Overview

CVE-2026-32482 describes an unrestricted upload of a file with a dangerous type (CWE-434) in the deothemes Ona product. According to the record, the flaw allows a web shell to be uploaded to a web server. The record was published on 2026-03-25 with Patchstack's audit address as the CNA.

Impact

  • The CNA reports a CVSS 3.1 base score of 9.9 (Critical) with vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H.
  • The vector indicates a network attack vector, low attack complexity, low privileges required, no user interaction, a changed scope, and high impact on confidentiality, integrity and availability.
  • A web shell on a server would give an attacker a persistent remote foothold. This is an inference from the description rather than a statement in the sources.

Affected products and versions

  • Product: deothemes Ona, as named in the record.
  • The description states the affected range as from n/a through less than 1.24.
  • The structured affected list in the record is empty, so exact boundaries should be confirmed against the vendor and the Patchstack entry.
  • The reference path refers to a WordPress theme. This is an inference from the URL only.

Exploitation status

  • The record shows the CVE is not listed in the CISA KEV catalog, so active exploitation is not confirmed by that source.
  • No confirmed exploitation appears in the sources consulted.
  • The record gives an EPSS probability of 0.00479 with a percentile of 0.39633.

Remediation and mitigation

  • Identify whether the Ona theme is installed and which version is in use.
  • Plan an update to version 1.24 or later, since the description places affected versions below 1.24. Confirm this with the vendor.
  • If an update cannot be applied immediately, restrict upload functionality to trusted roles, enforce server-side file type validation, and store uploads outside executable paths.
  • Consult the Patchstack entry and the NVD record for guidance.

Detection guidance

  • Review upload and theme directories for unexpected script or executable files, especially recently modified ones.
  • Monitor web server logs for unusual requests to upload handlers and for newly created files in web-accessible paths.
  • Apply file integrity monitoring to theme directories and web roots.

Limitations of the available information

  • The title field was empty in the record, so the titles here are derived from the description.
  • The NVD status is recorded as Deferred.
  • The structured data lists no fixed version; the 1.24 boundary is inferred from the description.
  • The record does not include the vendor's own advisory text.
