CISA Adds Progress Kemp LoadMaster Command Injection Flaw CVE-2026-8037 to KEV Catalog After Confirmed Exploitation
CISA has added the command injection vulnerability CVE-2026-8037 affecting Progress Kemp LoadMaster to its Known Exploited Vulnerabilities catalog following confirmed active exploitation.
The flaw resides in the application delivery controller product from Progress Software. Because input values are not properly sanitized, unauthenticated attackers can execute arbitrary commands on the device. The vulnerability does not require any form of authentication, significantly lowering the barrier for successful attacks.
On August 7, 2026, CISA placed the issue in the KEV list and instructed U.S. federal agencies to complete remediation by August 10, 2026. The agency warned that the flaw is likely to see wider exploitation and that all users should take immediate protective action.
This is not the first time Progress Kemp LoadMaster has been targeted. In 2024 the product was also compromised via CVE-2024-1212, which was likewise added to the KEV catalog after exploitation was observed in the wild.
Security teams are advised to apply vendor patches as soon as they become available and to monitor network traffic for indicators of compromise associated with this vulnerability.

From UDP Probe to Working Tunnel: Analyzing Hysteria2 Behavior via QUIC, HTTP/3 and Client Events
A detailed technical study examined how commercial Hysteria2 VPN endpoints respond to different levels of network probing, starting from simple UDP packets and progressing to full QUIC handshakes and authenticated client connections. The research used custom NetProbe tools on Windows and Linux to test real subscription endpoints, capturing both external probe results and decrypted traffic from an instrumented Hysteria2 client. Simple UDP probes received no response and timed out, while properly formed QUIC Initial packets with TLS ClientHello and ALPN h3 successfully completed handshakes using TLS 1.3 and TLS_AES_256_GCM_SHA384. An unauthenticated HTTP/3 GET request triggered immediate connection closure with H3_NO_ERROR (code 0x100), whereas a legitimate client sending POST /auth with Hysteria-Auth headers received the expected 233 status confirming authentication and UDP forwarding support. Subsequent data transfer tests, including parallel requests and file downloads, were observed inside separate QUIC streams after authentication, confirming that the tunnel carried real traffic. The study highlights differences between external probing and authenticated client behavior, providing practical insight into how Hysteria2 servers handle reconnaissance versus legitimate VPN usage.
Unbound 1.26.1 Patches Critical DNSSEC Validator Flaw CVE-2026-81642 Enabling Remote Code Execution
NLnet Labs has released Unbound 1.26.1 to address CVE-2026-81642, a critical vulnerability in the DNSSEC validator that can cause service crashes and potential remote code execution. The flaw affects all versions up to and including 1.26.0 and is triggered when validating a malicious DNS zone. It resides in the handling of DNSKEY records, where a buffer overflow can occur during DNS response processing. The vulnerability carries a CVSS 4.0 score of 9.1 with a network attack vector, no privileges required, and no user interaction needed. Exploitation requires an attacker to control a malicious DNS zone that the resolver queries, which can lead to denial of service or RCE in the worst case. The update also includes fixes for eight additional security issues, including CVE-2026-82717 and CVE-2026-81634, both involving heap corruption.
BIND DNS Servers Receive Patches for 14 Vulnerabilities Including High-Severity DoS Flaws
The Internet Systems Consortium has released BIND 9 updates that address 14 vulnerabilities across multiple versions of the widely used DNS server software. Seven of the issues received a CVSS score of 7.5 and were rated high severity, while the remaining seven scored between 5.3 and 6.5. The most critical flaw allows an unauthenticated attacker to crash the named process with a single malformed SIG(0) request over DNS over HTTPS. Additional vulnerabilities enable cache poisoning through forged NXDOMAIN responses, downgraded secure delegations, and acceptance of unsigned answers, as well as resource exhaustion via uncontrolled cache growth and excessive CPU consumption. Affected releases span BIND 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, and 9.21.0 through 9.21.25. No workarounds exist, making immediate upgrades to versions 9.20.29, 9.21.26, or 9.20.29-S1 the only mitigation. The ISC reports no known exploitation in the wild and none of the flaws appear in CISA’s Known Exploited Vulnerabilities catalog.
