{"cve":"CVE-2026-54254","nvd":{"published":"2026-09-15T15:17:18.170","modified":"2026-09-30T17:51:56.193","status":"Deferred","description":"Cyberdrop-DL is a bulk asynchronous downloader for multiple file hosts. From 8.5.0 until 9.14.0, the Pixeldrain crawler uses substring host matching instead of requiring the input host to be an exact member of SUPPORTED_DOMAINS, and then reuses that input host for API requests. When a Pixeldrain API key is configured, processing a crafted URL from an attacker-controlled lookalike host causes cyberdrop_dl/crawlers/pixeldrain.py to send the Authorization header to that host. The URL may be introduced through a third-party site that can cause downloads for other sites, and the attacker receives the user's Pixeldrain API key. This issue is fixed in version 9.14.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":5.9},"cvss_v3":null,"cwes":["CWE-20","CWE-200"],"references":["https://github.com/Cyberdrop-DL/cyberdrop-dl/commit/4479555ae3f9d56d7657d6179a5bac3123eb4e2b","https://github.com/Cyberdrop-DL/cyberdrop-dl/pull/1944","https://github.com/Cyberdrop-DL/cyberdrop-dl/releases/tag/9.14.0","https://github.com/Cyberdrop-DL/cyberdrop-dl/security/advisories/GHSA-f5pf-q7c7-m3vv"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-54254","score":0.00528,"percentile":0.44399,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f5pf-q7c7-m3vv","url":"https://osv.dev/vulnerability/GHSA-f5pf-q7c7-m3vv","summary":"Pixeldrain API key shared with unverified thirdparty sites","modified":"2026-07-23T15:11:45.835725135Z","packages":[{"ecosystem":"PyPI","name":"cyberdrop-dl-patched","purl":"pkg:pypi/cyberdrop-dl-patched","ranges":[">=8.5.0 <9.14.0"],"fixed":["9.14.0"]}]},{"id":"PYSEC-2026-3460","url":"https://osv.dev/vulnerability/PYSEC-2026-3460","summary":"Pixeldrain API key shared with unverified thirdparty sites","modified":"2026-07-23T15:00:10.910036474Z","packages":[{"ecosystem":"PyPI","name":"cyberdrop-dl-patched","purl":"pkg:pypi/cyberdrop-dl-patched","ranges":[">=8.5.0 <9.14.0"],"fixed":["9.14.0"]}]}],"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).
