CVE-2026-31225
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 · uneditedThe superduper project thru v0.10.0 contains a critical remote code execution vulnerability in its query parsing component. The _parse_op_part() function in query.py uses the unsafe eval() function to dynamically evaluate user-supplied query operands without proper sanitization or restriction. Although the function attempts to limit the execution context by providing a restricted global namespace, it does not block access to dangerous built-in functions. A remote attacker can exploit this by submitting a specially crafted query string containing Python code that imports modules (e.g., os) and executes arbitrary system commands, leading to complete compromise of the server.
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 · high confidenceThe superduper project through v0.10.0 has a remote code execution vulnerability in the _parse_op_part() function in query.py. This function uses Python's unsafe eval() to process user-supplied query operands. Although a restricted global namespace is provided, dangerous built-in functions remain accessible, allowing attackers to import modules like os and execute arbitrary system commands.

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.
-
Identify superduper installation and versionRun 'pip show superduper' or check your requirements.txt/pip freeze output to find the installed version of the superduper packageAffected if The installed version is 0.10.0 or lower, or the version cannot be determined (indicating an unpatched pre-release build)
-
Locate the vulnerable query.py fileSearch for query.py in your superduper installation directory (typically in site-packages/superduper/) and locate the _parse_op_part() functionAffected if The file exists and contains the _parse_op_part() function using eval()
-
Verify eval() usage in _parse_op_part()Inspect the _parse_op_part() function body to confirm it contains eval() calls that process user-supplied operandsAffected if The function contains eval() calls without safe expression parsing (ast.literal_eval or custom parser not present)
-
Check if query parsing feature is enabledReview your application code to see if query operations (search, filter, select with operators) are being used against untrusted inputAffected if Your application accepts user input into query operands that flow through _parse_op_part()
You are affected if superduper version is 0.10.0 or lower AND your application processes user-supplied query operands through the vulnerable _parse_op_part() function.

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 dataReplace eval() with a safe parser such as ast.literal_eval for simple values, or implement a proper expression parser with an explicitly sanitized namespace that blocks dangerous built-ins and module imports.
