What is CVE-2026-24770?

CVE-2026-24770 is a critical path traversal vulnerability in infiniflow ragflow, published on 27 Jan 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine. In version 0.23.1 and possibly earlier versions, the MinerU parser contains a "Zip Slip" vulnerability, allowing an attacker to overwrite arbitrary files on the server (leading to Remote Code Execution) via a malicious ZIP archive. The MinerUParser class retrieves and extracts ZIP files from an external source (mineru_server_url). The extraction logic in `_extract_zip_no_root` fails to sanitize filenames within the ZIP archive. Commit 64c75d558e4a17a4a48953b4c201526431d8338f contains a patch for the issue.

Weakness: CWE-22
