ReactPress has SQL injection via dynamic column names in TypeORM query builders

ReactPress API list endpoints build TypeORM QueryBuilder conditions using
unsanitized HTTP query parameter names as SQL column identifiers
(e.g. `article.${key}`). TypeORM parameterizes values but not column
names, allowing unauthenticated attackers to inject SQL through crafted
query string keys.

An unauthenticated remote attacker can perform blind SQL injection against
the application database, potentially exfiltrating sensitive data (users,
settings, API keys, article content, etc.).

• GET /api/article
• GET /api/comment
• GET /api/file
• GET /api/page
• GET /api/Knowledge

Vulnerable pattern in findAll() methods, including but not limited to:

• server/src/modules/article/article.service.ts
• server/src/modules/comment/comment.service.ts
• server/src/modules/file/file.service.ts
• server/src/modules/page/page.service.ts
• server/src/modules/knowledge/knowledge.service.ts

• Whitelist allowed filter column names before interpolating into SQL.
• Upgrade to @fecommunity/reactpress >= 3.7.0.
