CVE-2025-55282: Privilege Escalation in aiven-db-migrate
Platform
postgresql
Component
aiven-db-migrate
Fixed in
1.0.8
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.
Impact and Attack Scenarios
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.
Exploitation Context
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.

What do these metrics mean?
- Attack Vector
- Network — remotely exploitable over the internet. No physical or local access required. Widest attack surface.
- Attack Complexity
- Low — no special conditions required. Attacker can exploit reliably without depending on rare configurations or timing.
- Privileges Required
- High — admin or privileged account required to exploit.
- User Interaction
- None — attack is automatic and silent. Victim does nothing: no click, no file open.
- Scope
- Changed — successful attack can pivot beyond the vulnerable component to other systems or the host OS.
- Confidentiality
- High — complete confidentiality loss. Attacker can read all data: credentials, keys, personal data.
- Integrity
- High — attacker can write, modify, or delete any data: databases, config files, or code.
- Availability
- High — complete crash or resource exhaustion. Full denial of service.

Mitigation and Workarounds
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.
How to fix
Update to aiven-db-migrate version 1.0.7 or higher. This version fixes the privilege escalation vulnerability. The update can be performed through the package manager or by following the instructions provided by Aiven.
