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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-20","CWE-400"],"references":["https://github.com/pyload/pyload/blob/8e447958b8a66c5899775e725a8b90bce6643004/src/pyload/webui/app/blueprints/api_blueprint.py#L73","https://github.com/pyload/pyload/commit/461cd66f30fa9e96453fb4d8c5c47467e452363c","https://github.com/pyload/pyload/security/advisories/GHSA-vq8p-m3wm-gv5f","https://github.com/pyload/pyload/security/advisories/GHSA-vq8p-m3wm-gv5f"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-48484","score":0.00371,"percentile":0.30788,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-vq8p-m3wm-gv5f","url":"https://osv.dev/vulnerability/GHSA-vq8p-m3wm-gv5f","summary":"pyLoad: Lack of Input Size Validation Leads to Denial of Service (DoS) and Process Termination","modified":"2026-10-15T14:56:20.013961845Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev101"],"fixed":["0.5.0b3.dev101"]}]},{"id":"PYSEC-2026-4293","url":"https://osv.dev/vulnerability/PYSEC-2026-4293","summary":"pyLoad: Lack of Input Size Validation Leads to Denial of Service (DoS) and Process Termination","modified":"2026-10-15T14:45:14.923028514Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev101"],"fixed":["0.5.0b3.dev101"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
