GeoNetwork Fixes Unauthenticated RCE Chain Affecting Government Geoportal Backends

GeoNetwork patched two chained flaws (CVE-2026-63219, CVE-2026-58400) enabling unauthenticated RCE in government geospatial metadata catalogs.

Two flaws in the open-source GeoNetwork catalog chain into unauthenticated RCE: a missing authorization check on the formatter upload endpoint (CVE-2026-63219, CVSS 8.6) and an unsafe Saxon XSLT processor configuration allowing Java execution (CVE-2026-58400, CVSS 9.1). Fixes shipped in versions 4.4.12 and 4.2.17 on July 8, 2026, with details published August 31. Ethiack fingerprinted 121 internet-exposed vulnerable deployments across 39 countries, 89% tied to government or military agencies. No exploitation in the wild or KEV listing was reported at disclosure.

KindaRails2Shell threatens Ruby on Rails apps (CVE-2026-66066)

Critical CVE-2026-66066 in Rails' Active Storage/libvips allows unauthenticated arbitrary file read and possible RCE; active exploitation now observed.

CVE-2026-66066 (KindaRails2Shell), discovered by Ethiack researchers and independently by RyotaK of GMO Flatt Security, lets attackers upload crafted files that exploit libvips' handling of specialty formats to read arbitrary files, including process environment secrets, potentially escalating to RCE. Default Rails 7.0+ setups using Active Storage with the vips processor are affected before versions 7.2.3.2, 8.0.5.1, and 8.1.3.1; fixes shipped July 29, 2026, with VIPS_BLOCK_UNTRUSTED as a partial mitigation. Proof-of-concept exploits circulated after disclosure, and VulnCheck updated that it observed active exploitation originating from a single French IP establishing C2 to a host in Israel. Akamai deployed WAF rules, but experts stress patching and credential rotation over filtering alone.

Parallels Desktop Flaw Lets Non-Admin Mac Users Gain Root, but Intel Macs Can't Install Fix

JFrog disclosed CVE-2026-90894, a 7.8-rated local privilege escalation in Parallels Desktop for Mac, patched only in version 27, which Intel Macs cannot install.

JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 (dubbed ParaShells, CVSS 7.8), a local privilege escalation in Parallels Desktop for Mac that lets non-admin users run code as root. The root-level prl_disp_service listens on a world-writable socket, and argument injection into a tar command via QProcess::splitCommand and the --use-compress-program option yields code execution as root, demonstrated on Parallels Desktop 26.4.0 build 57513 on Apple silicon. The fix appears in version 27.0.0, but Parallels Desktop 27 requires Apple silicon, leaving Intel Macs on the 26.x line with no build JFrog describes as fixed. No exploitation in the wild has been reported and Parallels has not published a statement.

Three CVSS 10.0 ServiceNow Flaws Could Let Unauthenticated Attackers Execute Code and SQL

ServiceNow patched four AI Platform flaws, including three pre-authentication CVSS 10.0 issues enabling unauthenticated code execution, SQL injection, and privilege escalation.

ServiceNow released patches on August 27, 2026 for four AI Platform flaws: CVE-2026-18885 (code injection in the GraphQL Composite Data API), CVE-2026-18886 (improper access control enabling privilege escalation), and CVE-2026-74820 (SQL injection), all self-rated CVSS 10.0 and exploitable without authentication, plus CVE-2026-6876, an 8.7 sandbox escape. Updates were deployed to hosted instances, but self-hosted customers must patch affected Xanadu, Yokohama, Zurich, and Australia release lines themselves. ServiceNow says it is not aware of exploitation of the new flaws, and no public exploit code existed as of August 28, 2026; separately, Defused reported in-the-wild exploitation of the earlier CVE-2026-6875 (CVSS 9.5), later noting the captured payload matched Searchlight Cyber's PoC.

Cisco searched for IOS XR bugs and found so many it rolled them into an update release

Cisco patched three critical flaws, including CVE-2026-20212 unauthenticated remote root code execution in Nexus 9000 switches; no exploitation observed yet.

Cisco disclosed three critical-rated flaws found during a comprehensive internal security review. CVE-2026-20274 and CVE-2026-20279, both CVSS 9.8, affect the IOS XR carrier-grade operating system and are fixed in newly released versions. CVE-2026-20212 lets unauthenticated remote attackers execute code with root privileges on some Nexus 9000 Series Switches by reaching TCP ports 43210 and 43211 in the default Layer 3 VRF; no software fix exists yet, only infrastructure ACL mitigations. Cisco says it has not observed attacks against these flaws.

Cloudflare Workers Spectre Attack Leaks JWT From Co

Researchers demonstrated a remote Spectre attack leaking a JWT between co-located Cloudflare Workers at 12 bits per second, 360x the 2021 rate.

Security researchers showed a remote Spectre attack against Cloudflare Workers that leaked a JWT from a co-located Worker at up to 12 bits per second with 99.16% accuracy, 360 times the 2021 demonstration rate. The attack exploited weaknesses in DyPrIs dynamic process isolation, where long-lived Durable Object invocations could run before isolation and WebSocket-heavy I/O suppressed the branch-misprediction signal. Cloudflare deployed improved DyPrIs, the V8 Sandbox, and MPK-based in-process isolation, and found no indicators of active exploitation over three years.
