namada-apps fixed: 1.1.0 
Upgrade namada-apps to 1.1.0
Verify Direct and Transitive Dependencies

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

How to Check if You Are Affected

To determine whether your application is affected by GHSA-2gw2-qgjg-xh6p, inspect your project dependencies for Namada apps:

inspect dependencies for namada-apps

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-248: Uncaught Exception, where an exception is thrown from a function, but it is not caught. In Namada apps, 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 Ledger crash. A user is able to initialize a post-genesis validator with a negative commission rate using the `--force` flag. If this validator gets into the consensus set, then when computing PoS inflation inside `fn update_rewards_products_and_mint_inflation`, an instance of `mul_floor` will cause the return of an `Err`, which causes `finalize_block` to error. ### Patches This issue has been patched in apps version 1.1.0. The PoS validity predicate now enforces that the commission rate is not negative and any transaction that fails the check will be rejected, both for newly initialized validators and for commission rate change of an existing validator. ### Workarounds There are no workarounds and users are advised to upgrade.
