CVE-2020-27621 (GCVE-0-2020-27621)

Vulnerability from cvelistv5 – Published: 2020-10-22 03:04 – Updated: 2024-08-04 16:18

Summary

The FileImporter extension in MediaWiki through 1.35.0 was not properly attributing various user actions to a specific user's IP address. Instead, for various actions, it would report the IP address of an internal Wikimedia Foundation server by omitting X-Forwarded-For data. This resulted in an inability to properly audit and attribute various user actions performed via the FileImporter extension.

Severity

No CVSS data available.
