The chunked upload API (ApiUpload) in MediaWiki before 1.23.11, 1.24.x before 1.24.4, and 1.25.x before 1.25.3 does not restrict the uploaded data to the claimed file size, which allows remote authenticated users to cause a denial of service via a chunk that exceeds the file size.

Security readout for executives and security teams

CVE-2015-8001 affects MediaWiki's chunked upload API. An authenticated remote user could send a chunk larger than the declared file size, consuming resources and causing a denial of service. This is mainly an availability risk for MediaWiki sites that allow user file uploads. Exposure is likely limited to MediaWiki installations running vulnerable versions with chunked uploads reachable by authenticated users. Public or broadly self-service account registration increases practical risk. Prioritize remediation for internet-facing MediaWiki sites that permit uploads, especially those with open registration. Treat as a service availability issue rather than confirmed data theft or remote code execution. Mitigation focus: Upgrade MediaWiki to 1.23.11, 1.24.4, 1.25.3, or later supported releases.; Review the Wikimedia security release announcement for version-specific guidance.; Restrict upload permissions to trusted users until affected systems are updated..
