Wordfence just launched its bug bounty program. For the first 6 months, all awarded bounties receive a 10% bonus. View the announcement to learn more now!

Last week, there were 16 vulnerabilities disclosed in 16 WordPress Plugins and no WordPress themes that have been added to the Wordfence Intelligence Vulnerability Database, and there were 7 Vulnerability Researchers that contributed to WordPress Security last week. Review those vulnerabilities in this report now to ensure your site is not affected.

Our mission with Wordfence Intelligence is to make valuable vulnerability information easily accessible to everyone, like the WordPress community, so individuals and organizations alike can utilize that data to make the internet more secure. That is why the Wordfence Intelligence user interface, vulnerability API, webhook integration, and Wordfence CLI Vulnerability Scanner are all completely free to access and utilize both personally and commercially, and why we are running this weekly vulnerability report.

Enterprises, Hosting Providers, and even Individuals can use the Wordfence CLI Vulnerability Scanner to run regular vulnerability scans across the sites they protect. Or alternatively, utilize the vulnerability Database API to receive a complete dump of our database of over 12,000 vulnerabilities and then utilize the webhook integration to stay on top of the newest vulnerabilities added in real-time, as well as any updates made to the database, all for free.

New Firewall Rules Deployed Last Week

The Wordfence Threat Intelligence Team reviews each vulnerability to determine impact and severity, along with assessing the likelihood of exploitation, to verify that the Wordfence Firewall provides sufficient protection.

Smart Forms <= 2.6.84 – Missing Authorization to Authenticated (Subscriber+) Arbitrary Options Update
WAF-RULE-658 – Data redacted while we work with developer on a patch.
