Hackers Chain Two New SonicWall Zero-Day Vulnerabilities

SonicWall warns two zero-days (CVE-2026-83548 SSRF, CVE-2026-83549 post-auth RCE) in SMA1000 appliances are being actively exploited.

A September 1 SonicWall advisory discloses actively exploited zero-days in SMA1000 appliance models 6210, 7210 and 8200v, affecting platform-hotfix versions 12.4.3-03453 and 12.5.0-02835 and older. CVE-2026-83548 (CVSS 10.0) is a pre-authentication SSRF in the Appliance Work Place interface via an unintended alternate access path; CVE-2026-83549 (CVSS 7.8) is post-authentication OS command injection enabling RCE in the Appliance Management Console. SonicWall urges hotfix upgrades, IOC checks with SonicWall support, and re-imaging plus credential and TOTP resets if compromise is found.

SonicWall SMA 1000 appliances under attack via zero-day flaws

SonicWall confirms active exploitation of zero-day SSRF (CVE-2026-83548) and command injection (CVE-2026-83549) flaws in SMA 1000 remote access appliances.

SonicWall confirmed attackers are actively exploiting two previously undisclosed vulnerabilities in SMA 1000 SSL VPN appliances, affecting physical and virtual models 6210, 7210, and 8200v but not SMA 100 appliances or SonicWall firewalls. CVE-2026-83548 is a pre-authentication SSRF in the Appliance Work Place interface allowing remote unauthenticated attackers to gain unauthorized access to sensitive functionality, while CVE-2026-83549 is an OS command injection in the Appliance Management Console that can yield remote code execution under specific conditions for authenticated admins. The vendor urged immediate hotfix deployment, IoC review with technical support, and re-imaging or redeployment plus password and TOTP token resets on confirmed compromise. This is the latest in a series of zero-day attacks against SMA 1000 appliances following waves in late 2025 and June-July 2026.

Hackers Mass-Scan Exposed Vite Servers to Steal AWS and Azure Cloud Credentials

F5 honeypots record mass scanning of exposed Vite dev servers exploiting CVE-2026-39364 to harvest AWS and Azure cloud credentials.

F5 honeypots recorded 807 session-grouped attacks and roughly 32,000 raw events in August 2026 against internet-exposed Vite development servers, up from 1,732 events in the previous three months. Scanners abused CVE-2026-39364 (Vite 7.1.0-7.3.1, 8.0.0-8.0.4), bypassing server.fs.deny via @fs routes with ?raw/?import query parameters and double encoding to read .env files, AWS SSO caches, Azure tokens, and Terraform state. The same infrastructure also probed CVE-2025-29927 (Next.js), CVE-2025-30208, CVE-2025-31125 (KEV-listed January 2026), and CVE-2024-45811. Most traffic originated from Google Cloud IP ranges, with the US accounting for 17,297 events.

China-Linked Hackers Chain Chrome Zero-Day With Windows Kernel Flaw in Attacks

Volexity reports China-linked UTA0560 and JungleBamboo chained Chrome zero-day CVE-2026-85046 with kernel flaws to spy on NGOs.

Volexity documented campaigns detected on September 1, 2026, in which China-linked actors UTA0560 and JungleBamboo (APT31) chained CVE-2026-85046 (V8 type confusion), CVE-2026-87491 (WebAssembly sandbox escape), and CVE-2026-85880 (Windows kernel privilege escalation in RtlpCreateServerAcl). Victims were lured via links on legitimate U.S. university sites vulnerable to reflected XSS, then served hidden exploit iframes behind a donation-form image. Although a V8 fix had landed in Chromium's source after private August reporting, Chrome had not yet shipped it, creating a patch gap the actors exploited. The two groups installed distinct payloads: UTA0560 delivered the GRIMWEDGE JScript backdoor via DLL side-loading, while JungleBamboo used the SUPERSTOMP loader to install the LONGTALE credential-stealing Chrome extension disguised as Google Gemini.

Off Guard: Breaking LiteLLM from authentication bypass to cloud compromise

Wiz found LiteLLM auth bypass (CVE-2026-59822) and post-auth RCE (CVE-2026-59821) chainable to cloud compromise; the bypass is in CISA KEV with in-the-wild exploitation.

Wiz scanned roughly 3,074 internet-facing LiteLLM deployments and found 9.6% accepted the default master key sk-1234 or required no authentication, making post-auth attacks effectively pre-auth. The MCP endpoint accepts any Bearer token and grants a valid session (CVE-2026-59822), confirmed exploited in the wild via honeypots and added to CISA's Known Exploited Vulnerabilities catalog. Custom code guardrails allow post-auth root-level RCE via exec(compile(...)) (CVE-2026-59821), while pass-through endpoints lack URL validation, enabling cloud credential theft in post-auth scenarios. All assigned vulnerabilities have been patched; the research was presented at DEF CON 34.
