler Magento flaw, actively exploited since September 4, lets unauthenticated attackers run code on vulnerable online stores and deploy web shells and backdoors; Microsoft confirmed active exploitation of both Windows flaws, and N-able shipped an emergency hotfix. Federal civilian agencies must patch the Windows flaws by September 22, 2026, and the remaining entries by September 11, 2026 under BOD 22-01.

Risky Bulletin: BEC campaign steals €35 million from French notaries

Hackers stole over €35 million from 500+ French notary offices in a four-year BEC campaign; ANSSI spent two years helping evict the attackers.

A business email compromise campaign breached more than 500 French notary offices — about 7% of all French notaries per the Conseil Supérieur du Notariat — over four years, stealing more than €35 million by phishing initial access and silently modifying wire transfer details. France's cybersecurity agency ANSSI worked for two years behind the scenes to help notaries remove the persistent attackers, who had deep access; officials also feared hackers could issue fake notarized acts such as marriage certificates or forged real estate deals. No forged documents have been found so far, but notaries have added two-factor authentication and in-person requirements for banking details, and banks added extra checks in 2024. The newsletter also notes other incidents, including a $320 million Bitcoin extraction from Blockstream's Liquid Network and a JetBrains Cadence breach via TeamCity servers.

CISA Adds Four Known Exploited Vulnerabilities to Catalog

CISA added four actively exploited vulnerabilities to its KEV catalog, covering Adobe Commerce/Magento, Microsoft Windows, and N-able N-central.

CISA added CVE-2026-75650 (Adobe Commerce and Magento, improper neutralization in a template engine), CVE-2026-81963 (Microsoft Windows link following), CVE-2026-85880 (Microsoft Windows heap-based buffer overflow), and CVE-2026-86218 (N-able N-central static code injection) to the Known Exploited Vulnerabilities Catalog based on evidence of active exploitation. Under Binding Operational Directive 26-04, federal civilian agencies must prioritize rapid remediation of KEV-listed vulnerabilities on exposed assets that grant total control post-exploitation and check for pre-patch compromise. All organizations are encouraged to prioritize these flaws in risk-based patching.

Check Point Patches Critical VPN Vulnerabilities

Check Point patches two critical unauthenticated RCE flaws (CVE-2026-85102, CVE-2026-85103) in VPN gateways and firewalls; no exploitation observed.

Check Point released patches for CVE-2026-85102 and CVE-2026-85103, two critical vulnerabilities (CVSS 9.8) enabling unauthenticated remote code execution in products using VPN functionality. CVE-2026-85102 involves improper validation of certificate data during VPN negotiation, while CVE-2026-85103 is a heap overflow in the VPN certificate ASN.1 decoding flow. Updates cover versions R82.10, R82, and R81.20; manually defining VPN rules is offered as a mitigation, though it does not apply to locally managed Spark Firewall instances. Check Point discovered both flaws internally and reports no evidence of exploitation in the wild.

SAP Patches Critical Extended Passport Processing Vulnerability

SAP patches CVSS 10.0 flaw CVE-2026-44756 (OVERPASS) enabling unauthenticated RCE in S/4HANA and NetWeaver, plus three other criticals; no in-the-wild exploitation reported.

CVE-2026-44756 is a CVSS 10.0 memory corruption flaw in Extended Passport (EPP) deserialization, triggered when a user session opens across web, SAP GUI, and RFC vectors.

More than 200 victims of Medusa ransomware identified over the last year, CISA says

CISA and FBI update Medusa ransomware advisory, reporting more than 500 total victims and warning the gang operationalizes newly disclosed exploits within 24 hours.

CISA and the FBI updated their March 2025 advisory, stating Medusa actors had hit more than 500 victims as of April 2026, up from 300 in 2025, with a focus on healthcare and critical infrastructure. The agencies say Medusa rapidly adopts newly announced exploits, sometimes using them up to a week before public vulnerability disclosure, but does not develop its own zero-days, preferring access obtained from unknown sources. The gang moved to an affiliate model in 2023, offers up to $1 million for exclusive initial access brokers, and uses credential stealers plus legitimate remote access tools including AnyDesk, Atera, ConnectWise and Splashtop. No new victims have appeared on its leak site since April, after the shutdown of the University of Mississippi Medical Center drew significant law enforcement attention.
