Arbitrary File Write in Anyquery Server Mode via SQLite ATTACH DATABASE

IdentifiersCVE-2026-50006CWE-73

CVE-2026-50006 is an arbitrary file write vulnerability in Anyquery server mode caused by insufficient restriction of native SQLite disk manipulation capabilities. In the vulnerable configuration, an unauthenticated remote attacker can issue crafted queries that invoke SQLite ATTACH DATABASE behavior to create or write database files at attacker-controlled filesystem locations accessible to the Anyquery process. The issue stems from exposing SQLite functionality without adequately sandboxing or constraining file-backed database operations in the server-side query interface. Release 0.4.5 introduced sandboxing as part of the remediation for this vulnerability.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an unauthenticated network attacker to write arbitrary files anywhere the Anyquery process has sufficient permissions. This can compromise integrity by planting or modifying files, and availability by corrupting application state or consuming storage. In environments where written files can influence execution flow or authentication, the vulnerability may be escalated to remote code execution, including by planting scheduled task definitions, server-executable content, or authentication material.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, restrict or disable SQLite features that permit file-backed database attachment or detachment in server mode. Limit the MySQL-compatible query handler to safe operations only, reduce filesystem permissions of the Anyquery process, prevent write access to sensitive directories, and restrict network exposure of the service to trusted clients or internal interfaces. Avoid running the service with elevated privileges until the fixed version is deployed.

Remediation

Patch, then assume compromise.

Upgrade Anyquery to version 0.4.5 or later, which adds sandboxing to remediate CVE-2026-50006. The vulnerable server-mode query surface should be constrained so native SQLite disk manipulation commands, especially ATTACH DATABASE and related file-backed operations, cannot be used to access arbitrary filesystem paths. Queries should be restricted to safe database contexts such as the main database or controlled in-memory virtual tables, and the service should be reviewed to ensure filesystem access is minimized.
