Source: Redux.io.\nThe first bug (CVE-2021-38312) rates 7.1 out of 10 on the CVSS scale, making it high-severity. It arises from the plugin\u2019s use of the WordPress REST API, which processes requests to install and manage the blocks. It fails to authorize user permissions correctly, according to Wordfence.\n\n\u201cWhile the REST API Endpoints registered under the redux/v1/templates/ REST Route used a permission_callback to verify a user\u2019s permissions, this callback only checked whether or not the user sending the request had the edit_posts capability,\u201d Wordfence researchers noted in a Wednesday posting.\n\nThat means that users with lower permissions, such as contributors and authors, could install any plugin in the WordPress repository via the redux/v1/templates/plugin-install endpoint, researchers said, or they could use the redux/v1/templates/delete_saved_block endpoint to erase posts.\n\nThe second, medium-severity vulnerability (CVE-2021-38314) rates 5.3 on the CVSS scale. It exists because the Gutenberg Template Library &amp; Redux Framework plugin registers several AJAX actions available to unauthenticated users, one of which is deterministic and predictable, making it possible to uncover what the $support_hash for a site would be.\nSee Also: Complete Offensive Security and Ethical Hacking Course \u201cThis $support_hash AJAX action, which was also available to unauthenticated users, called the support_args function in redux-core/inc/classes/class-redux-helpers.php, which returned potentially sensitive information such as the PHP version, active plugins on the site and their versions, and an unsalted md5 hash of the site\u2019s AUTH_KEY and SECURE_AUTH_KEY,\u201d according to Wordfence.\n\nResearchers added that an attacker could use the information to plan a website takeover using other vulnerable plugins.\n\nRedux.io has issued a patch, in version 4.2.13.\n\nWordfence researchers said users should update their plugins as soon as possible: \u201cWhile neither of these could be used directly to take over a site, both vulnerabilities could be useful tools in the hands of a skilled attacker,\u201d they said.\nSee Also: Critical Valve Bug Lets Gamers Add Unlimited Funds to Steam Wallets WordPress Plugin Problems PersistThese are only the latest WordPress plugin vulnerabilities to come to light. Other notable vulnerabilities this year include:\n\n* January: Researchers warned of two vulnerabilities\u00a0(one critical) in a WordPress plugin called Orbit Fox that could allow attackers to inject malicious code into vulnerable websites and/or take control of a website.\n* January:\u00a0A plugin called PopUp Builder, used by WordPress websites for building pop-up ads for newsletter subscriptions, was found to have a vulnerability\u00a0that could be exploited by attackers to send out newslet[...]", "creation_timestamp": "2026-09-01T20:02:25.825833Z"}
