Splunk Enterprise Discloses 46 Vulnerabilities Including Critical Patroni Authentication Flaw
Splunk has disclosed 46 vulnerabilities in its Splunk Enterprise log analysis platform, including multiple critical and high-severity issues that require immediate attention from administrators.
On 7 October 2026 the vendor released three security advisories covering 17 vulnerabilities in the core product and related applications, five internally identified security problems, and 24 issues in third-party packages.
The most severe finding, tracked as CVE-2026-76268, carries a CVSS v3.1 base score of 9.8 and is rated Critical. It affects the Patroni REST API used for PostgreSQL cluster management inside search head cluster deployments. Because of missing authentication checks, any network-accessible attacker can perform sensitive configuration operations and execute arbitrary operating system commands without credentials.
A second high-severity vulnerability, CVE-2026-76266, was also published. Rated High with a CVSS base score of 7.7, the flaw stems from insufficient privilege handling during package updates on Linux. Under certain conditions it allows an attacker to escalate privileges and run operating system commands as root.
Splunk has made patches available for the affected versions and strongly recommends that customers upgrade without delay. The company continues to monitor for any signs of in-the-wild exploitation of the disclosed issues.

Smart Fish Tank Power Strip Server Breached, Killing Aquarium Fish During National Day Holiday
During China's National Day holiday, the cloud servers of Woda Technology's smart power strips for fish tanks were compromised by malicious hackers, causing widespread remote disconnections and power outages for user devices. The attack left heating rods, oxygen pumps, and circulation systems offline for hours, resulting in the deaths of koi, arowana, and other ornamental fish that users had maintained for years. Woda issued a public notice confirming the intrusion was not a product defect or user error but a deliberate network attack, and the company has since upgraded firewalls, added multi-layer cloud protections, deployed backup servers, and improved local offline logic to prevent future failures. The incident highlights a critical IoT design flaw where devices rely entirely on vendor cloud platforms for control, allowing attackers who breach the server to remotely manage household appliances at scale. Security experts note that the same architecture is used across smart speakers, locks, cameras, and other consumer devices, creating a broad attack surface with minimal updates or segmentation. Woda has reported the case to authorities and preserved logs for forensic investigation.
CISA Adds Five Actively Exploited Vulnerabilities in Apache Struts, BIND, ProFTPD, Strapi and ONLYOFFICE Docs to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added five vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog on October 8, 2026, confirming active exploitation in the wild. The affected products include Apache Struts, BIND, ProFTPD, Strapi, and ONLYOFFICE Docs, with CVEs issued between 2015 and 2023. Federal agencies have until October 11, 2026, to apply mitigations or remove affected systems. One highlighted issue, Strapi CVE-2023-22894, stems from plaintext storage of sensitive information, allowing authenticated attackers to extract user data via query filters. When combined with CVE-2023-22621, the flaws enable remote code execution. CISA also warned that some impacted products may no longer receive vendor support.
FBI Issues Alert on Active FortiBleed Campaign Harvesting Credentials from Exposed FortiGate Firewalls
The FBI and United States Secret Service have issued a joint alert regarding the FortiBleed campaign, an ongoing operation that targets internet-exposed FortiGate firewalls and SSL VPN gateways. Attackers have already collected 86,644 valid credentials from devices across 194 countries as of June 19, demonstrating the global scale of the indiscriminate scanning effort. The campaign relies on reused or previously leaked credentials combined with legacy SHA-256 password storage that enables offline cracking. Operators employ automated credential stuffing, the Go-based FortigateSniffer tool capable of intercepting 24 authentication protocols, and GPU-accelerated password cracking. Once inside, attackers create unauthorized administrator accounts and often delete legitimate ones, forcing victims to perform full device recovery rather than simple password resets. The activity was first documented in June, with the official alert released on October 7, confirming that scanning continues.
Cisco Patches 14 Vulnerabilities in NX-OS Software, Four Rated Critical
Cisco Systems has released security updates addressing 14 vulnerabilities in its Cisco NX-OS Software used in network devices. Four of the seven security advisories published on October 7, 2026, are rated Critical, while three are rated Medium. Several critical issues affect the Cisco Nexus 3000 Series and Nexus 9000 Series switches, impacting features such as NGOAM, MPLS OAM, and the NX-API management interface. Seven vulnerabilities received CVSSv3.1 base scores of 9.0 or higher, with multiple flaws enabling remote code execution as root or denial-of-service conditions. Specific CVEs including CVE-2026-76485, CVE-2026-76486, and CVE-2026-76501 stem from input validation failures in the NGOAM feature and may require SRv6 or NV Overlay configurations to be exploitable. The advisories also cover control plane denial-of-service issues, Python sandbox escapes, and endpoint group contract bypasses in ACI mode.
