Quick quotes WordPress plugin: Missing authorization in AJAX action allows option changes
Summary
The Quick quotes WordPress plugin up to and including version 1.0.0 does not check capabilities or nonces on one of its AJAX actions. An unauthenticated attacker can choose which option is written, which allows changes to arbitrary site settings and can make the website unavailable. No fixed version is known and no vendor advisory was found.
Affected
- Quick quotes WordPress plugin (slug quick-quotes-wpshare247), versions 0 to 1.0.0 inclusive
- Vendor and developer are unknown.
Fixed in
- Unknown. WPScan lists no known fix.
Workaround
- Deactivate and delete the plugin if it is not essential; this is the only complete fix available.
- If the plugin must stay, restrict access to the affected AJAX endpoint with a web application firewall or reverse-proxy rule and test the rule carefully.
- Check the WordPress options table for unexpected changes, especially site URL, admin email and membership or registration settings.
Exploitation
- CISA SSVC: exploitation none, automatable yes, technical impact partial.
- Not listed in the CISA KEV catalogue.
- No reports of in-the-wild exploitation found.
- Public proof-of-concept status is unconfirmed.
- EPSS is very low (about 0.15%).
Our recommendation
- Check whether the Quick quotes plugin is installed on any WordPress site, including inactive installations.
- Remove the plugin if it is not required; if it is required, apply the restriction described under workaround.
- Review WordPress options for unexpected changes and keep recent backups available for restore.
- Monitor the sites for unexplained downtime or configuration changes.
