CVE-2021-36126 (GCVE-0-2021-36126)

Vulnerability from cvelistv5 – Published: 2021-07-02 13:01 – Updated: 2024-08-04 00:47

Summary

An issue was discovered in the AbuseFilter extension in MediaWiki through 1.36. If the MediaWiki:Abusefilter-blocker message is invalid within the content language, the filter user falls back to the English version, but that English version could also be invalid on a wiki. This would result in a fatal error, and potentially fail to block or restrict a potentially nefarious user.

Severity

No CVSS data available.
