Pyload-Ng Project: >> Pyload-Ng >> 0.5.0b3.dev34 Security Vulnerabilities
pyLoad is a free and open-source download manager written in Python. From version 0.4.0 to before version 0.5.0b3.dev97, the set_config_value() API endpoint allows users with the non-admin SETTINGS permission to modify any configuration option without restriction. The reconnect.script config option controls a file path that is passed directly to subprocess.run() in the thread manager's reconnect logic. A SETTINGS user can set this to any executable file on the system, achieving Remote Code Execution. The only validation in set_config_value() is a hardcoded check for general.storage_folder — all other security-critical settings including reconnect.script are writable without any allowlist or path restriction. This issue has been patched in version 0.5.0b3.dev97.

pyLoad is a free and open-source download manager written in Python. From version 0.4.20 to before version 0.5.0b3.dev97, the local_check decorator in pyLoad's ClickNLoad feature can be bypassed by any remote attacker through HTTP Host header spoofing. This allows unauthenticated remote users to access localhost-restricted endpoints, enabling them to inject arbitrary downloads, write files to the storage directory, and execute JavaScript code. This issue has been patched in version 0.5.0b3.dev97.

pyLoad is a free and open-source download manager written in Python. Prior to version 0.5.0b3.dev97, a Host Header Spoofing vulnerability in the @local_check decorator allows unauthenticated external attackers to bypass local-only restrictions. This grants access to the Click'N'Load API endpoints, enabling attackers to remotely queue arbitrary downloads, leading to Server-Side Request Forgery (SSRF) and Denial of Service (DoS). This issue has been patched in version 0.5.0b3.dev97.

pyLoad is a free and open-source download manager written in Python. Versions before 0.5.0b3.dev97 are vulnerable to path traversal during password verification of certain encrypted 7z archives (encrypted files with non-encrypted headers), causing arbitrary file deletion outside of the extraction directory. During password verification, pyLoad derives an archive entry name from 7z listing output and treats it as a filesystem path without constraining it to the extraction directory. This issue has been fixed in version 0.5.0b3.dev97.

pyLoad is a free and open-source download manager written in Python. From version 0.5.0b3.dev13 to 0.5.0b3.dev96, the edit_package() function implements insufficient sanitization for the pack_folder parameter. The current protection relies on a single-pass string replacement of "../", which can be bypassed using crafted recursive traversal sequences. This issue has been patched in version 0.5.0b3.dev97.

pyLoad is a free and open-source Download Manager written in pure Python. The `pyload` API allows any API call to be made using GET requests. Since the session cookie is not set to `SameSite: strict`, this opens the library up to severe attack possibilities via a Cross-Site Request Forgery (CSRF) attack. As a result any API call can be made via a CSRF attack by an unauthenticated user. This issue has been addressed in release `0.5.0b3.dev78`. All users are advised to upgrade.
