## What is CVE-2026-96744?

CVE-2026-96744 is a high-severity code injection vulnerability in Laravel MongoDB (PHP), published on 24 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Improper neutralization of special elements in data query logic in the cache lock implementation of the MongoDB integration for Laravel can cause a caller-supplied lock owner value to be evaluated as an aggregation expression rather than as a literal value. An authenticated user who can influence the owner value an application uses when acquiring or restoring a lock may take over or prematurely expire a lock held by another process, which can lead to duplicated or conflicting operations.

Weakness: CWE-943 (Improper Neutralization of Special Elements in Data Query Logic)

Check this codebase for CVE-2026-96744 and fix it if it is affected.

What it is: CVE-2026-96744 is a high-severity code injection vulnerability in Laravel MongoDB (PHP), published on 24 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-96744 in the wild and no public exploit code.

Affected product: Laravel MongoDB (PHP). No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
