{"cve":"CVE-2025-64184","nvd":{"published":"2025-11-07T04:15:46.947","modified":"2026-06-17T09:53:58.517","status":"Deferred","description":"Dosage is a comic strip downloader and archiver. When downloading comic images in versions 3.1 and below, Dosage constructs target file names from different aspects of the remote comic (page URL, image URL, page content, etc.). While the basename is properly stripped of directory-traversing characters, the file extension is taken from the HTTP Content-Type header. This allows a remote attacker (or a Man-in-the-Middle, if the comic is served over HTTP) to write arbitrary files outside the target directory (if additional conditions are met). This issue is fixed in version 3.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22"],"references":["https://github.com/webcomics/dosage/commit/336a9684191604bc49eed7296b74bd582151181e","https://github.com/webcomics/dosage/security/advisories/GHSA-4vcx-3pj3-44m7"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:14:53.307938015+00:00"},"epss":{"cve":"CVE-2025-64184","score":0.00486,"percentile":0.4186,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-4vcx-3pj3-44m7","url":"https://osv.dev/vulnerability/GHSA-4vcx-3pj3-44m7","summary":"Dosage vulnerable to a Directory Traversal through crafted HTTP responses","modified":"2026-07-07T17:57:22.746862685Z","packages":[{"ecosystem":"PyPI","name":"dosage","purl":"pkg:pypi/dosage","ranges":["<3.2"],"fixed":["3.2"]}]},{"id":"PYSEC-2026-1316","url":"https://osv.dev/vulnerability/PYSEC-2026-1316","summary":"Dosage vulnerable to a Directory Traversal through crafted HTTP responses","modified":"2026-07-07T17:46:39.481876030Z","packages":[{"ecosystem":"PyPI","name":"dosage","purl":"pkg:pypi/dosage","ranges":["<3.2"],"fixed":["3.2"]}]}],"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).
