Summary
pymongo: PYTHON-5994 Use exact match for file ID in GridFS delete methods
Workarounds
Ensure your existing workflow only supports exact matching on the GridFS API.
Impact
When reading/writing via an ID with the GridFS API, require an exact match on the given ID. Otherwise, if a Hash is given in place of the ID, it may be interpreted as criteria, overriding the ID match.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-88029? CVE-2026-88029 is a medium-severity security vulnerability in pymongo (pip), affecting versions <= 4.18.0. It is fixed in 4.18.1.
- Which versions of pymongo are affected by CVE-2026-88029? pymongo (pip) versions <= 4.18.0 is affected.
- Is there a fix for CVE-2026-88029? Yes. CVE-2026-88029 is fixed in 4.18.1. Upgrade to this version or later.
- Is CVE-2026-88029 exploitable, and should I be worried? Whether CVE-2026-88029 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-88029 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
