(https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlparse)\n\nFor example, When an unusual URL like `https:///example.com` is entered, `urlparse` interprets it as a relative path, but in the actual request it is converted to `https://example.com` due to url normalization.\n\n### PoC\n1. In the next variable, insert the URL to which you want to redirect the user.\n![301715949-bb1451eb-5e84-451d-83b4-5c3e204d1df7](https://github.com/pyload/pyload/assets/114328108/6fe639ea-1f85-4715-bf6c-c9c8c4ee9c94)\n\n\n\n2. Check that it is possible to bypass url validation and redirect users to an arbitrary url.\n![301715824-3de6584a-878d-4ec4-a3d5-a34d11c6c0ac](https://github.com/pyload/pyload/assets/114328108/902b3244-a4ef-4f8e-8319-c4b92764f15f)\n![301716107-ba5ab7b9-7aa8-4b7a-8924-eba82442b4c3](https://github.com/pyload/pyload/assets/114328108/35191d7b-50b9-4a46-8319-ebdebec20b41)\n\n\n\n### Impact\nAn attacker can use this vulnerability to redirect users to malicious websites, which can be used for phishing and similar attacks.\n\n\n## Affected packages\n\n- `pyload-ng < 0.5.0b3.dev79`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `pyload-ng 0.5.0b3.dev79`","depth":"sunlit","depthScore":34,"depthScoreParts":{"impact":33.6,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
