## What is CVE-2026-42847?

CVE-2026-42847 is a high-severity SQL injection vulnerability in MacWarrior clipbucket-v5, published on 14 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

ClipBucket v5 is an open source video sharing platform. Prior to 5.5.3 - #122, there is a critical SQL Injection (SQLi) vulnerability in ClipBucket, exploitable through the type parameter on the authenticated admin endpoint admin_area/action_logs.php. The endpoint admin_area/action_logs.php reads $_GET['type'], stores it in $result_array['type'], and forwards it into fetch_action_logs(), where the value is concatenated directly into a SQL WHERE condition on action_type without parameterization. This allows UNION-based SQL injection and direct data exfiltration from the database. This vulnerability is fixed in 5.5.3 - #122.

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

Affected product: MacWarrior clipbucket-v5. 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.
