## What is CVE-2026-81662?

CVE-2026-81662 is a high-severity code injection vulnerability in flowintel, published on 27 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

Affected versions of Flowintel improperly trust configuration keys supplied to the alerts settings update endpoint. While configuration values were normalized to Python literals, the corresponding keys were used directly when constructing and replacing lines in conf/config_module.py.

The vulnerable code used requester-controlled keys in both the regular expression and the generated assignment:

f'{key} = {py_val}'

and appended an assignment if the key was not already present. The modified Python configuration module was subsequently reloaded using importlib.reload(). This creates a code-generation boundary in which specially crafted configuration keys can alter the Python source structure and result in execution of attacker-controlled Python statements. 

Version impacted >=3.3.0

Weakness: CWE-94 (Improper Control of Generation of Code), CWE-20 (Improper Input Validation)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-81662 and fix it if it is affected.

What it is: CVE-2026-81662 is a high-severity code injection vulnerability in flowintel, published on 27 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-81662 in the wild and no public exploit code.

Affected product: flowintel. No package-level version data is available, so check the vendor advisory linked from the reference page.

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.
