Description

Kavita 0.5.2 before 0.5.4.1 contains a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files by supplying '../' sequences in the filename parameter. Attackers can send GET requests to /api/image/cover-upload with filename values like ../appsettings.json to retrieve configuration files outside the temp directory. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.

Detection & mitigation playbook

Vulnerability
  1. Detect

    Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`).

  2. Fix

    Upgrade the affected component to the fixed release for CVE-2022-51024, or apply your distribution's backported patch — distro builds are often patched at an older version number, so check your vendor's advisory rather than the upstream version alone.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
