## What is CVE-2026-40484?

CVE-2026-40484 is a critical vulnerability in ChurchCRM CRM, published on 17 Apr 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the database backup restore functionality extracts uploaded archive contents and copies files from the Images/ directory into the web-accessible document root using recursiveCopyDirectory(), which performs no file extension filtering. An authenticated administrator can upload a crafted backup archive containing a PHP webshell inside the Images/ directory, which is then written to a publicly accessible path and executable via HTTP requests, resulting in remote code execution as the web server user. The restore endpoint also lacks CSRF token validation, enabling exploitation through cross-site request forgery targeting an authenticated administrator. This issue has been fixed in version 7.2.0.

Weakness: CWE-552 (Files or Directories Accessible to External Parties), CWE-434 (Unrestricted Upload of File with Dangerous Type), CWE-269 (Improper Privilege Management)

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.
