More JFrog Artifactory bugs under attack, and all 3 have patches

Multiple attackers are exploiting three JFrog Artifactory CVEs, including critical auth-bypass CVE-2026-82329, to gain admin access and install backdoors.

Wiz confirmed in-the-wild exploitation of all three JFrog Artifactory vulnerabilities: CVE-2026-42018 (high, improper authentication token leak), CVE-2026-42016 (high, privilege escalation), and CVE-2026-82329 (critical, unauthenticated authentication bypass). Starting August 15, attackers chained the first two bugs against self-hosted instances to gain admin access and dropped a custom Rust backdoor for C2; from September 1-8 several attackers exploited CVE-2026-82329. Post-exploitation included persistent admin accounts, Groovy plugins for remote code execution, web shells, token minting, key theft, and reconnaissance. Patching velocity has been slow, with 49-62% of organizations still vulnerable to individual bugs weeks after fixes were released.

IoT Under Siege: The Anatomy of the Latest Mirai Campaign Leveraging Multiple IoT Exploits

Unit 42 tracks a Mirai botnet campaign exploiting over 20 IoT vulnerabilities in routers, cameras and DVRs to build DDoS botnets since March 2023.

Since March 2023, Unit 42 has tracked threat actors exploiting more than 20 IoT vulnerabilities to spread a Mirai botnet variant, first seen downloading payloads from zvub.us on March 14, 2023. Exploited flaws span CVE-2023-1389 (TP-Link Archer), CVE-2022-30525 (Zyxel), CVE-2022-31499 (Nortek) and many router, camera and DVR bugs. The variant decrypts configuration strings with an XOR key derived from 0xDEADBEEF and lacks built-in credential brute forcing, so spreading relies on manual operator exploitation. Two campaigns observed since October 2022 share infrastructure and near-identical samples.

GeoServer Zero-Day Targeted in Active Exploitation Attempts, Can Lead to RCE

A CVSS 9.8 SQL injection zero-day in GeoServer's PostGIS datastore enables RCE and drew active exploitation; fixes shipped in versions 3.0.1, 2.28.5, 2.27.6.

A SQL injection flaw in GeoServer's jsonArrayContains function within the GeoTools PostGIS datastore (GHSA-mqjf-5f49-2fjh, CVSS 9.8) was disclosed August 12, 2026, and saw hundreds of exploitation attempts within hours per watchTowr. An attacker-controlled value is interpolated into a PostgreSQL jsonb_path_exists() expression without escaping; with superuser or pg_execute_server_program privileges it escalates to OS command execution via WFS 1.0. GeoServer released versions 3.0.1, 2.28.5, and 2.27.6, and the flaw is a regression of CVE-2023-25158. GeoServer has a history of mass exploitation, including CVE-2024-36401 used for botnets and proxies.

KATARU, discovered after honeypot Telnet brute-force activity from a Vietnamese IP, downloads an ARM payload (vlxx.arm) and attempts privilege escalation by editing /etc/passwd or exploiting CVE-2026-46300 (Fragnesia), CVE-2026-43284 (Dirty Frag), and CVE-2026-31431 (Copy Fail). It combines Mirai-style TCP, UDP, ICMP, HTTP, QUIC and DNS floods with application attacks against Minecraft, FiveM, OpenVPN and WireGuard. The malware uses X25519 and ChaCha20-Poly1305 encrypted C2, unusually broad persistence across systemd, cron, init frameworks, and Android hooks, plus anti-debugging and decoy traffic to hinder analysis. Implementers copied x86 shellcode into the ARM binary and reused an RFC 7748 test-vector key, indicating low-quality but rapidly evolving commodity development.

New GPUThor Rowhammer Defeats ECC on NVIDIA RTX A6000 to Gain Host Root Access

University of Toronto researchers present GPUThor, a Rowhammer attack that defeats ECC on NVIDIA RTX A4000-A6000 GDDR6 GPUs and achieves host root access.

GPUThor uses non-uniform hammering to bypass Target Row Refresh and overcome SECDED ECC on NVIDIA Ampere workstation GPUs with GDDR6 memory, inducing 72,000 to 377,552 bit flips per gigabyte across RTX A6000, A5000, A4500, and A4000 cards. Triple-bit silent data corruption enables host privilege escalation to root with the IOMMU enabled, reusing GPUBreach page-table corruption techniques, and double-bit DUEs allow escalation when the IOMMU is disabled during a ~10 ms lazy-service window. The attack cut end-to-end escalation time on the A6000 from 21.9 hours to 1.1 minutes. Reported to NVIDIA, Google, Microsoft, and AWS on April 29, 2026; findings were embargoed until August 25, 2026, and no CVE identifier was assigned.

An AI agent contributed significantly across 96 sessions and roughly 80,000 tool calls over 24 active days, though an expert had to steer it and it repeatedly overstepped its threat model. No exploitation of the bypass had been reported as of CISA's July 14 assessment. The RCE affects SharePoint Subscription Edition, 2019, and 2016, plus Project Server 2013 SP1 and Office Web Apps 2013 SP1; the July updates break the chain.
