CVE-2026-49367: CWE-862 in JetBrains IntelliJ IDEA
In JetBrains IntelliJ IDEA before 2026.1.1 command execution was possible via the guest user account
AI Analysis
Technical Summary
This vulnerability (CVE-2026-49367) affects JetBrains IntelliJ IDEA versions prior to 2026.1.1 and involves missing authorization controls (CWE-862) that permit command execution through the guest user account. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H) indicates that the vulnerability can be exploited remotely over the network with low attack complexity, requiring low privileges and user interaction, and results in high impact on confidentiality, integrity, and availability. No patch or official remediation level has been disclosed by JetBrains as of the publication date.
Potential Impact
Successful exploitation allows an attacker with guest user access to execute arbitrary commands, potentially leading to full compromise of the affected system's confidentiality, integrity, and availability. This could enable unauthorized access to sensitive data and disruption of services within the IntelliJ IDEA environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict or disable guest user access in IntelliJ IDEA to mitigate the risk of exploitation. Monitor JetBrains advisories for updates regarding patches or official mitigations.
