EPSS

• CVE-2026-45222: 0.15% estimated exploitation activity in the next 30 days; percentile 4.02 (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.

Summarize versions through 0.14.1, fixed in commit 0cfb0fb, creates the daemon configuration directory and file with default filesystem permissions that may be world-readable on Unix-like systems, allowing local attackers to read bearer tokens and API credentials stored in ~/.summarize/daemon.json. A local attacker can exploit these permissive permissions to read the daemon bearer token and persisted provider credentials, enabling unauthorized access to the daemon or recovery of sensitive API keys.

# Patch Next advisory brief: CVE-2026-45222

Advisory: @steipete/summarize allows local attackers to read bearer tokens and API credentials stored in ~/.summarize/daemon.json
IDs: CVE-2026-45222, GHSA-qp7v-gjgg-4mj6
Record: https://patchnext.com/advisories/cve-2026-45222 (revision 3, source checked 26 Oct 2026, 12:52 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @steipete/summarize 0.15.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @steipete/summarize: affected < 0.15.0; fixed in 0.15.0

## Suggested inspection (read-only)
- `npm ls @steipete/summarize --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 @steipete/summarize.
- 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.

## Sources
