CVE-2026-75057 is an information exposure vulnerability in JetBrains IntelliJ IDEA where git credentials are logged in plaintext within IDE log files in versions prior to 2026.1.5. This improper logging practice can lead to unauthorized disclosure of sensitive authentication data if an attacker gains access to the log files. The vulnerability has a CVSS v3.1 base score of 6.2, reflecting medium severity, with an attack vector limited to local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), and no integrity or availability impact (I:N, A:N).

The vulnerability allows exposure of git credentials in plaintext to any user who can read the IDE log files on the affected system. This can lead to unauthorized access to git repositories if the credentials are reused or valid. The impact is limited to confidentiality and requires local access to the logs, with no impact on integrity or availability.

JetBrains has addressed this issue in version 2026.1.5 of IntelliJ IDEA. Users should upgrade to version 2026.1.5 or later to prevent git credentials from being logged in plaintext. No official remediation level or patch link was provided in the source data, but upgrading to the fixed version is the recommended action.
