LowCVSS 2.0Exploitation Probability (EPSS)
Low risk9th percentile - higher than 9% of all known CVEs
Summary
In AnythingLLM prior to version 1.13.0, the agent filesystem copy tool validates only the top-level source and destination paths. The recursive copy helper does not validate each child entry or reject symlinks, allowing bypass of restrictions and copying files from outside the allowed filesystem root.
Risk Assessment
An attacker can exploit this vulnerability to read sensitive system files (e.g., configuration files, passwords) and place them in an accessible location, leading to data leakage and potential application compromise.
Recommendation
Immediately update AnythingLLM to version 1.13.0 or later, which contains the fix for this vulnerability.
Original NVD description (English source)
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.
