CVE-2026-35484: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in oobabooga text-generation-webui
text-generation-webui is an open-source web interface for running Large Language Models. Prior to 4.3, an unauthenticated path traversal vulnerability in load_preset() allows reading any .yaml file on the server filesystem. The parsed YAML key-value pairs (including passwords, API keys, connection strings) are returned in the API response. This vulnerability is fixed in 4.3.
AI Analysis
Technical Summary
The oobabooga text-generation-webui prior to version 4.3 contains an unauthenticated path traversal vulnerability in the load_preset() function. This vulnerability allows attackers to specify arbitrary file paths to .yaml files on the server, bypassing intended directory restrictions. The contents of these YAML files, which may include sensitive configuration data such as passwords and API keys, are parsed and returned in API responses, leading to information disclosure. The vulnerability is tracked as CVE-2026-35484 and is categorized under CWE-22. The issue is resolved in version 4.3 of the product.
Potential Impact
Exploitation of this vulnerability can lead to unauthorized disclosure of sensitive information stored in YAML configuration files on the server. This includes credentials and API keys that could be leveraged for further attacks or unauthorized access. The vulnerability does not allow code execution or system availability impact but compromises confidentiality.
Mitigation Recommendations
This vulnerability is fixed in oobabooga text-generation-webui version 4.3. Users should upgrade to version 4.3 or later to remediate this issue. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the vendor advisory, but the fix is stated to be included in version 4.3.
