CVE-2026-45403: AnythingLLM: filesystem-copy-file follows nested symlinks and copies files from outside the allowed directory
Noroxi assessment
Priority: Monitor (action score 10/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.19% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: Mintplex-Labs anything-llm 1.13.0.
Low priority for now. Upgrade to Mintplex-Labs anything-llm 1.13.0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
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, the AnythingLLM agent filesystem copy tool validates only the top-level source and destination paths. The recursive copy helper then descends into child entries using fs.stat() and copies files with fs.copyFile() without validating each child or rejecting symlinks. Because both APIs follow symlinks, a symlink nested inside an allowed source directory can point outside the allowed filesystem root and cause outside file contents to be copied into an allowed destination as a regular file. This vulnerability is fixed in 1.13.0.
