Incorrect Access Control in Lin-CMS-Flask v0.1.1 allows remote attackers to obtain sensitive information and/or gain privileges due to the application not invalidating a user's authentication token upon logout, which allows for replaying packets.

Security readout for executives and security teams

Plain-English summary

Lin-CMS-Flask v0.1.1 may continue accepting a user authentication token after logout. If someone obtains that token, logout may not stop access, creating a risk of sensitive information exposure or privilege misuse.

Executive priority

Treat this as a targeted product exposure issue, not a broad internet emergency based on current evidence. Prioritize confirmation of Lin-CMS-Flask v0.1.1 usage and vendor fix status.

Technical view

The CVE describes incorrect access control caused by failure to invalidate authentication tokens on logout in Lin-CMS-Flask v0.1.1. The described weakness aligns with CWE-613, Insufficient Session Expiration. No CVSS score, CPE, patch status, or detailed affected inventory is provided in the source bundle.

Likely exposure

Exposure appears limited to deployments using Lin-CMS-Flask v0.1.1. Risk is higher where tokens are long-lived, stored insecurely, logged, shared through intermediaries, or where logout is treated as immediate access revocation.

Exploitation context

The source bundle does not support active exploitation, and the CVE is not listed as KEV. The reported issue is token replay after logout, but no public exploit status or attack complexity details are provided.

Researcher notes

The record lacks CVSS, CPEs, named patch information, and exploitation evidence. The strongest technical signal is the logout token invalidation failure, mapped conceptually to CWE-613 via the referenced weakness definition.

Mitigation direction

  • Check the Lin-CMS-Flask issue and vendor guidance for fixes or upgrade direction.
  • Inventory any Lin-CMS-Flask deployments and identify version v0.1.1 exposure.
  • Review token expiration and logout invalidation behavior in deployed instances.
  • Reduce token lifetime where supported by the application configuration.
  • Rotate potentially exposed credentials or tokens after remediation.

Validation and detection

  • Confirm whether any deployed instance runs Lin-CMS-Flask v0.1.1.
  • Review authentication implementation for server-side token revocation on logout.
  • Audit logs for authenticated activity after recorded logout events.
  • Check whether tokens remain valid beyond intended session termination.
  • Document findings against CWE-613 session expiration expectations.
