## What is CVE-2026-55410?

CVE-2026-55410 is a medium-severity command injection vulnerability in nocobase, published on 15 Jul 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to 2.1.19, NocoBase @nocobase/plugin-backups restored PostgreSQL backups by interpolating the database.schema value from _metadata.json into shell command strings executed with Node.js child_process.exec(), allowing a backup-management user restoring a crafted backup to execute commands as the NocoBase server process. This vulnerability is fixed in 2.1.19.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

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.
