CVE-2025-55282 is a privilege escalation vulnerability affecting versions of aiven-db-migrate up to and including 1.0.7. This flaw allows an attacker to gain superuser privileges within PostgreSQL databases during migration processes originating from untrusted servers. The vulnerability stems from a lack of searchpath restriction, enabling the override of pgcatalog and subsequent execution of malicious operators. A fix is available in version 1.0.7.
The impact of CVE-2025-55282 is severe. Successful exploitation allows an attacker to gain complete control over the PostgreSQL database being migrated. This includes the ability to read, modify, and delete data, create new users with elevated privileges, and potentially compromise the entire system. The vulnerability is particularly concerning because it can be exploited during a seemingly benign migration process, making it difficult to detect. An attacker could leverage this to exfiltrate sensitive data, inject malicious code, or disrupt database operations. The blast radius extends to any application or service relying on the compromised PostgreSQL database.
CVE-2025-55282 was publicly disclosed on 2025-08-18. There is no indication of active exploitation campaigns at this time. The vulnerability is not currently listed on the CISA KEV catalog. Public proof-of-concept exploits are not yet available, but the vulnerability's nature suggests a relatively low barrier to exploitation once a suitable PoC is developed.
Organizations utilizing aiven-db-migrate for database migrations, particularly those migrating from untrusted sources or environments with lax security controls, are at significant risk. Environments with legacy PostgreSQL configurations or those lacking robust access controls are also more vulnerable.
• postgresql: Connect to the PostgreSQL database and check the searchpath configuration. An unusual or modified searchpath could indicate exploitation attempts.
SHOW search_path;• linux / server: Monitor PostgreSQL logs for unusual activity during migration processes, specifically looking for errors related to pg_catalog or unexpected operator execution.
journalctl -u postgresql | grep -i "pg_catalog"• generic web: If aiven-db-migrate is exposed via a web interface, monitor access logs for requests related to database migration, particularly those originating from untrusted IP addresses.

The primary mitigation for CVE-2025-55282 is to immediately upgrade aiven-db-migrate to version 1.0.7 or later. If upgrading is not immediately feasible due to compatibility issues or breaking changes, consider temporarily restricting migrations from untrusted sources. Implement strict access controls and monitoring of database migration processes. Review and audit existing migration scripts for any potential vulnerabilities. While a WAF or proxy cannot directly prevent this vulnerability, they can help detect and block suspicious migration attempts. After upgrading, confirm the fix by attempting a migration from a trusted source and verifying that no superuser privileges are granted during the process.
