Description

A security vulnerability has been detected in marcopiovanello yt-dlp-web-ui up to v4. This issue affects the function NewGenericDownload of the file server/internal/downloaders/generic.go. Such manipulation of the argument params leads to command injection. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The name of the patch is c7ad3bd79c7c520a7d17e7f2ba19d962be8e7897. A patch should be applied to remediate this issue.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    No patched version of the affected component has shipped for CVE-2026-93371 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-93371 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2026-93371. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
