CVE-2026-115322 bytebase CVE debrief

Who should care

Defenders responsible for Bytebase deployments should assess exposure and apply patches. This includes administrators, security teams, and developers using Bytebase in their environments.

Why it matters

CVE-2026-115322 is a medium-severity authorization bypass vulnerability in Bytebase before version 3.16.0. Defenders should assess exposure and apply patches to prevent potential unauthorized access to task runs and logs.

• Potential unauthorized access to task runs and logs
• Possible exposure of sensitive data in task runs and logs
• Need to verify and monitor task runs and logs for suspicious activity
• Requirement to upgrade to Bytebase version 3.16.0 or later to patch the vulnerability

Technical summary

The vulnerability is caused by insufficient authorization checks in the Rollout Service Task Run Handlers in Bytebase before version 3.16.0. Specifically, the GetTaskRunLog, GetTaskRunSession, and PreviewTaskRunRollback functions do not properly validate the task or task run UIDs, allowing authenticated users to access task runs from other projects. This can lead to potential unauthorized access to sensitive data and logs. Defenders should assess exposure and apply patches to prevent potential security incidents. The vulnerability has a medium severity and defenders should prioritize patching to prevent potential security incidents.

Defensive priority

Medium priority for defenders to assess exposure and apply patches

Recommended defensive actions

• Assess exposure by checking if using Bytebase versions before 3.16.0
• Apply patches or upgrade to Bytebase version 3.16.0 or later
• Review task runs and logs for potential unauthorized access
• Monitor for suspicious activity related to task runs and logs
• Perform a detailed review of the task runs and logs to identify potential security incidents
• Verify the effectiveness of compensating controls for exposed systems
• Track exceptions and retest remediated assets to ensure the vulnerability is fully resolved

Evidence notes

The CVE record and source item provide details on the vulnerability, including its description, affected versions, and references to patches and technical descriptions. The vulnerability affects Bytebase before version 3.16.0 and allows authenticated users to access task runs from other projects by supplying foreign task or task run UIDs.
