Security readout for executives and security teams
Plain-English summary
A logged-in WordPress user with Contributor-level access or higher could reset settings for the Dealia – Request a quote plugin. This is not a site takeover issue based on the provided data, but it can disrupt quote-request functionality or business workflows that depend on the plugin.
Executive priority
Treat as a medium-priority WordPress plugin issue. Prioritize sites where quote requests drive revenue or where many lower-privileged users have accounts. Remediate through vendor guidance, access control review, or temporary disablement if business impact is high.
Technical view
CVE-2026-2504 is a missing authorization issue in Dealia – Request a quote up to and including 1.0.7. Multiple admin AJAX handlers verify DEALIA_ADMIN_NONCE but lack a manage_options capability check. The nonce is exposed to users with edit_posts capability, allowing Contributor+ users to reset plugin configuration.
Likely exposure
Exposure is limited to WordPress sites running Dealia – Request a quote versions up to 1.0.7 and allowing Contributor-level or higher untrusted accounts. Sites without the plugin, without such accounts, or with stronger role controls are less exposed.
Exploitation context
The vulnerability requires authenticated WordPress access with Contributor privileges or above. The CVSS score is 4.3, reflecting low attack complexity but limited integrity impact. The source bundle does not show CISA KEV listing or public evidence of active exploitation.
Researcher notes
The key issue is authorization, not nonce absence. Sources identify AJAX handlers in AdminSettingsController.php that verify nonce without manage_options checks, while PostsController.php exposes the admin nonce to edit_posts users. Evidence is sufficient for affected behavior, but the bundle does not identify a fixed version.
Mitigation direction
- Identify whether Dealia – Request a quote is installed and its version.
- Review vendor or WordPress plugin guidance for releases newer than 1.0.7.
- Limit Contributor-level access to trusted users only.
- Temporarily disable the plugin if configuration resets would cause unacceptable business impact.
- Monitor plugin settings for unexpected resets or changes.
Validation and detection
- Check WordPress plugin inventory for dealia-request-a-quote.
- Confirm installed version is not within the affected range.
- Review user accounts with Contributor, Author, Editor, or Administrator roles.
- Inspect plugin configuration history for unexpected resets.
- Track vendor advisory pages for patch or mitigation updates.
