Insufficient Session Expiration in @cyyynthia/tokenize

GHSA-jcjx-c3j3-44pr

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (@cyyynthia/tokenize 1.1.3), redeploy, then verify what is actually installed.

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 A bug introduced in version 1.1.0 made Tokenize generate faulty tokens with NaN as a generation date. As a result, tokens would not properly expire and remain valid regardless of the lastTokenReset field. Patches Version 1.1.3 contains a patch that'll invalidate these faulty tokens and make new ones behave as expected. Workarounds None. Tokens do not hold the necessary information to perform invalidation anymore.

# Patch Next advisory brief: GHSA-jcjx-c3j3-44pr

Advisory: Insufficient Session Expiration in @cyyynthia/tokenize
IDs: GHSA-jcjx-c3j3-44pr
Record: https://patchnext.com/advisories/ghsa-jcjx-c3j3-44pr (revision 2, source checked 26 Oct 2026, 12:15 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @cyyynthia/tokenize 1.1.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @cyyynthia/tokenize: affected >= 1.1.0, < 1.1.3; fixed in 1.1.3

## Suggested inspection (read-only)
- `npm ls @cyyynthia/tokenize --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 @cyyynthia/tokenize.
- 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.
