Description

A file upload functionality in Piranha CMS 11.1 allows authenticated remote attackers to upload a crafted PDF file to /manager/media. This PDF can contain malicious JavaScript code, which is executed when a victim user opens or interacts with the PDF in their web browser, leading to a XSS vulnerability.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Piranha. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Remediation status

    No patched version of Piranha has shipped for CVE-2024-55342 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 pinpoints whether CVE-2024-55342 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to CVE-2024-55342. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
