CVE intelligence and bounded remediation
CVE-2025-62364 — text-generation-webui is an open-source web interface for running Large Language Models
text-generation-webui is an open-source web interface for running Large Language Models. In versions through 3.13, a Local File Inclusion vulnerability exists in the character picture upload feature. An attacker can upload a text file containing a symbolic link to an arbitrary file path. When the application processes the upload, it follows the symbolic link and serves the contents of the targeted file through the web interface. This allows an unauthenticated attacker to read sensitive files on the server, potentially exposing system configurations, credentials, and other confidential information. This vulnerability is fixed in 3.14. No known workarounds exist.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
