Security readout for executives and security teams
Plain-English summary
CVE-2026-25413 is a critical arbitrary file upload issue in the WordPress WPBookit Pro plugin through version 1.6.18. A low-privileged authenticated user may be able to upload dangerous files, potentially compromising the website. Prioritize sites using this plugin, especially public WordPress sites with user accounts.
Executive priority
Treat as urgent for any public WordPress site using WPBookit Pro. The score is critical and the issue can affect site confidentiality, integrity, and availability. If the plugin is not present, priority drops to routine documentation.
Technical view
The CVE describes CWE-434: unrestricted upload of files with dangerous type in iqonicdesign WPBookit Pro wpbookit-pro through <= 1.6.18. CVSS 3.1 is 9.9: network exploitable, low complexity, low privileges required, no user interaction, scope changed, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is likely limited to WordPress installations running WPBookit Pro through version 1.6.18. Risk increases where untrusted or lightly trusted users can authenticate. The provided sources do not identify affected free editions, other iqonicdesign plugins, or hosting platforms.
Exploitation context
The CVE is not listed as KEV in the provided bundle, and no cited source states active exploitation. The vulnerability class can be severe because uploaded dangerous files may lead to site takeover, but the sources do not provide exploit details or confirmed exploitation.
Researcher notes
Evidence is sparse beyond the CVE metadata and Patchstack entry. The affected range is stated as through 1.6.18, but the provided bundle does not name a fixed version, workaround, exploit availability, or authentication role requirements beyond CVSS PR:L.
Mitigation direction
- Identify WordPress sites running WPBookit Pro.
- Check whether installed WPBookit Pro version is <= 1.6.18.
- Review vendor and Patchstack guidance for a fixed version or workaround.
- Restrict plugin access to trusted users until remediated.
- Remove or disable the plugin if business impact allows.
Validation and detection
- Inventory WordPress plugins across production and staging sites.
- Confirm WPBookit Pro version from WordPress admin or asset records.
- Review web server and WordPress logs for suspicious uploads.
- Check uploads and plugin directories for unexpected executable files.
- Verify remediation against vendor or Patchstack advisory guidance.
