Prior to 0.5.0b3.dev101, the API `rpc` function in `api_blueprint.py` handles `multipart/form-data` uploads by reading the whole content of the uploaded file into memory with `file.read()`. This occurs before the data is sent to the underlying function. Since there is no size limit set at this point, a large file upload can exhaust the server's available memory which led to process termination. Version 0.5.0b3.dev101 contains a patch.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-48484)\n\nAffected packages:\n\n- `pyload-ng < 0.5.0b3.dev101`\n\nPatched in:\n\n- `pyload-ng 0.5.0b3.dev101`\n\nSource: https://github.com/advisories/GHSA-vq8p-m3wm-gv5f","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":35.8,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":221194,"id":"CVE-2026-48484","ts":1792030809534,"field":"exploit_available","old":"false","new":"true"}]}
