Description

Impact

When using file:<location> command and <location> is web URL location (http, https). mangadex-downloader will try to open and read a file in local disk if the content from online file is exist-as-a-file in victim computer

So far, the app only read the files and not execute it. But still, when someone reading your files without you knowing, it's very scary.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for mangadex-downloader, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update mangadex-downloader to 1.7.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r9x7-2xmr-v8fw is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
