CVE-2023-45561
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue in A-WORLD OIRASE BEER_waiting Line v.13.6.1 allows attackers to send crafted notifications via leakage of the channel access token.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe A-WORLD OIRASE BEER_waiting Line v.13.6.1 application exposes a channel access token that can be obtained by attackers, allowing them to send crafted malicious notifications through the application's notification system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Line application versionOpen the Line application, navigate to Settings > About Line, or check the app version in your device's app manager. The version should be displayed as a number (e.g., 13.6.1).Affected if The installed version is exactly 13.6.1 (Line: = 13.6.1 indicates version 13.6.1 specifically)
-
Audit application source code for hardcoded tokensSearch the application codebase (if you have access) for strings matching channel access token patterns, looking for hardcoded tokens in client-side JavaScript, mobile app code, or configuration files.Affected if A valid Line channel access token is found hardcoded in client-side code or exposed in the application
-
Review API responses for token leakageUse a web proxy or browser developer tools to intercept API responses from the application. Inspect responses for any channel access tokens being returned unexpectedly in JSON or other response bodies.Affected if API responses contain a Line channel access token that should not be exposed to clients
-
Check application logs for token exposureReview server-side or application logs for any entries containing channel access tokens. Search for patterns resembling long alphanumeric strings that serve as Line API authentication tokens.Affected if Channel access tokens are being written to application logs
You are affected if the Line application version is exactly 13.6.1 AND a channel access token is found exposed in client-side code, API responses, or logs.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately rotate the exposed channel access token and audit the application to identify and fix where the token is being leaked (e.g., client-side code, API responses, logs, improper storage).
