Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-89.
Summary
The Duplicator WordPress plugin before 5.1.0 and the duplicator-pro WordPress plugin from 5.0.0 before 5.1.0 are affected. The restore process does not limit its database charset and collation rewrite to schema statements (CWE-89). A Subscriber can store a crafted value in their own profile that breaks out of its string literal and injects SQL into the restore INSERT statement when an administrator restores the backup onto a server lacking one of the source's charsets or collations. The references link to an exploit.

Description from the CNA
The Duplicator WordPress plugin before 5.1.0, duplicator-pro WordPress plugin before 5.1.0 does not restrict its database charset and collation rewrite to schema statements during a restore, so a value a Subscriber stores in their own profile can break out of its string literal and inject SQL into the restore's INSERT statement when an administrator restores the backup onto a server lacking one of the source's charsets or collations.
