Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered in the rusqlite crate before 0.23.0 for Rust. Memory safety can be violated via UnlockNotification.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The rusqlite crate (SQLite bindings for Rust) before version 0.23.0 contains a memory safety vulnerability related to UnlockNotification. This is a critical flaw in a low-level database binding that could allow memory corruption or unsafe memory access, potentially enabling arbitrary code execution.

MitigationUpgrade rusqlite to version 0.23.0 or later. Review the application for any usage of UnlockNotification functionality and ensure the upgrade does not introduce breaking changes.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify rusqlite version in dependencies
    Inspect your Cargo.lock file for the rusqlite entry, or run `cargo tree -p rusqlite` to see the installed version
    Affected if The version listed is less than 0.23.0 (e.g., 0.22.0, 0.21.0, etc.)
  2. Check Cargo.toml for direct rusqlite dependency
    Review your project Cargo.toml for a rusqlite dependency entry and note the specified version range or pinned version
    Affected if The version constraint allows versions below 0.23.0 (e.g., "0.22", ">=0.20.0<0.23.0", or any unpinned "*")
  3. Verify UnlockNotification feature flag usage
    Search Cargo.toml for any enable feature flag referencing unlock_notification (e.g., features = ["unlock_notification"])
    Affected if The unlock_notification feature is enabled in your rusqlite dependency configuration
  4. Detect UnlockNotification API usage in source code
    Search source files for usage of UnlockNotification related APIs such as `unlock_notify`, `SqliteUnlockedNotificationCallback`, or similar patterns
    Affected if Your codebase directly uses UnlockNotification callback functions or related methods

You are affected if your installed rusqlite version is below 0.23.0 and your application either enables the unlock_notification feature or uses UnlockNotification-related API calls.

Upgrade available Upgrade to 0.23.0 or later
Fixed in 0.23.0
Interim mitigation

Upgrade rusqlite to version 0.23.0 or later. Review the application for any usage of UnlockNotification functionality and ensure the upgrade does not introduce breaking changes.

Recommended fix High confidence

0.23.0

  1. Update your Cargo.toml file to specify rusqlite version 0.23.0 or later: Change 'rusqlite = "<0.23.0"' to 'rusqlite = "0.23.0"' or use a semver-compatible requirement like 'rusqlite = ">=0.23.0"'
  2. Run 'cargo update' to fetch the new dependency version
  3. Run 'cargo build' or 'cargo check' to verify the project compiles with the new version
  4. Test your application thoroughly to ensure the upgrade does not introduce regressions
Caveat Minor version upgrades in Rust crates may introduce API changes; review the rusqlite changelog for any breaking changes between your current version and 0.23.0
