{"cve":"CVE-2026-75597","nvd":{"published":"2026-10-09T17:16:48.550","modified":"2026-10-09T18:17:14.173","status":"Deferred","description":"pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev101, the `/web/<path:filename>` route in `src/pyload/webui/app/blueprints/app_blueprint.py` renders Jinja2 templates without any authentication requirement. Every equivalent direct route (`/logs`, `/settings`, `/queue`, `/dashboard`, etc.) is protected by `@login_required`, but the underlying templates for all of these pages are accessible unauthenticated via this endpoint. Combined with an exception attribute typo in `src/pyload/webui/app/handlers.py` (`exc.desc` instead of `exc.description`), internal Jinja2 variable names are leaked in HTTP 500 response bodies to unauthenticated callers. An attacker can also enumerate all valid template names by observing 200 vs 500 response differentiation. 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:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-209","CWE-306"],"references":["https://github.com/pyload/pyload/commit/e80c940cd604e60d93e3164429d4fc4aac54468d","https://github.com/pyload/pyload/security/advisories/GHSA-j92p-c242-7hfx","https://github.com/pyload/pyload/security/advisories/GHSA-j92p-c242-7hfx"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-75597","score":0.00296,"percentile":0.22049,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j92p-c242-7hfx","url":"https://osv.dev/vulnerability/GHSA-j92p-c242-7hfx","summary":"pyLoad: Unauthenticated access to /web/<path:filename> bypasses authentication on sensitive templates and leaks internal error details via exception attribute typo","modified":"2026-10-15T14:55:39.919409496Z","packages":[{"ecosystem":"PyPI","name":"pyload-ng","purl":"pkg:pypi/pyload-ng","ranges":["<0.5.0b3.dev101"],"fixed":["0.5.0b3.dev101"]}]},{"id":"PYSEC-2026-4292","url":"https://osv.dev/vulnerability/PYSEC-2026-4292","summary":"pyLoad: Unauthenticated access to /web/<path:filename> bypasses authentication on sensitive templates and leaks internal error details via exception attribute typo","modified":"2026-10-15T14:45:14.127210245Z","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).
