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 the repr(Rust) type.

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 before version 0.23.0 contains a memory safety vulnerability related to the repr(Rust) type representation. This could allow memory corruption or potentially remote code execution when processing malicious SQLite queries through the affected library.

MitigationUpgrade rusqlite to version 0.23.0 or later to address the memory safety violation. Review any custom type implementations using repr(Rust) for potential similar issues.

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 installed rusqlite version
    Run 'cargo tree -p rusqlite' or inspect Cargo.lock for the rusqlite entry to find the exact version number
    Affected if The version listed is less than 0.23.0 (e.g., 0.22.0, 0.21.0, etc.)
  2. Check for custom type implementations
    Search project source code for implementations of rusqlite's 'FromSql' or 'ToSql' traits, typically found in type definition blocks
    Affected if Custom Rust types are registered as SQL types using rusqlite's custom type binding features
  3. Verify repr(Rust) attribute usage
    Inspect the custom type definitions for the #[repr(Rust)] attribute, for example: #[repr(Rust)] struct MyType { ... }
    Affected if Custom types used with rusqlite have #[repr(Rust)] defined on them
  4. Check query execution context
    Review code paths that pass user-controlled or untrusted data into rusqlite query methods (execute, query, prepare) with the custom types
    Affected if Untrusted SQL input is processed through rusqlite while using vulnerable custom type representations

You are affected if rusqlite version is below 0.23.0 AND you use custom types with #[repr(Rust)] attribute that handle potentially malicious SQLite query data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
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 to address the memory safety violation. Review any custom type implementations using repr(Rust) for potential similar issues.

Recommended fix High confidence

0.23.0

  1. Update your Cargo.toml file to specify rusqlite version 0.23.0 or later: rusqlite = "0.23.0"
  2. Run `cargo update rusqlite` to update the dependency to the specified version
  3. Run `cargo build` or `cargo test` to verify the upgrade works correctly with your codebase
Caveat Review the changelog between your current version and 0.23.0 for any API changes; minor version bumps in Rust crates may include breaking changes to public APIs
