CVE-2002-0802: PostgreSQL

High severity, CVSS 7.5. EPSS: 1.1% chance of exploitation in the next 30 days.

The multibyte support in PostgreSQL 6.5.x with SQL_ASCII encoding consumes an extra character when processing a character that cannot be converted, which could remove an escape character from the query and make the application subject to SQL injection attacks.

Affected products

• PostgreSQL PostgreSQL: version 6.5.0 only
