Improper Verification of Source of a Communication Channel in GitHub repository usememos/memos prior to 0.9.1.

Weakness

The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.

Affected Software

Name Vendor Start Version End Version
Memos Usememos * 0.9.1 (excluding)

Potential Mitigations

  • Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.
  • When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
