## What is CVE-2026-4662?

CVE-2026-4662 is a high-severity SQL injection vulnerability in Crocoblock JetEngine, published on 24 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The JetEngine plugin for WordPress is vulnerable to SQL Injection via the `listing_load_more` AJAX action in all versions up to, and including, 3.8.6.1. This is due to the `filtered_query` parameter being excluded from the HMAC signature validation (allowing attacker-controlled input to bypass security checks) combined with the `prepare_where_clause()` method in the SQL Query Builder not sanitizing the `compare` operator before concatenating it into SQL statements. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database, provided the site has a JetEngine Listing Grid with Load More enabled that uses a SQL Query Builder query.

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

Check this codebase for CVE-2026-4662 and fix it if it is affected.

What it is: CVE-2026-4662 is a high-severity SQL injection vulnerability in Crocoblock JetEngine, published on 24 Mar 2026. 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-2026-4662 in the wild and no public exploit code.

Affected product: Crocoblock JetEngine. 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.
