CVE-2023-6802 — Github Enterprise Server security vulnerability

High CVSS 7.2

An insertion of sensitive information into the log file in the audit log in GitHub Enterprise Server was identified that could allow an attacker to gain access to the management console. To exploit this, an attacker would need access to the log files for the GitHub Enterprise Server appliance, a backup archive created with GitHub Enterprise Server Backup Utilities, or a service which received streamed logs. This vulnerability affected all versions of GitHub Enterprise Server since 3.8 and was fixed in version 3.8.12, 3.9.7, 3.10.4, and 3.11.1.

Matched remediation archetype

Information disclosure and sensitive data exposure

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace sensitive data through responses, errors, logs, metrics, traces, caches, exports, files, backups, and client bundles.
  • Identify affected subjects, tenants, retention windows, access controls, and downstream copies without opening unnecessary sensitive records.
  • Review metadata, timing, status, length, and existence signals as well as direct content disclosure.

Remediate safely

  • Minimize collection and output, apply field-level authorization and redaction at a centralized boundary, and return generic external errors.
  • Remove secrets and sensitive data from logs, artifacts, URLs, caches, and client-side bundles; rotate credentials that may have been exposed.
  • Update the affected component and add synthetic-data tests for response, error, observability, and export paths.
