Miggo AIRoot Cause Analysis

The vulnerability involves error messages exposing residual data from reused buffers. The RestClient's error handling mechanism (parseResponseException) is responsible for reading HTTP response content and generating exceptions. In affected versions, this function likely included uncleared buffer data in error messages when parsing malformed queries. The patch in 7.13.4 would address this by ensuring proper buffer sanitization or truncation during error message construction.
