A high-severity persistent cross-site scripting vulnerability affects Johnson Controls Metasys building automation systems (versions 12–15), allowing a low-privilege user to inject a malicious payload via a crafted URL that executes in other users' sessions, including administrators. This could lead to session hijacking and unauthorized access within critical infrastructure environments such as commercial facilities, manufacturing, energy, and government sites. No public exploitation has been reported to CISA at this time, but patches or vendor guidance are available for supported versions.

Johnson Controls Airwall versions 4.0.4 and earlier contain two vulnerabilities: a hard-coded cryptographic key used identically across all deployments, and an arbitrary file read flaw via path traversal. Combined, these could allow an attacker with local access or code/binary access to decrypt sensitive configuration data or read arbitrary files including credential stores and private keys. No public exploitation has been reported, and both flaws require local access or high attack complexity, limiting immediate risk.

CVE-2026-17182 is a critical authentication bypass vulnerability in IBM Db2 Mirror for i affecting versions 7.4, 7.5, and 7.6, allowing remote attackers to bypass authentication controls due to improper validation of request URI path segments. Exploitation could result in unauthorized access, disclosure, or alteration of sensitive database information without requiring credentials. With a CVSS score of 9.8, this vulnerability poses a severe risk to organizations running affected Db2 Mirror deployments.

A critical vulnerability in the getgrav/grav-plugin-api plugin (before 1.0.13) allows an attacker holding a minimal-scope API key to mint a new, unscoped super-access API key by submitting an empty scopes array. This bypasses intended scope restrictions and can be chained with configuration write access to achieve full remote code execution on the underlying Grav CMS instance.

A critical path traversal vulnerability in luci-app-openvpn allows authenticated attackers to write arbitrary files outside the intended upload directory, enabling persistent root-level code execution on OpenWrt-based devices. Exploitation involves planting SSH keys in system directories to maintain access across reboots, making this a severe threat to routers and embedded network infrastructure.

Updated Aug 15, 2026 · CVSS 9.9

A critical vulnerability (CVE-2026-17482) in IBM Documentation Offline versions 1.0.0 through 1.4.1 allows remote attackers to execute arbitrary code due to improper control of file paths. With a CVSS score of 9.8, this flaw is likely exploitable without authentication and poses severe risk to any host running the affected software. Organizations should treat this as an urgent patching priority given the potential for full system compromise.

Updated Aug 15, 2026 · CVSS 9.8

Adobe has released patches for multiple critical vulnerabilities affecting ColdFusion, Commerce, and Campaign Classic, including at least one flaw rated a maximum CVSS score of 10.0. Successful exploitation could allow unauthenticated attackers to achieve arbitrary OS command execution and privilege escalation on affected servers.

Picus Labs' Blue Report 2026 analyzed over 338 million attack simulations across production environments in H1 2026, finding that while perimeter/edge defenses have improved significantly, internal detection and containment capabilities have deteriorated. Attackers are increasingly succeeding not through loud, high-signature attacks but through low-noise techniques that evade internal detection once initial defenses are bypassed.

Threat actors are actively exploiting CVE-2026-55040, a critical SharePoint authentication bypass vulnerability, following the public release of proof-of-concept code. The flaw, patched in Microsoft's July 2026 Patch Tuesday, stems from weak authentication controls and carries a CVSS score of 9.1, allowing attackers to bypass security controls on unpatched SharePoint servers.

An Akira ransomware affiliate compromised a target network and rebooted a system into Safe Mode with Networking to disable endpoint detection and response (EDR) protections. The attacker successfully exfiltrated data but failed to deploy the encryption payload, resulting in a partial (extortion-only) compromise rather than full ransomware impact.
