GHSA-fvcj-hvfw-7f2v — botframework-connector vulnerable to Improper Authentication

2026-10-04T00:06:36.104510+00:00

Affected: npm: botframework-connector

### Impact A maliciously crafted claim may be incorrectly authenticated by the bot. Impacts bots that are not configured to be used as a Skill. This vulnerability requires an attacker to have internal knowledge of the bot.

### Patches The problem has been patched in all affected versions. Please see the list of patched versions for the most appropriate one for your individual case.

### Workarounds Users who do not wish or are not able to upgrade can add an authentication configuration containing ClaimsValidator, which throws an exception if the Claims are Skill Claims.

For detailed instructions, see the link in the References section.
