The below vulnerabilities have been identified by WaterISAC analysts as important for water and wastewater utilities to prioritize in their vulnerability management efforts. WaterISAC shares critical vulnerabilities that affect widely used products and may be under active exploitation. WaterISAC draws additional awareness in alerts and advisories when vulnerabilities are confirmed to be impacting, or have a high likelihood of impacting, water and wastewater utilities. Members are encouraged to regularly review these vulnerabilities, many of which are often included in CISA’s Known Exploited Vulnerabilities (KEV) Catalog.

BerriAI LiteLLM SQL Injection Vulnerability
CVSS v3.1: 9.3
CVE: CVE-2026-42208
Description: LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From version 1.81.16 to before version 1.83.7, a database query used during proxy API key checks mixed the caller-supplied key value into the query text instead of passing it as a separate parameter. An unauthenticated attacker could send a specially crafted Authorization header to any LLM API route (for example POST /chat/completions) and reach this query through the proxy’s error-handling path. An attacker could read data from the proxy’s database and may be able to modify it, leading to unauthorised access to the proxy and the credentials it manages. This issue has been patched in version 1.83.7. CISA has added this vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog.

NGINX Rewrite Heap Overflow Vulnerability
CVSS 4.0: 9.2
CVEs: CVE-2026-42945
Description: NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_rewrite_module module. This vulnerability exists when the rewrite directive is followed by a rewrite, if, or set directive and an unnamed Perl-Compatible Regular Expression (PCRE) capture (for example, $1, $2) with a replacement string that includes a question mark (?). An unauthenticated attacker along with conditions beyond its control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, for systems with Address Space Layout Randomization (ASLR ) disabled, code execution is possible.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Apache ActiveMQ Remote Code Execution Vulnerability
CVSS v3.1: 8.8
CVE: CVE-2026-40466
Description: Improper Input Validation, Improper Control of Generation of Code (‘Code Injection’) vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. An authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP Discovery transport via BrokerView.addNetworkConnector or BrokerView.addConnector through Jolokia if the activemq-http module is on the classpath. A malicious HTTP endpoint can return a VM transport through the HTTP URI which will bypass the validation added in CVE-2026-34197. The attacker can then use the VM transport’s brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring’s ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker’s JVM through bean factory methods such as Runtime.exec(). This issue affects Apache ActiveMQ Broker: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5. Users are recommended to upgrade to version 5.19.6 or 6.2.5, which fixes the issue.

GitHub Enterprise Server Critical Vulnerability
CVSS 3.1: 8.1
CVEs: CVE-2025-8420
Description: Multiple plugins for WordPress by emarket-design with the ’emd-form-builder-lite’ package are vulnerable to Remote Code Execution in various versions via the emd_form_builder_lite_pagenum function. This is due to the plugin not properly validating user input before using it as a function name. This makes it possible for unauthenticated attackers to execute code on the server, however, parameters can not be passed to the functions called.
