Hackers target exposed Vite dev servers to steal AWS, Azure secrets

Mass scanning campaign exploits CVE-2026-39364 in exposed Vite dev servers to steal AWS, Azure, and Terraform credentials.

F5 honeypots detected over 800 attacks and roughly 32,000 events in a month against internet-exposed Vite development servers, abusing CVE-2026-39364 (file access control bypass in Vite 7.1.0-7.3.2 and 8.x before 8.0.5) via parameters like ?raw and ?import&raw. Attackers used extensive wordlists to harvest .env files, AWS/Azure credentials, Terraform state, and /proc/self/environ, with double-encoded traversal to bypass WAFs. The same IPs also leveraged older Vite flaws CVE-2025-30208, actively-exploited CVE-2025-31125, and CVE-2024-45811, primarily from US, Belgium, and Netherlands using Google Cloud ranges.

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.

Hackers Drain $320 Million From Liquid Network, Then Return Most of It

Hackers exploited an Elements bug to drain about 4,000 BTC (~$320M) from Liquid Network's federation wallet, then returned 3,400 BTC after Blockstream patched.

An attacker drained roughly 4,000 of 4,200 BTC (~$320M) from Bitcoin's Liquid Network federation wallet on September 6 by exploiting a bug in Elements, the open-source code powering the sidechain, which allowed unbacked L-BTC tokens that were redeemed for real Bitcoin through SideSwap's authorized peg-out mechanism. The self-described white-hat attackers negotiated publicly via OP_RETURN on-chain messages, demanding the bridge nodes be patched before returning 3,400 BTC (~$262.6M) and keeping about 598 BTC (~$47M). Blockstream confirmed the affected bridge nodes were patched; the network remains paused while federation members complete security work, and experts debate whether the act legally constitutes extortion.

Elementor Pro WordPress Plugin Vulnerability Exploited to Hack Sites

Attackers are actively exploiting critical file-upload flaw CVE-2026-32475 in Elementor Pro, hacking WordPress sites; Defiant has blocked over 190,000 exploit attempts since patching.

Defiant warns that attackers are exploiting CVE-2026-32475 (CVSS 9.8), an unauthenticated arbitrary file upload flaw in the Elementor Pro WordPress plugin's form submission handling, which affects all versions up to 4.2.1 and was patched in version 4.2.2 on August 19. Exploitation began immediately after the fix shipped, with Defiant blocking over 190,000 exploit attempts to date; roughly two-thirds of Elementor's 10 million installations still ran a vulnerable version as of September 4. Successful exploitation writes attacker-controlled PHP files to /wp-content/uploads/elementor/forms/ and can lead to full site compromise; administrators should check that directory for PHP files and review requests to /wp-admin/admin-ajax.php.

BGP Hijack Delivers Malicious Virtualizor Update That Establishes Persistent Root Access

Attackers used a BGP hijack to divert Softaculous traffic and push a malicious Virtualizor update granting root persistence on some hypervisors.

Virtualizor reported that a BGP hijack between August 28 20:57 UTC and August 30 06:10 UTC diverted Softaculous update traffic to an attacker-operated server holding a valid Let's Encrypt certificate. Installations checking for updates during the window could receive a malicious package that added an attacker SSH key to root, created a proxyuser account, and installed a Java payload persisted via a systemd service. Hosting provider AlbaHost confirmed 5 of its 34 Virtualizor hypervisors were root-compromised. Virtualizor shipped Patch 9 with a Security Analyzer on September 1, but cryptographic package signing remains future work.

Exploitation of Sangoma Switchvox flaw is underway (CVE-2026-9586)

Attackers actively exploit SQL injection flaw CVE-2026-9586 in unauthenticated Sangoma Switchvox endpoints, dropping reverse shells and second-stage cryptominer malware.

CVE-2026-9586, an unauthenticated SQL injection in Sangoma Switchvox SMB Edition 8.3, lets crafted HTTP POST requests execute arbitrary SQL against the backend PostgreSQL database. Horizon3 honeypots first saw exploitation on August 30, 2026 from IP 176.65.148.184, and dozens of additional source IPs have since joined with scanning payloads and second-stage malware that appears to be a cryptominer. The flaw was patched in Switchvox 8.4.0.2 on July 14, 2026; roughly 4,000 exposed instances exist, mostly in the United States, and exploitation is likely against most of them.

Cosmos EVM Flaw Exploited After Cosmos Labs Knew Every Blockchain Running It Was Vulnerable

Attackers exploited a critical Cosmos EVM balance bug (GHSA-7g4w-cg88-2cq2) to drain funds from six blockchains; fixed in v0.6.2 and v0.7.2.

Cosmos Labs disclosed that a critical balance-handling flaw in the shared Cosmos EVM module (GHSA-7g4w-cg88-2cq2, no CVE) was exploited to drain funds from six blockchains between August 20 and 25, 2026. The bug, reported April 25 and initially judged harmless, lets vesting accounts delegate more than their spendable balance, wrapping balances to roughly 2^256 and triggering unintended mint/burn in reconciliation, potentially halting chains or burning victims' holdings. Fixes shipped in v0.6.2 and v0.7.2 on August 19 as state-breaking coordinated network upgrades; operators who cannot upgrade must halt their chains. The post-mortem notes the team used public silent patching for a fund-threatening issue, contrary to its own bug bounty policy, and that eleven deployments had never registered with its security channels.
