1688-product-search

This module primarily implements a legitimate “upload image then search” workflow against a fixed 1688/OpenAPI endpoint, with credentials loaded from environment variables and signed requests. The key security issues are misuse/exposure vectors: it fetches attacker-supplied URLs without allowlisting (SSRF risk) and it can read arbitrary local files from paths provided via image_source (potential local file data exfiltration to the remote API if an attacker can control inputs). Additionally, sys.path manipulation increases import-resolution/supply-chain risk. No strong indicators of intentional malware/backdoor are visible in the provided fragment.
