CISA added a critical flaw in Ray, the open-source framework for scaling AI and machine-learning workloads, to its exploited-vulnerabilities catalog and gave federal agencies just three days to fix it. Tracked as CVE-2025-62593 and scored 9.4, the bug stems from Ray leaving key dashboard and job endpoints unauthenticated; its only browser defense checked that the request's user-agent began with Mozilla, which attackers can forge. Combined with a DNS rebinding attack, a malicious website or advertisement viewed while running Ray can execute code on the developer's machine. A DDoS botnet adopted it before public disclosure, and a separate campaign has been turning unpatched Ray clusters with GPUs into cryptocurrency miners.
Attackers began exploiting a critical unauthenticated flaw in MLflow, the popular open-source machine-learning platform, within hours of its disclosure. Tracked as CVE-2026-64849 and scored 9.3, the server-side request forgery bug lives in the model-registry webhook testing feature: an attacker hosts an endpoint that passes validation, then redirects MLflow to internal targets such as the cloud metadata service or loopback addresses, and MLflow returns their responses. That exposes cloud credentials, API tokens, and secrets. Because MLflow sits close to training data, artifacts, object storage, CI/CD, and inference pipelines, a compromise offers both credentials and a foothold for lateral movement. watchTowr's honeypots saw exploitation attempts almost immediately.
CISA confirmed that ransomware groups are now exploiting a Windows Task Host privilege-escalation flaw that has been flagged as actively exploited since April. Tracked as CVE-2025-60710 and scored 7.8, it is a link-following weakness in the component that runs background scheduled tasks as SYSTEM: a local attacker with only basic user rights can use a junction on a user-writable path to make a SYSTEM-level task act on files it should not, escalating to full control. Microsoft patched it in November 2025, and it affects Windows 11 and Server 2025. Privilege escalation like this is exactly what ransomware operators need to disable defenses and spread after gaining an initial foothold.
GitLab shipped an out-of-band critical patch for a flaw that lets an unauthenticated attacker remotely modify or delete public projects and user data through a GraphQL directive. Tracked as CVE-2026-19478 and scored 9.4, it affects self-managed Community and Enterprise installations; GitLab.com and Dedicated are already fixed. The company released it outside its normal twice-monthly schedule, and the fixed versions are 19.2.4, 19.1.6, 19.0.8, and 18.11.11, with the 18.2 through 18.10 branches left in the affected range and needing an upgrade. A second, lower-severity GraphQL flaw involving cross-site request forgery was fixed in the same release. GitLab reports no known exploitation yet.
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.
Researchers at SSD Secure Disclosure published a two-stage exploit chain that gains full Android kernel access on devices using Unisoc modem firmware, triggered by a VoLTE video call. The first stage, disclosed earlier this year, is remote code execution in the modem via a malformed call; the new second stage abuses a memory-isolation weakness in the modem to disable its protections and reach kernel memory. Pulling it off requires the attacker to run a rogue 4G network and the victim to answer the call. The affected firmware is shared across several Unisoc chipsets used in budget phones from brands like Motorola, Realme, and Xiaomi, and there is no fix from the chipmaker.
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.
The Netherlands cyber agency warned that attackers are exploiting a recently patched macOS flaw to gain root on internet-exposed Macs and install cryptocurrency miners. Tracked as CVE-2026-65400 and scored 9.8, the authentication flaw in the Screen Sharing component lets a network attacker authenticate to the built-in remote desktop service, which uses VNC on port 5900, without valid credentials due to flawed state management. Apple fixed it in emergency updates on August 6 for macOS Tahoe, Sequoia, and Sonoma. Screen Sharing is off by default, but any Mac with it enabled and reachable from the internet is at high risk, and several have already been compromised to run Monero miners.
A newly disclosed zero-day in GeoServer, the widely used open-source geospatial server, is already drawing exploitation attempts, according to watchTowr. The flaw is a SQL injection issue that can lead to remote code execution, and it remains unpatched, with no CVE assigned yet. It was first disclosed publicly by a researcher on August 12, and attackers commonly begin probing internet-facing servers as soon as such details appear. GeoServer instances are frequently exposed to the internet to serve mapping and location data, which makes an unpatched code-execution flaw in the platform an attractive and reachable target. Defenders should treat exposed instances as at risk until a fix ships.
A critical VMware vCenter flaw that Broadcom patched in late July is now under active exploitation in a global campaign. Tracked as CVE-2026-59310 and scored 9.8, it is a directory-traversal bug in the vCenter Syslog server that lets an unauthenticated attacker with network access run code, turning a logging service into a route onto the host. Incident responders at QUIRSO found a single actor exploiting it from around August 3, using path traversal to drop a cron job that launches the open-source reverse_ssh tool for persistent remote access. More than 360 compromised systems across 47 countries have been identified, and patching alone will not remove an existing foothold.
