  "details" : "### Summary\nThe URL checking logic in PraisonAI has a logical flaw that could be bypassed by attackers, leading to SSRF attacks.\n\n### Details\nThe current PraisonAI project uses _validate_url to validate the input URL. The main logic is to perform security checks on the host portion of the URL extracted by urlparse to prevent SSRF attacks.\n\n<img width=\"1290\" height=\"1145\" alt=\"QQ20260424-151256-24-1\" src=\"https://github.com/user-attachments/assets/d5f16b74-5ad2-444f-8600-b05f78a4b769\" />\n\nHowever, there are indeed differences in parsing between urlparse and the library that actually sends the request. Currently, almost all application scenarios in this project involve first using _validate_url for URL validation, and then using _get_session().get to send the request.\n\n<img width=\"1143\" height=\"740\" alt=\"QQ20260424-151437-24-2\" src=\"https://github.com/user-attachments/assets/b1bf6ec2-d32a-4dac-b814-da819e8d3c83\" />\n\nIn reality, its underlying mechanism is requests.get.\n\n<img width=\"1042\" height=\"576\" alt=\"QQ20260424-151645-24-3\" src=\"https://github.com/user-attachments/assets/e17352c3-4205-44d6-ab6e-75566480215b\" />\n\nThe core issue: `urlparse()` and `requests` disagree on which host a URL like `http://127.0.0.1:6666\\@1.1.1.1` points to:\n\n- `urlparse()` treats `\\` as a regular character and `@` as the userinfo-host delimiter, so it extracts hostname as `1.1.1.1` (public)\n- `requests` treats `\\` as a path character, connecting to `127.0.0.1` (internal)\n\nBelow is a test code I wrote following the code.\n\n```\nimport sys\nfrom pathlib import Path\nfrom pprint import pprint\n\nsys.path.insert(0, str(Path(r\"D:/BaiduNetdiskDownload/PraisonAI-main/PraisonAI-main/src/praisonai-agents\")))\n\nfrom praisonaiagents.tools import spider_tools\n\n# url = \"http://127.0.0.1:6666\\@1.1.1.1\"\nurl = \"http://127.0.0.1:6666\"\n\nresult = spider_tools.scrape_page(url)\n\nif isinstance(result, dict) and \"error\" in result:\n    print(\"scrape failed:\", result[\"error\"])\nelse:\n    pprint(result)\n```\nWhen an attacker uses `http://127.0.0.1:6666/`, the existing detection logic can detect that this is an internal network address and block it.\n\n<img width=\"1068\" height=\"128\" alt=\"QQ20260424-152007-24-4\" src=\"https://github.com/user-attachments/assets/294bff10-2af6-4960-bf69-dbf3340b1e9b\" />\n\nHowever, when an attacker uses `http://127.0.0.1:6666\\@1.1.1.1`, the detection logic resolves the host to `1.1.1.1`, which is a public IP address, thus passing the verification. But in the actual request process, this URL is forwarded by requests.get to `http://127.0.0.1:6666`, bypassing the detection and achieving an SSRF attack.\n\n<img width=\"2089\" height=\"324\" alt=\"QQ20260424-152123-24-5\" src=\"https://github.com/user-attachments/assets/4421ce42-e47b-48de-a97a-56ce56a2bbc9\" />\n\n### PoC\n```\nhttp://127.0.0.1:6666\\@1.1.1.1\n```\n\n### Impact\nSSRF",
