CVE-2025-50739
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditediib0011 omni-tools v0.4.0 is vulnerable to remote code execution via unsafe JSON deserialization.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · low confidenceiib0011 omni-tools v0.4.0 contains a remote code execution vulnerability caused by unsafe JSON deserialization. Attackers can exploit this by sending specially crafted JSON payloads that deserialize into malicious objects, leading to arbitrary code execution on the target system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed omni-tools versionRun 'pip show omni-tools' or 'pip list | grep omni-tools' to display the installed version. Alternatively, import the package and print its version attribute if exposed.Affected if The installed version is exactly 0.4.0 or falls within the affected range based on the summary (v0.4.0).
-
Identify JSON deserialization usage in codeSearch source code files for json.loads(), json.load(), pickle.loads(), or other deserialization functions. Review any endpoints or functions that accept JSON input from external sources.Affected if Codebase uses json.loads(), pickle deserialization, or similar functions to process untrusted JSON input.
-
Inspect application entry points and APIsReview API endpoints, web routes, or service entry points that accept JSON payloads. Check if any user-supplied data flows directly into deserialization functions without validation.Affected if Application accepts JSON from network requests and passes it to deserialization functions without sanitization.
-
Review dependency usage and import statementsSearch for 'import omni_tools' or 'from omni_tools' statements in the codebase to identify where the library is used. Check if JSON handling functions from omni-tools are invoked.Affected if The application imports and uses omni-tools library functions that perform JSON deserialization on external input.
You are affected if you are running omni-tools version 0.4.0 and your application uses JSON deserialization on untrusted input without additional validation layers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to a patched version of omni-tools if available; otherwise, restrict network access to the service and implement input validation on all JSON deserialization paths.
