ZDI-26-711: NoMachine Redis Improper Authentication Local Privilege Escalation Vulnerability

ZDI disclosed CVE-2026-92209, an improper authentication flaw in NoMachine's bundled Redis component allowing local privilege escalation (CVSS 7.8).

ZDI published advisory ZDI-26-711 describing an improper authentication vulnerability in the Redis component bundled with NoMachine, tracked as CVE-2026-92209 with CVSS 7.8. A local attacker who can already execute low-privileged code on the target system can escalate privileges. No in-the-wild exploitation or patch details are mentioned in the advisory.

Critical Dell ObjectScale Vulnerabilities Allows Malicious Users to Compromise the Affected system

Dell's DSA-2026-393 fixes ObjectScale/ECS flaws including unauthenticated deserialization RCE CVE-2026-70416 rated CVSS 10.0.

Dell advisory DSA-2026-393 (September 10, 2026) covers multiple flaws in ObjectScale and Elastic Cloud Storage (ECS). CVE-2026-70416 is a critical untrusted-data deserialization RCE (CVSS 10.0) in ObjectScale before 4.4.0.0 allowing unauthenticated remote code execution and full environment takeover, credited to researcher WinD39 (Huynh Dinh Vu). Additional issues include CVE-2025-43936 improper authentication (8.1), CVE-2026-26947 privilege management (6.7), CVE-2026-36591-style weak crypto CVE-2025-36591 (4.4), CVE-2026-76104 permission assignment DoS (5.5), plus third-party CVEs in Apache Log4j, liblzma, and the Linux kernel. Dell advises upgrading to version 4.4.0.0 or later (or 4.2.0.1) and restricting management interfaces until patched.

CVE-2026-85706 | GitLab CE/EE Repository Commits API Path Traversal Vulnerability

GitLab patches CVSS 10.0 path traversal CVE-2026-85706 letting unauthenticated attackers read arbitrary files on self-managed CE/EE servers.

GitLab disclosed CVE-2026-85706, a CVSS 3.1 10.0 path traversal flaw in the repository commits API of self-managed GitLab CE/EE (18.7 before 19.1.8, 19.2 before 19.2.6, 19.3 before 19.3.2), exploitable without authentication to read arbitrary server files. Successful exploitation can expose credentials, tokens, SSH keys, and database credentials accessible to the GitLab process. Fixed versions 19.1.8, 19.2.6, and 19.3.2 were released September 10, 2026; GitLab.com and Dedicated were already patched and no workaround is provided. Horizon3 released a NodeZero Rapid Response test to validate exposure and advises credential rotation for internet-facing instances.

No exploitation was reported, but self-managed administrators are urged to upgrade immediately and review logs for suspicious API and GraphQL activity.

Okta Patches Auth0 and Access Gateway Vulnerabilities Let Attackers Enable XSS, Authentication Bypass and SQL Injection

Okta patches three high-severity flaws in Auth0 AD/LDAP Connector and Access Gateway: stored XSS, auth bypass, SQL injection.

Okta disclosed on September 8, 2026 three vulnerabilities: CVE-2026-85982, a CVSS 9.0 stored XSS in Auth0 AD/LDAP Connector before 8.0.0; CVE-2026-78626, a CVSS 8.1 Protected Rule authorization bypass in Access Gateway before 2026.9.1; and CVE-2026-78623, a CVSS 7.7 SQL injection in Access Gateway advanced-mode datastores. Exploitation requires authenticated access and specific configurations. Fixes require upgrading the connector to 8.0.0+ and Access Gateway to 2026.9.1+.

CVE-2026-73195: Apache Syncope: CSV export spreadsheet formula injection

Apache Syncope CVE-2026-73195 allows authenticated users to inject spreadsheet formulas into CSV exports.

Apache Syncope disclosed CVE-2026-73195, a moderate-rated improper encoding or escaping of output vulnerability. Authenticated users can inject spreadsheet formulas into data that is later exported as CSV, which may execute when an administrator opens the file in a spreadsheet application. The flaw affects syncope-core-provisioning-java in versions 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.7, and 4.1.0-M0 through 4.1.2.

AL26-020 - Vulnerabilities Impacting MikroTik RouterOS - CVE-2026-67276, CVE-2026-67277 and CVE-2026-86060

Canada's Cyber Centre warns of three exploited MikroTik RouterOS vulnerabilities affecting SSH-exposed devices; CISA added two to its KEV catalog.

The Canadian Centre for Cyber Security issued alert AL26-020 for three MikroTik RouterOS vulnerabilities, especially on devices exposing SSH to the internet: CVE-2026-67277 (missing authentication, CWE-306, enabling sensitive information disclosure), CVE-2026-86060 (argument injection, CWE-88, enabling privilege escalation), and CVE-2026-67276 (improper cryptographic signature verification, CWE-347, allowing SSH command channel access without the private key). On September 10, 2026, CISA added CVE-2026-67277 and CVE-2026-86060 to its Known Exploited Vulnerabilities catalog. Fixed versions include RouterOS 6.49.21, 7.23.4 (Long-Term), 7.24.2 (Stable), and 7.25 beta 3.

NCSC Warns of Critical Check Point VPN Flaws as Large-Scale Exploitation Is Expected

Dutch NCSC warns of two critical CVSS 9.8 Check Point VPN flaws enabling unauthenticated remote code execution, urging immediate patching before mass exploitation.

The Dutch NCSC warned that CVE-2026-85102 and CVE-2026-85103, both rated 9.8 CVSS, allow unauthenticated remote attackers to execute arbitrary code on Check Point Quantum Security Gateway, Spark Firewall, and Security Management Server deployments when VPN is enabled. CVE-2026-85102 stems from improper certificate trust validation during VPN negotiation, while CVE-2026-85103 is a heap-based buffer overflow in ASN.1 certificate decoding. Check Point shipped emergency updates on September 9, 2026, including R82.10 Take 44, R82 Take 126, and R81.20 Take 166 or later, plus LivePatch for eligible systems. No public exploit code exists yet, but the NCSC rates exploitation likelihood high and recommends restricting UDP ports 500 and 4500 to known peers as a stopgap.

TP-Link Cameras 0-Day Vulnerabilities Allow Attackers to Spy on Users

Two zero-day flaws in TP-Link Tapo C200 cameras allowed authentication bypass and denial-of-service; fixed in firmware V5_1.4.6.

OPSWAT researchers Khoi Tran and Thai Do found CVE-2026-15315, an authentication bypass in the Tapo C200's local HTTPS interface that lets network-adjacent attackers replay an authentication value to gain administrator access, and CVE-2026-15316, an unauthenticated denial-of-service in the Wi-Fi onboarding process that crashes the camera's HTTPS service. TP-Link was notified on April 16, 2026, confirmed the flaws on July 10, and released patches on August 18, 2026 in firmware V5_1.4.6. Exploitation requires local network access but no valid account, existing session, or user interaction, exposing live feeds and stored recordings to surveillance risk.

AWS Systems Manager Agent Vulnerability Allows Attackers to Bypass Port-Forwarding Restrictions

Critical SSRF flaw in AWS SSM Agent (CVE-2026-89049) lets authenticated users bypass link-local denylists and reach EC2 Instance Metadata Service for IAM credentials.

CVE-2026-89049 (Critical, CVSS v3.1 AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) affects Amazon SSM Agent versions earlier than 3.3.4851.0, with the fix shipping in 3.3.4851.0. The remote-host port-forwarding feature's denylist for link-local addresses can be bypassed because equivalent address representations are not validated, enabling SSRF to restricted endpoints such as the EC2 Instance Metadata Service at 169.254.169.254. An attacker with authenticated AWS access and ssm:StartSession permission could retrieve instance profile IAM credentials and pivot to S3, Secrets Manager, Lambda, or other cloud resources depending on role permissions.
