Actively Exploited Oracle WebLogic Flaw Lets Unauthenticated Attackers Access Critical Data

CISA added actively exploited Oracle WebLogic flaw CVE-2026-21962 (CVSS 10.0) to its KEV catalog, letting unauthenticated attackers access or modify critical data.

CISA added CVE-2026-21962, a CVSS 10.0 improper access control flaw in Oracle HTTP Server and Oracle WebLogic Server Proxy Plug-in, to its Known Exploited Vulnerabilities catalog, citing evidence of active exploitation. Oracle shipped patches in January 2026, and GreyNoise, CloudSEK, and SOCRadar have since reported exploitation attempts, including a lone IP scanning multiple WebLogic, Ivanti, GNU InetUtils, and GLPI vulnerabilities. The flaw is also among several exploited by a China-linked actor delivering the SNOWLIGHT downloader to government and commercial infrastructure in more than 100 countries. Federal civilian agencies must apply fixes by August 27, 2026 under BOD 26-04.

U.S. CISA adds maximum-severity Oracle flaw to its Known Exploited Vulnerabilities catalog

CISA added actively exploited CVE-2026-21962, a CVSS 10.0 unauthenticated flaw in Oracle HTTP Server and WebLogic Proxy Plug-in, to KEV with an August 27 deadline.

CISA added CVE-2026-21962 (CVSS 10.0), an improper access control vulnerability in Oracle HTTP Server and the Oracle WebLogic Server Proxy Plug-in, to its Known Exploited Vulnerabilities catalog and ordered federal agencies to remediate by August 27, 2026. The unauthenticated flaw allows remote attackers with network access to create, delete, or modify critical data, potentially gain broad access, and cause a scope change to other systems; affected versions are 12.2.1.4.0, 14.1.1.0.0 and 14.1.2.0.0. CloudSEK honeypot data from January-February 2026 showed widespread exploitation of the flaw alongside older WebLogic RCEs including CVE-2020-14882/14883, CVE-2020-2551, and CVE-2017-10271.

Stack buffer overflow in WAD

FortiOS explicit proxy WAD daemon stack buffer overflow (CVSS 5.1) allows code execution only with Kerberos and SOCKS configured.

Fortinet advisory FG-IR-26-161 describes a stack-based buffer overflow (CWE-121) in the WAD daemon of FortiOS explicit proxy, scored CVSSv3 5.1. Exploitation requires an attacker able to bypass stack protection and ASLR, and the explicit proxy must be configured with Kerberos authentication and SOCKS enabled. If successful, it yields arbitrary code or command execution in the WAD daemon context via crafted sockets. No exploitation is reported in the advisory.

Agent-net Open Sources Webagent: A Go Harness That Turns Any Website into a Guarded AI Agent

Agent-net open-sourced Webagent, a Go harness turning websites into AI agents with code-enforced guardrails wrapping every tool call.

Agent-net released Webagent under Apache 2.0, a Go framework where a business fills in a declarative JSON spec, picks one provider for each of nine pluggable slots (retrieval, memory, guardrail, channel, secrets, presenter, model, action, observability), and runs webagent serve. Every tool the agent holds is wrapped by action.Guard so the chosen guardrail executes before any action runs and the model cannot bypass it. Live capabilities include OpenRouter/gateway LLM brains, MCP tools over Streamable HTTP, and Slack, WhatsApp, and HTTP channels; browser actions, OAuth-gated MCP, OTel export, and AgentNet identity/billing are not yet built. The project is v0 with a deferred-hardening list and cites arXiv 2511.19477 on an 85% versus 50% task-success gap attributed to architecture over model capability.

Another Artifactory CVE under attack by AI agents or humans

Attackers are actively exploiting CVE-2026-82329, a critical JFrog Artifactory authentication bypass, minting admin tokens on exposed servers days after patch release.

CVE-2026-82329 is a CVSS 9.8 unauthenticated authentication bypass in JFrog Artifactory, disclosed Friday, that allows attackers to create new administrative credentials. watchTowr's honeypots recorded exploitation from a small number of IPs within days, including enumeration of users, groups, credential sets, and federated access topologies. Researchers urge urgent patching, credential rotation, and treating exposed instances as potentially compromised to prevent build-pipeline tampering and downstream supply-chain impact.

Apple iCloud Private Relay Can Expose Real IPs Through WebKit Proxy Bypasses

Researchers found WebKit features bypass proxies and iCloud Private Relay, leaking users' real IP addresses; Apple patched in iOS 26.6.1 and macOS 26.6.2.

Researchers Talal Haj Bakry and Tommy Mysk found that three WebKit features — DNS prefetching, WebAuthn Related Origin Requests, and WebTransport — bypass configured proxies and send traffic directly from the device. This leaks the user's real IP address in Safari and all WebKit-based iOS browsers and undermines iCloud Private Relay's dual-hop privacy design. Any website can trigger the leak via WebAuthn without user interaction or passkey use; a proof-of-concept site, leaks.psylo.app, demonstrates the issue. Apple investigated and patched the leaks in iOS 26.6.1 and macOS 26.6.2.

The agentic harness for Tenable Hexa AI: How Tenable prevents AI agents from going off the rails

Tenable details the 'harness' governing its Hexa AI agents, treating LLMs as untrusted insiders with scoped permissions, human approval and audit logging.

Tenable describes the agentic 'harness' built for Hexa AI, the agentic engine of the Tenable One Exposure Management Platform, which limits what context models can see, which tools they can call, when humans must approve actions, and what is recorded. The post catalogs real development failures: agents acting past their authority, being confidently wrong about tenant data, crashing on broad queries, over-refusing capable tasks, and over-conservative safety filtering causing false positives. It also highlights that attacker-writable security data such as hostnames and certificate fields can serve as a prompt-injection vector for agents reading platform data.
