GHSA-C64Q-HJ4J-375F Yamcs vulnerable to authenticated remote code execution via unescaped StreamSQL `LIKE` pattern compiled by Janino (`LikeExpression`)

Summary Yamcs compiles StreamSQL query expressions to Java at runtime with Janino. The LIKE operator inserts the user-supplied pattern into the generated Java unescaped, inside a "..." literal, so a pattern containing " breaks out and injects arbitrary Java e.g. a static block that runs an OS...

Yamcs is a mission control framework. Prior to 5.12.8 and 5.13.2, Yamcs LikeExpression.fillCodegetValueReturn in yamcs-core/src/main/java/org/yamcs/yarch/streamsql/LikeExpression.java inserts an unescaped LIKE pattern into Java source compiled by Expression.getCompiledExpression through...

GHSA-3G44-3M7X-CGG2 Yamcs vulnerable to authenticated RCE via StreamSQL aggregate-compiler column-name injection in Yamcs `executeSql`

Overview Yamcs compiles StreamSQL expressions to Java on the fly with the Janino SimpleCompiler no restrictive class-loading policy or expression sandbox. When a StreamSQL aggregate such as sum... is applied to a column, the column's name is interpolated unescaped into the generated Java source...

Arbitrary Code Injection

Overview Affected versions of this package are vulnerable to Arbitrary Code Injection in the executeSql process. An attacker can execute arbitrary code with the privileges of the server process by injecting malicious Java code into a column name, which is then compiled and executed by the...

CVE-2026-55511 Yamcs: Authenticated RCE via StreamSQL aggregate-compiler column-name injection in Yamcs `executeSql`

Yamcs is a mission control framework. Prior to 5.12.8 and 5.13.2, Yamcs allows a user with SystemPrivilege.ControlArchiving to create a double-quoted StreamSQL column name that is interpolated into generated Java source by Expression.fillCodeInputDefVars and Expression.sanitizeName. A sum aggrega...

CVE-2026-44632

Yamcs is a mission control framework. Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino...

CVE-2026-44632: Improper Control of Generation of Code

Yamcs is a mission control framework. Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino...

Yamcs Vulnerable to Server-Side Code Injection (RCE) via Janino Expression Engine in `JavaExprAlgorithmExecutionFactory`

Summary A Server-Side Code Injection vulnerability exists in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory. The application dynamically compiles and evaluates user-controlled algorithm text without enforcing a secure sandbox. An authenticated user wi...

CVE-2023-33546

A denial of service vulnerability was found in the janino compiler. If the parser runs on user-supplied input, an attacker could supply content that causes the parser to crash due to a stack overflow...
