Summary

gpt-crawler through 1.5.1 fails to validate the outputFileName parameter in the POST /crawl endpoint, allowing unauthenticated attackers to write arbitrary files to any filesystem path. Attackers can supply absolute paths or parent-directory segments to overwrite existing files with content sourced from attacker-controlled URLs.

Risk Assessment

The risk includes unauthorized overwriting of critical system or application files, potentially leading to server compromise or data integrity violation.

Recommendation

Immediately update gpt-crawler to the latest version that includes a fix for outputFileName validation. Additionally, restrict access to the /crawl endpoint and apply web application firewall rules.
