Critical Keycloak Password Reset Flaw Could Let Unauthenticated Attackers Take Over Any Account

Red Hat patched critical Keycloak flaw CVE-2026-18963 (CVSS 9.1) allowing unauthenticated attackers to take over any account, including administrative ones.

Keycloak and Red Hat patched CVE-2026-18963, a CVSS 9.1 flaw (CWE-640) caused by improper state validation in the reset-credentials flow, letting an unauthenticated remote attacker force a password reset without the emailed action token and achieve full account takeover, including admin accounts. Upstream Keycloak 26.7.2 and Red Hat Build of Keycloak 26.4.15/26.6.6 contain fixes; four RHSA errata were issued August 18, 2026. No evidence of exploitation or public exploits exists as of August 24, 2026; mitigation is disabling the Forgot Password feature in all realms.

Critical Flaw in NASA/JPL Open-Source Spacecraft Command Software Allowed Unauthenticated Command Execution

NASA/JPL's AIT-GUI web console (CVSS 9.4) lacked authentication and CSRF protection, letting anyone send unauthenticated commands to spacecraft instruments; fixed in 2.5.2.

Cycode researchers found that AIT-GUI, the browser console of NASA/JPL's open-source AMMOS Instrument Toolkit, ran an HTTP server with no authentication, no session checks, and no CSRF protection on state-changing endpoints, allowing arbitrary commands to spacecraft instruments. The issue combines four weaknesses: binding to 0.0.0.0 regardless of configured host, missing authentication, missing CSRF defense, and path traversal in the /seq and /script/run endpoints. Tracked as GHSA-p9r8-2q67-fp86 with CVSS 9.4, it is fixed in AIT-GUI 2.5.2. The findings came from AI-assisted code analysis confirmed with working proofs-of-concept, including a headless-browser CSRF demonstration.

Elementor Pro Flaw Could Let Unauthenticated Attackers Upload PHP and Execute Code

Patchstack disclosed CVE-2026-32475 (CVSS 9.0), an unauthenticated file-upload flaw in Elementor Pro enabling PHP upload and RCE; fixed in version 4.2.2.

Patchstack researcher Tin Pham reported an unrestricted file upload flaw in Elementor Pro's Forms module (CVE-2026-32475, CVSS 9.0), affecting all versions up to and including 4.2.1. Submitting two file parts for one field bypasses the extension blocklist and writes attacker-controlled PHP into a public uploads directory, yielding unauthenticated remote code execution when a published Elementor page uses a Form widget with a File Upload field. A patched version 4.2.2 shipped August 19, 2026, a day after WordPress 7.0.4 fixed CVE-2026-65640 (CVSS 8.8), an RCE via Postscript file upload when Imagick and Ghostscript are in use.

SAP Commerce Cloud Flaw Could Let Unauthenticated Attackers Execute Arbitrary Code

SAP patched a CVSS 10.0 unauthenticated RCE flaw (CVE-2026-58231) in Commerce Cloud's Data Hub Adapter, plus three critical flaws in NetWeaver and Manufacturing.

SAP's August 2026 updates fix CVE-2026-58231, a CVSS 10.0 flaw in Commerce Cloud's Data Hub Adapter where insufficient authorization checks and input validation let unauthenticated attackers execute arbitrary code. Onapsis urged customers to patch and redeploy, with an IP Filter Set on the vulnerable endpoint offered as a temporary workaround. The update also fixed CVE-2026-44772 (CVSS 9.9) and CVE-2026-44758 (CVSS 9.1), code injection flaws in Manufacturing Integration and Intelligence involving SSRF and SSTI, and CVE-2026-34265 (CVSS 9.8), an out-of-bounds write in NetWeaver ABAP's DIAG protocol parsing that can leak information or crash systems.

Researchers Disclose AI-Assisted SharePoint Exploit Chain Reaching Unauthenticated RCE

Rapid7 disclosed CVE-2026-55040, a SharePoint JWT validation bypass chaining into CVE-2026-63520 unauthenticated RCE, with research substantially AI-agent-assisted; patches released.

Rapid7 disclosed CVE-2026-55040 (CVSS 9.1), several JWT validation pipeline issues letting unauthenticated attackers impersonate chosen SharePoint users by SID or UPN, chained with CVE-2026-63520 (CVSS 8.1), an unsafe .NET type instantiation in Business Connectivity Services yielding RCE as the service account. An AI agent contributed significantly across 96 sessions and roughly 80,000 tool calls over 24 active days, though an expert had to steer it and it repeatedly overstepped its threat model. No exploitation of the bypass had been reported as of CISA's July 14 assessment. The RCE affects SharePoint Subscription Edition, 2019, and 2016, plus Project Server 2013 SP1 and Office Web Apps 2013 SP1; the July updates break the chain.

CVE-2026-82435: Apache Storm Worker: Unauthenticated Remote Memory Exhaustion in the Worker Messaging Decoder

Unauthenticated remote memory exhaustion in Apache Storm Worker 3.0.x Netty decoder fixed in 3.1.0, allowing pre-auth denial of service.

CVE-2026-82435 (rated important) affects Apache Storm Worker (org.apache.storm:storm-client) versions 3.0.0 before 3.1.0. The worker's Netty message decoder sits ahead of SASL authentication handlers and processes frames before any authentication occurs. It allocates buffers sized from an attacker-controlled length field, so a single frame from an unauthenticated peer reaching the worker can exhaust memory. Users must upgrade to 3.1.0.

China-Made ZBT Routers Ship With Two Implants Giving Unauthenticated Attackers Root Access

VulnCheck discloses two factory implants, SPEAKINGSTONE and DARKLANTERN, in ZBT router firmware granting unauthenticated remote attackers root command execution.

VulnCheck found two previously undocumented implants in firmware from Shenzhen Zhibotong Electronics (ZBT), tracked as CVE-2026-74232 (SPEAKINGSTONE) and CVE-2026-74233 (DARKLANTERN), each rated 9.8 on CVSS 3.1. SPEAKINGSTONE (yunmgrd) beacons to a hardcoded C2 over UDP port 10000 and supports root command execution, PPPoE credential exfiltration, DNS hijacking, and reverse SSH tunnels; DARKLANTERN (infosrvd) listens on UDP port 9992 with weak hardcoded authentication. Scanning found 203 internet-facing DARKLANTERN instances across 22 countries, and 392 devices reported to the SPEAKINGSTONE backup C2, nearly all in China on China Mobile. No fixed firmware release is named, and ZBT's white-labeling means model number rather than brand is the reliable detection check.

Tozed ZLT X300 5G CPE firmware 6.01.3 has an unauthenticated TR-069 command injection (CVE-2026-2035703, CVSS 9.8) enabling root code execution.

Tozed ZLT X300 5G CPE router firmware 6.01.3 contains an OS command injection (CWE-78) in the TR-069/CWMP client daemon netcwmpd, tracked as CVE-2026-2035703 with CVSS 9.8. The IPPingDiagnostics Host parameter is passed unsanitized into sprintf, and the resulting shell command executes via system_by_root() as root. An attacker operating a rogue LTE base station built from roughly $300 of SDR hardware can impersonate the carrier's Auto Configuration Server and inject arbitrary commands. The disclosure does not report any observed exploitation.
