CISA issued an advisory for CVE-2026-6807, an XML External Entity (XXE) vulnerability in the NSA-developed OT and ICS network-mapping tool GrassMarlin. The flaw, tracked as CWE-611 and scored CVSS 5.5, stems from insufficient hardening of XML parsing when the application processes crafted session data, potentially allowing disclosure of sensitive information. GrassMarlin is used in critical infrastructure, industrial control systems, SCADA, and broader IT environments, and CISA said the product is deployed worldwide.
Reporting on the advisory said the issue affects all versions, including version 3.2.1, and that no patch is expected because GrassMarlin reached end-of-life in 2017. Session data is stored in XML files packaged inside .gm3 archives, and a public proof-of-concept from Rapid7 researcher Anna Quinn demonstrated out-of-band exfiltration of arbitrary files through malicious XML content, though practical delivery appears to rely largely on phishing and the bundled Java environment. CISA said it has no evidence of public exploitation targeting this flaw and urged operators to minimize internet exposure, isolate control networks behind firewalls, separate them from business networks, and secure remote access with updated VPNs.

4 events from the most recent confirmed update back to the earliest known activity.
Rapid7 penetration tester Anna Quinn published a public proof-of-concept demonstrating out-of-band exfiltration of arbitrary files from GrassMarlin via malicious XML content. The technique exploited insufficient hardening of XML parsing in session data handling, though practical delivery was described as constrained and likely reliant on phishing.
Because GrassMarlin is no longer maintained, CISA recommended defensive mitigations including minimizing network exposure, isolating control systems behind firewalls, separating them from business networks, and using secure updated VPNs for remote access. The guidance was aimed at organizations using the tool in critical infrastructure, ICS, and SCADA environments.
CISA published advisory ICSA-26-118-01 for CVE-2026-6807, an XML External Entity vulnerability affecting GrassMarlin 3.2.1, with the Register noting all versions are affected. CISA said successful exploitation could disclose sensitive information, assigned a CVSS v3.1 score of 5.5, and reported no known public exploitation targeting the flaw.
The NSA-developed GrassMarlin OT network mapping tool reached end-of-life in 2017, meaning the newly reported vulnerability will not receive a vendor patch. This status shaped later mitigation guidance, which focused on defensive measures rather than remediation through an update.

Public disclosures highlighted multiple high-severity vulnerabilities across industrial control systems, open-source software, and consumer networking gear, with several issues enabling **unauthenticated remote compromise**. Johnson Controls disclosed **CVE-2025-26385** (CVSS 10.0), a critical SQL injection affecting multiple building/ICS management products (including *ADS/ADX, LCS8500, NAE8500, SCT, CCT*) that can allow remote, unauthenticated attackers to execute arbitrary SQL to alter/delete/exfiltrate data; CISA guidance emphasized isolating control system networks from the internet, segmentation, and controlled remote access (e.g., VPNs). Additional unauthenticated remote issues include **CVE-2026-25069** in *SunFounder Pironman Dashboard* (path traversal in log API endpoints enabling arbitrary file read/deletion) and **CVE-2025-51958** in the *DokuWiki* `runcommand` plugin (unauthenticated command execution via `lib/plugins/runcommand/postaction.php`). Other disclosures include developer-tooling and application-layer injection flaws and multiple router memory-corruption bugs with public exploit references. *Orval* fixed **CVE-2026-25141**, a code-injection issue where incomplete escaping can be bypassed using **JSFuck**-style payloads, and *Cybersecurity AI (CAI)* addressed **CVE-2026-25130**, where `subprocess.Popen(..., shell=True)` enables argument/command injection leading to RCE (notably via the `find_file()` tool). Data-layer issues include **CVE-2025-69662** in *geopandas* (`to_postgis()` SQL injection) and **CVE-2026-24854** in *ChurchCRM* (authenticated SQL injection via `PerID` in `/PaddleNumEditor.php`, patched in 6.7.2), while **CVE-2025-36384** affects *IBM Db2 for Windows* (local privilege escalation via unquoted search path). SOHO router flaws **CVE-2026-1686** (*Totolink A3600R*) and **CVE-2026-1637** (*Tenda AC21*) describe remotely reachable buffer/stack overflows with publicly available exploit material, increasing the likelihood of opportunistic exploitation where exposed management interfaces exist.

CISA published multiple Industrial Control Systems (ICS) advisories detailing vulnerabilities across a range of OT and connected-device products, including **critical** issues in *AVEVA Process Optimization* (multiple CVEs) that could enable unauthenticated **remote code execution**, SQL injection, privilege escalation, and sensitive data exposure in affected versions (<=2024.1). Additional advisories describe flaws in several **Siemens** product lines, including a DoS condition in **SIMATIC/SIPLUS ET 200** components triggered via an S7 protocol disconnect request (`CVE-2025-40944`), a TLS certificate upload input-validation issue that can crash/reboot **RUGGEDCOM ROS** devices (`CVE-2025-40935`), a local privilege escalation in **TeleControl Server Basic** prior to V3.1.2.4 (`CVE-2025-40942`), and multiple issues in **SINEC Security Monitor** (including improper authorization in `ssmctl-client` file transfer and report-generation DoS; `CVE-2025-40830`, `CVE-2025-40831`). CISA also noted vulnerabilities affecting **Siemens Industrial Edge** ecosystems, including an authorization bypass in the **Industrial Edge Device Kit** (`CVE-2025-40805`) and authentication enforcement weaknesses on specific API endpoints in **Industrial Edge Devices** that could allow impersonation if an attacker knows a legitimate user identity. Other CISA advisories covered **Schneider Electric EcoStruxure Power Build Rapsody** (`CVE-2025-13844`), where importing a malicious project file (SSD) could trigger memory corruption (e.g., double free/use-after-free) and potentially arbitrary code execution, and **Rockwell Automation FactoryTalk DataMosaix Private Cloud** (`CVE-2025-12807`), where low-privilege users could perform sensitive database operations via exposed API endpoints (SQL injection class). Separately, CISA warned about **YoSmart/YoLink** weaknesses (multiple CVEs) including insufficient authorization controls in the MQTT broker enabling cross-account device control when device IDs are obtained (with IDs described as predictable), plus additional issues such as cleartext transmission and predictable identifiers. A non-CISA item in the set reported Cisco releasing updates for a max-severity **AsyncOS** vulnerability under active exploitation (`CVE-2025-20393`) affecting *Secure Email Gateway* and *Secure Email and Web Manager* appliances, including evidence of attacker-installed persistence and attribution by Cisco Talos to **UAT-9686**; this is a separate enterprise email-security incident and not part of the ICS advisory set.

The Canadian Centre for Cyber Security issued multiple advisories summarizing vendor and CISA disclosures from Feb 9–15, urging organizations to patch widely used platforms. This included **Linux kernel** fixes across supported Ubuntu releases (16.04 through 25.10) and a broad set of **Dell** and **IBM** product updates affecting backup/DR, infrastructure, and automation/transaction systems (e.g., *Dell Avamar/NetWorker/PowerEdge/IDPA/iDRAC Service Module* and *IBM Business Automation Workflow, Operational Decision Manager, Sterling components, webMethods Integration*, and others). CISA also published ICS advisories covering several industrial products with potentially high-impact outcomes. **Siemens Simcenter Femap and Nastran** were reported vulnerable to multiple `NDB`/`XDB` file-parsing issues (CVE-2026-23715 through CVE-2026-23720) that can be triggered via malicious files and may lead to crashes or **arbitrary code execution** (CVSS 7.8), with Siemens recommending upgrades. **GE Vernova Enervista UR Setup** versions `< 8.70` were reported vulnerable to **DLL hijacking** and **path traversal** (CVE-2026-1762, CVE-2026-1763; CVSS 7.8), potentially enabling elevated code execution. Separately, CISA advisory `ICSA-26-043-10` described a **critical** unauthenticated **remote code execution** risk in **Airleader Master** `<= 6.381` due to an unrestricted file upload flaw (CVE-2026-1358; CVSS 9.8); CISA noted no known public exploits at the time and recommended exposure reduction measures such as network segmentation and restricting internet access to control systems.
