Automated description summarized from trusted sources.
CVE-2026-58025 is a deserialization of untrusted data vulnerability found in Wikimedia Foundation MediaWiki. This flaw is associated with specific program files, including `includes/Import/WikiImporter.Php`, `includes/Import/WikiRevision.Php`, and `includes/Logging/LogEntryBase.Php`. The vulnerability affects MediaWiki versions prior to 1.46.0, 1.45.4, 1.44.6, and 1.43.9. An attacker with `importupload` or `import` permissions (typically the `sysop` group) can exploit this by crafting a malicious XML import file containing serialized PHP objects in the `params` fields. This can lead to arbitrary object instantiation and potentially remote code execution through gadget chains.
