EPSS

• CVE-2022-23472: 0.86% estimated exploitation activity in the next 30 days; percentile 58.53 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Impact Everyone below v1.0.5 is impacted by this flaw, of confidentiality being at risk due to the password(s) being easily able to be guessed with Passeo's use of the random library. It is recommended to change any passwords made with Passeo before v1.0.5 and upgrade to v1.0.5, and v1.0.5 patches this with the secrets library. Workarounds No current workaround available than updating to v1.0.5.

# Patch Next advisory brief: CVE-2022-23472

Advisory: Passeo uses insecure random number generator
IDs: CVE-2022-23472, GHSA-mhhf-vgwh-fw9h
Record: https://patchnext.com/advisories/cve-2022-23472 (revision 3, source checked 26 Oct 2026, 13:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 8.2)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: passeo 1.0.5. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI passeo: affected < 1.0.5; fixed in 1.0.5

## Suggested inspection (read-only)
- `python -m pip show passeo`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on passeo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
