CVE-2026-30309
7.8 · HIGHOverview
CVE-2026-30309 is a high-severity vulnerability affecting tokfinity infcode. It was published on March 31, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
InfCode's terminal auto-execution module contains a critical command filtering vulnerability that renders its blacklist security mechanism completely ineffective. The predefined blocklist fails to cover native high-risk commands in Windows PowerShell (such as powershell), and the matching algorithm lacks dynamic semantic parsing unable to recognize string concatenation, variable assignment, or double-quote interpolation in Shell syntax. Malicious commands can bypass interception through simple syntax obfuscation. An attacker can construct a file containing malicious instructions for remote code injection. When a user imports and views such a file in the IDE, the Agent executes dangerous PowerShell commands outside the blacklist without user confirmation, resulting in arbitrary command execution or sensitive data leakage.
Remediation
Check the references section for vendor advisories and patches from tokfinity. Update infcode to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
