github.com/ecies/go/v2 fixed: 2.0.8 
Upgrade github.com/ecies/go/v2 to 2.0.8
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/ecies/go/v2

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-49292, inspect your project dependencies for Github.com/ecies/go/v2:

inspect dependencies for github.com/ecies/go/v2

Analyze the terminal output to locate any version of Github.com/ecies/go/v2 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.8), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Github.com/ecies/go/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If functions `Encapsulate()`, `Decapsulate()` and `ECDH()` could be called by an attacker, he could recover any private key that he interacts with. ### Patches Patched in v2.0.8 ### Workarounds You could manually check public key by calling `IsOnCurve()` function from secp256k1 libraries. ### References https://github.com/ashutosh1206/Crypton/blob/master/Diffie-Hellman-Key-Exchange/Attack-Invalid-Curve-Point/README.md
