CVE-2026-48789 — AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting

Medium CVSS 4.3

AnythingLLM is an application that turns pieces of content into context that any LLM can use as references during chatting. Prior to 1.13.0, on Windows, the document folder listing route can accept an encoded absolute Windows path that resolves outside the intended documents directory. The shared path containment helper rejects POSIX-style "../" traversal but does not reject Windows-style parent paths returned by path.relative(), such as "..". This vulnerability is fixed in 1.13.0.

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.
