What to do

Vendor response not established. Follow the primary source's mitigation guidance and check back for a fix.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact Any users whom would not desire a traceback to be included in their logs whenever an error is raised in their code will be affected. If users have inadvertently created a scenario in their code that could cause a traceback to include sensitive information and a malicious entity gained access to their log stream, this could create an issue. Patches None yet... users will need to upgrade to 0.4. Workarounds No particularly reasonable ones at present.

# Patch Next advisory brief: GHSA-879p-8gw4-mcpw

Advisory: fgr Vulnerable to Insecure Default Variable Initialization
IDs: GHSA-879p-8gw4-mcpw
Record: https://patchnext.com/advisories/ghsa-879p-8gw4-mcpw (revision 2, source checked 26 Oct 2026, 13:12 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Low (CVSS 3.7)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI fgr: affected <= 0.3.2

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

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on fgr.
- 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.
