| عنوان | NousResearch hermes-agent <= v2026.4.23 Improper Authentication (CWE-287) |
|---|
| الوصف | # Technical Details
An Authorization Bypass exists in the `_sync_anthropic_entry_from_credentials_file` method in `agent/credential_pool.py` of hermes-agent.
The application fails to properly isolate multi-tenant credentials during pool rotation when a token encounters a rate limit.
# Vulnerable Code
File: agent/credential_pool.py
Method: _sync_anthropic_entry_from_credentials_file
Why: The method blindly reads the global `~/.claude/.credentials.json` file and overrides individual exhausted pool entries, collapsing distinct accounts into one.
# Reproduction
1. Configure `auth.json` with multiple Anthropic `claude_code` tokens and set a specific token in `~/.claude/.credentials.json`.
2. Induce rate limiting (HTTP 429) for the tokens in the pool to trigger exhaustion and rotation.
3. Observe that `_sync_anthropic_entry_from_credentials_file` overwrites each exhausted token with the contents of the global credentials file.
# Impact
- Breaches isolated authorization boundaries, leading to Information Leakage and Authentication Bypass.
- Completely negates failover and rate-limit bypassing functions. |
