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 Actively Exploiting Gitea n-day RCE Vulnerability in the Wild to Hijack Instances
Chinese-speaking Red Heron actors mass-exploit Gitea n-day RCE CVE-2026-60004 to steal source code, credentials, and pivot into victim networks.
Acronis Threat Research Unit reports active in-the-wild exploitation of Gitea RCE CVE-2026-60004 (CVSS 9.8, versions 1.17-1.27.0, fixed in 1.27.1) by a Chinese-speaking actor dubbed Red Heron. The actor scanned 1,386 Gitea servers across seven countries, held a separate list of 477 Taiwan-based targets, and confirmed victims in Canada, Argentina, Taiwan, the US, and Sri Lanka. Intrusions deployed the JITTERLY Linux implant with the SIXZUT LD_PRELOAD rootkit, stole password hashes and SSH keys, and in one case gained root admin access to a three-node Proxmox cluster.

Week in review: Linux rootkit deployed on F5 BIG-IP APM devices, Cisco FMC bugs exploited
Weekly roundup: Cisco FMC and N-able N-central zero-days exploited in the wild, MikroTik RouterOS hijacks, Microsoft Patch Tuesday ships two exploited zero-days.
State-sponsored and financially-motivated attackers are actively exploiting CVE-2026-20079, a critical authentication bypass in Cisco Secure Firewall Management Center (FMC), alongside CVE-2026-20316. N-able issued an emergency hotfix for CVE-2026-86218, a critical pre-auth RCE in the N-central RMM platform exploited in the wild. CERT Polska disclosed six RouterOS vulnerabilities being chained to hijack internet-exposed MikroTik devices. Microsoft's September 2026 Patch Tuesday shipped a record patch count including two zero-days, while roughly 67,000 Trezor customers faced phishing after a shipping-partner breach and researchers privately disclosed a zero-click WeChat worm to Tencent.

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.

Langflow Remote Code Execution Vulnerability Exploited in Attacks (CVE-2026-0768)
Critical CVSS 9.8 RCE CVE-2026-0768 in Langflow is under active exploitation, with attackers probing for credentials and secrets.
CVE-2026-0768, a critical (CVSS 9.8) remote code execution flaw in Langflow's code validator, lets attackers execute Python code with root privileges via the validate endpoint's code parameter. VulnCheck honeypots in the UK detected Russian-origin exploitation performing reconnaissance and credential harvesting, querying environment variables like LANGFLOW_SUPERUSER and AWS keys and reading Langflow's secret key. Versions before 1.4.2 are affected; no vendor advisory or public PoC was available at reporting time.
