A critical flaw in Forminator Forms, a WordPress plugin with more than 600,000 installations, lets unauthenticated attackers upload executable PHP files and take over a site. Tracked as CVE-2026-15748 and scored 9.8, the bug chains weaknesses in the plugin's upload handling: an attacker smuggles a forged record through a Select field that declares itself a file upload, then slips a PHP file past a blocklist that only checks exact extensions. Exploitation requires a form with both a file upload field and a select field, and it affects all versions up to 1.56.1. Because it needs no authentication, automated scanners can hunt for vulnerable sites at scale.
Attackers began exploiting a critical SAP Commerce Cloud flaw within days of its patch, even though no public proof-of-concept exists. Tracked as CVE-2026-58231 and scored 10.0, the improper-authorization bug in the Data Hub Adapter lets an unauthenticated attacker abuse a default authentication client and send crafted input to reach arbitrary code execution. Threat intelligence firm Defused saw the first exploitation attempts hit its honeypots three days after SAP's August patch, classified as automated mass scanning of internet-facing deployments. Shadowserver tracks more than 4,200 exposed SAP Commerce Cloud systems, mostly in Europe and North America. Prior critical SAP flaws have been used by state actors and ransomware crews.
JetBrains patched a critical flaw in TeamCity, its continuous integration and delivery server, that lets an unauthenticated attacker run operating-system commands. Tracked as CVE-2026-63077 and scored 9.8, the deserialization bug affects all on-premises versions and is reached through the agent polling protocol, letting an attacker with HTTP access bypass authentication and execute commands with the privileges of the server process. JetBrains warns that exploitation exposes stored credentials and can compromise the integrity of the build pipeline. It is fixed in versions 2025.11.7 and 2026.1.3, with a patch plugin for older releases, and TeamCity Cloud is already updated. No exploitation has been reported.
Noma Labs found a critical flaw in Ruflo, an open-source platform for orchestrating swarms of AI agents that acts as a harness for coding agents like Claude Code and Codex. Tracked as CVE-2026-59726 and scored 10.0, the flaw is that Ruflo's default Docker deployment exposed its Model Context Protocol bridge to the network with no authentication, offering 233 callable tools. A single unauthenticated request could invoke a shell command tool to run code in the bridge container, read AI provider API keys, steal stored conversations, and poison the platform's persistent agent memory, which can steer future outputs even after the attacker leaves. The flaw is in Ruflo, not in the coding agents.
Security firms ThreatBook and Imperva report attackers targeting a critical flaw in Fastjson, Alibaba's widely used JSON library for Java. On affected Spring Boot applications, a malicious JSON request can execute code without authentication, running with the privileges of the Java process. Tracked as CVE-2026-16723 with an Alibaba-assigned score of 9.0, the confirmed chain needs Fastjson 1.2.68 through 1.2.83, a Spring Boot executable fat-JAR, a network-reachable path that feeds attacker-controlled JSON to the parser, and SafeMode left at its disabled default. Notably, the AutoType feature can stay off and no classpath gadget is required. As of July 25, Alibaba had not shipped a fixed 1.x version.
Cl0p affiliates are exploiting internet-exposed PTC Windchill and FlexPLM product lifecycle platforms through an unauthenticated remote code execution flaw, in a data theft extortion campaign. Product lifecycle management systems track a product from design to retirement and hold computer-aided design files, bills of materials, engineering data, and workflows, making them a concentrated store of intellectual property for manufacturers in automotive, aerospace, defense, medical, and electronics. Cl0p's established pattern is mass exploitation of one enterprise product followed by extortion over stolen data rather than encryption. PTC patched a critical deserialization flaw in the Windchill data management component earlier this year that has already seen exploitation.
Researchers disclosed a critical unauthenticated remote code execution flaw in Hugging Face's LeRobot, the open-source framework used to train and deploy ML models on physical robots. CVE-2026-25874 sits in the framework's web interface, which by default listens on all network interfaces with no authentication - quick for demos, but a hard fail when the demo box ends up on a corporate network. There is no patch yet. Hugging Face has been notified but hasn't released a fix. Particularly serious because LeRobot is usually attached to actual robotic hardware, so a compromise can mean unsafe physical actions.
Wordfence has seen more than 170 live exploit attempts against CVE-2026-3844, a critical unauthenticated arbitrary file upload in the Breeze Cache WordPress plugin from Cloudways. Breeze has roughly 400,000 active installations, making this one of the larger exposure events of the month. The flaw lives in the fetch_gravatar_from_remote function, which fetches avatar images from an arbitrary remote URL and saves them locally without validating the downloaded file's MIME type - so an attacker can point it at a .php payload and drop a webshell directly into a web-accessible directory. The attack is only possible when the 'Host Files Locally - Gravatars' add-on is enabled, which is not the default, but any site that turned it on for performance reasons is wide open. Cloudways shipped the fix as Breeze 2.4.5 earlier this week; as of publication only about 138,000 of the 400,000 installations had downloaded the patched version, leaving hundreds of thousands of sites exposed to a pre-auth RCE with 9.8 CVSS.
