CVE-2026-55511

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...

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...

CVE-2026-55565

Yamcs (mission control framework) is vulnerable to authenticated remote code execution in LikeExpression.fillCode_getValueReturn, where an unescaped StreamSQL LIKE pattern is injected into Java source compiled at runtime by Janino (SimpleCompiler.cook). A " in the pattern breaks out of the genera...
