Security readout for executives and security teams
Plain-English summary
CVE-2026-1674 affects the Gutena Forms WordPress plugin through version 1.6.0. A logged-in user with Contributor-level access or higher can change certain WordPress option values without proper authorization. This could disrupt site availability or alter settings such as user registration.
Executive priority
Treat as a near-term WordPress maintenance item, not an emergency unless the site allows many Contributor-level users or has signs of account compromise. Prioritize public-facing, business-critical WordPress sites first.
Technical view
The flaw is missing authorization, CWE-862, in save_gutena_forms_schema(). Authenticated low-privilege users can update option values to structured array values. The CVSS 3.1 score is 6.5, with network access, low complexity, low privileges, no user interaction, and high integrity impact.
Likely exposure
Exposure is limited to WordPress sites running Gutena Forms up to and including 1.6.0, especially where Contributor or higher accounts are assigned to untrusted users, contractors, or compromised accounts.
Exploitation context
The sources do not report active exploitation, and this CVE is not listed as KEV. Exploitation requires valid WordPress authentication with Contributor-level access or above, reducing broad internet-scale risk but increasing insider and account-takeover concern.
Researcher notes
Evidence supports an authenticated authorization bypass in save_gutena_forms_schema(). Public sources identify affected versions through 1.6.0 and a WordPress Trac changeset, but the bundle does not clearly name a fixed version. Avoid assuming broader unauthenticated impact.
Mitigation direction
- Identify WordPress sites using Gutena Forms version 1.6.0 or earlier.
- Check the WordPress plugin repository or vendor guidance for the patched release.
- Update Gutena Forms when a vendor-supported fix is available.
- Restrict Contributor and higher roles to trusted users only.
- Review and remove unnecessary WordPress accounts with publishing-related roles.
Validation and detection
- Confirm installed Gutena Forms versions across WordPress assets.
- Verify whether the referenced Trac changeset is included in your installed plugin version.
- Review Contributor, Author, Editor, Administrator, and custom-role account assignments.
- Inspect recent option-setting changes for unexpected structured array values.
- Monitor for unexplained site errors or unexpected registration setting changes.

Missing Authorization
Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
