影響と攻撃シナリオ翻訳中…
Successful exploitation of CVE-2026-4029 allows an attacker to extract sensitive data directly from the WordPress database. This includes user credentials (usernames and passwords, potentially hashed), website configuration details, and any other information stored within the database. The impact is amplified in WordPress Multisite environments, where a single compromise can potentially expose data across multiple sites. The attacker could use this stolen data for further attacks, such as account takeover, privilege escalation, or data breaches. This vulnerability shares similarities with other database access flaws where insufficient authorization leads to unauthorized data extraction.
