CVE-2026-49483Code for IBMi: Uses IBM i components with blind check allowing arbitrary code execution
High 8.9
In plain English
A high-severity incorrect permission assignment in vscode-ibmi from codefori. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.1% (higher than 4% of all known vulnerabilities).
Official description
Code for IBMi is a Visual Studio Code extension for maintaining and compiling ILE languages on the IBMi platform. Prior to 3.0.1, IBMi components implementing IBMiComponent were accepted after checking that a procedure existed without reliably verifying component integrity. Components installed with broad public permissions allow another local account to alter a program such as GETMBRINFO. A later connection can execute the altered program under the connecting account because the LONG_COMMENT marker alone does not establish integrity. This issue is fixed in version 3.0.1.
