⚡ Weekly Recap: WordPress RCE, SonicWall 0-Days, AI Service Attacks, SharePoint 0-Day and More

A single request should not be able to do this much. But this week, small inputs led to code execution, memory loss, stolen keys, and disabled security tools.

The paths were often simple: exposed systems, weak checks, old drivers, fake prompts, and public code used for malware delivery. Some bugs were new. Others were already being used before defenders had time to patch.

Here is the full recap of what broke, what was exploited, and what needs attention now.

⚡ Threat of the Week: New wp2shell WordPress Core Flaw Lets Unauthenticated Attackers Run Code - Searchlight Cyber disclosed a pre-authenticated remote code execution vulnerability in WordPress Core that can be exploited anonymously on a standard WordPress installation, without requiring any plugins or other special conditions. It is a combination of CVE-2026-63030 (REST API batch-route confusion) and CVE-2026-60137 (SQL injection in WordPress core) that can be chained to turn an anonymous request into code execution. watchTowr said it's already seeing proof-of-concept (PoC) exploits in circulation and that it's beginning to see the first signs of in-the-wild exploitation. "This is going to hurt," watchTowr CEO Benjamin Harris said. "WordPress runs on hundreds of millions of websites globally. Some of those will be auto-patched by their hosting providers, but plenty will not, and that is where the damage will be done. Our advice is simple: patch as fast as you possibly can, and do not stop there. Put the controls and investigations in place to determine whether an attacker got there first and to detect and remove any backdoors that may already have been dropped before you patched."

AI Broke Vulnerability Management. Here Is the CISO Case The AI security job market is no longer theoretical. SANS tracked hiring across 10 specific roles and mapped verified job data, salary ranges, and the skills required to get there. The three-tier framework gives your team a clear view of which roles to prioritize now and which to develop toward.

• SonicWall SMA Zero-Days Exploited as 0-Days - A previously undocumented threat actor codenamed UTA0533 has been attributed to the exploitation of recently disclosed SonicWall Secure Mobile Access (SMA) 1000 series VPN appliances as zero-days prior to their public disclosure since June 22, 2026. The discovery was made following an incident response investigation initiated earlier this month. The impacted organization has not been identified. "This threat actor was observed using multiple zero-day exploits, malware designed specifically for SonicWall SMA VPN appliances, as well as other attacker tradecraft," Volexity said. The vulnerabilities in question are CVE-2026-15409 (CVSS score: 10.0) and CVE-2026-15410 (CVSS score: 7.2), both of which could be chained to facilitate arbitrary command execution and take over susceptible devices. Patches for both vulnerabilities were released by SonicWall last week.
• DoS Flaw in OpenSSL - The Okta Red Team disclosed details of HollowByte, a denial-of-service (DoS) flaw in OpenSSL. "By sending a malicious payload of just 11 bytes, a remote, unauthenticated attacker can force a server to allocate disproportionate chunks of memory before any security handshake even begins," Okta said. Put differently, an unauthenticated attacker -- through 11 bytes of carefully crafted data -- can convince OpenSSL to reserve up to 128 KB of heap memory for a handshake message that never actually arrives, causing a server to exhaust available RAM and trigger a DoS condition. The OpenSSL team resolved the issue in versions 4.0.1, 3.6.3, 3.5.7, 3.4.6, and 3.0.21. "Instead of trusting the header outright, OpenSSL now grows the buffer only as bytes actually land on the wire. A claim with no follow-through now costs the server nothing," Okta said.
• CISA Adds New SharePoint RCE Zero-Day to KEV Catalog - The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added a newly patched security flaw impacting Microsoft SharePoint Server to its Known Exploited Vulnerabilities (KEV) catalog, requiring Federal Civilian Executive Branch (FCEB) agencies to apply the fixes by July 19, 2026. The vulnerability, CVE-2026-58644 (CVSS score: 9.8), is a critical deserialization of untrusted data vulnerability that allows an unauthorized attacker to execute arbitrary code. Patches for the flaw have been released as part of the Patch Tuesday updates released on July 14, 2026. Microsoft revised its bulletin to clarify that CVE-2026-58644 has been exploited in the wild, meaning the shortcoming was weaponized as a zero-day prior to the fixes becoming available. The development came as Microsoft shipped its largest Patch Tuesday on record, addressing 622 vulnerabilities.
• OkoBot Malware Framework Infects Windows to Phish Crypto Seed Phrases - A new malware framework called OkoBot is designed to capture the contents of cryptocurrency wallet windows. OkoBot is an updated version of TookPS, which is a downloader for retrieving malicious commands and scripts from attacker-controlled servers to further propagate attacks, including a Python-based infostealer and a remote access trojan called TeviRAT. "This campaign differs from previous activity in that it uses a new framework to deliver all malicious modules and orchestrate them via an SSH tunnel," Kaspersky said. "In total, the framework includes more than 20 malicious payloads and implants, covering a wide variety of functions. At the time of writing, the threat remains active." The infection chain makes use of ClickFix and malware distributed through GitHub that masquerades as legitimate software for initial access. It also comes with a web browser extensions loader to deliver Rilide, a browser-based stealer, as well as inject an implant into Trezor Suite, Ledger Wallet, and Ledger Live processes to collect seed phrases, log keystrokes and clipboard content, take screenshots, and capture keystrokes and the video stream of the target application's window using the OkoSpyware module. Hundreds of victims of the OkoBot campaign have been detected in more than 25 countries, with the highest concentration in Brazil, Vietnam, Canada, Mexico, and Türkiye. The activity remains unattributed.
• NadMesh Scans Exposed AI Services for Cloud Keys and Kubernetes Tokens - A new Go botnet called NadMesh has been observed hunting for exposed AI services related to ComfyUI, Ollama, n8n, Open WebUI, Langflow, and Gradio to steal AWS keys and Kubernetes tokens. "It folds scanning, exploitation, and credential/AI-service intelligence harvesting into a single autonomous platform," QiAnXin XLab said. "On the victim, the bot agent establishes persistence along three independent paths: an SSH public-key backdoor (.ssh/authorized_keys), persistence files in multiple locations (/dev/shm/.a, /var/tmp/.a, /tmp/.a), and hidden cron watchdogs (/etc/cron.d/.sys_monitor, /etc/cron.d/.s)."

🔥 Trending CVEs Bugs drop weekly, and the gap between a patch and an exploit is shrinking fast. These are the heavy hitters for the week: high-severity, widely used, or already being poked at in the wild.

• New Campaign Delivers Remcos RAT - A new malware distribution campaign has abused the credibility of government institutions to increase the likelihood of infection success. The activity targets Indian businesses and taxpayers using Goods and Services Tax (GST)-related themes to distribute malware. "The threat actors impersonated legitimate government departments and distributed malicious emails disguised as official notifications related to taxation, refunds, compliance requirements, and regulatory matters," Seqrite Labs said. "The threat actors employ convincing documents and filenames that closely resemble official GST notifications, making it difficult for recipients to distinguish malicious content from legitimate government correspondence." The end goal is to deploy Remcos RAT and steal sensitive information.
• India's Kudankulam Nuclear Power Plant Suffers a Data Leak - The Kudankulam Nuclear Power Plant located in the Indian state of Tamil Nadu suffered an accidental exposure after Reliance Infra (RPOWER) got hit by a ransomware group called World Leaks, a spin-off of Hunters International, which, in turn, is another variant of the Hive ransomware family. The leak consists of 18,997 files, totalling 14.3GB of data, per security researcher Rakesh Krishnan. They contain purported blueprints for the ventilation and cooling systems used in Unit 3 and Unit 4, along with a complete floor layout of a
