## What is CVE-2024-39677?

CVE-2024-39677 is a medium-severity SQL injection vulnerability in nhibernate-core, published on 8 Jul 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

NHibernate is an object-relational mapper for the .NET framework. A SQL injection vulnerability exists in some types implementing ILiteralType.ObjectToSQLString. Callers of these methods are exposed to the vulnerability, which includes mappings using inheritance with discriminator values; HQL queries referencing a static field of the application; users of the SqlInsertBuilder and SqlUpdateBuilder utilities, calling their AddColumn overload taking a literal value; and any direct use of the ObjectToSQLString methods for building SQL queries on the user side. This vulnerability is fixed in 5.4.9 and 5.5.2.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command)

What it is: CVE-2024-39677 is a medium-severity SQL injection vulnerability in nhibernate-core, published on 8 Jul 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2024-39677 in the wild and no public exploit code.

Affected packages and fixed versions:
- NHibernate (NuGet): affected all versions; fixed in 5.4.9
- NHibernate (NuGet): affected all versions; fixed in 5.4.9
- NHibernate (NuGet): affected from 5.5.0; fixed in 5.5.2

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
