Advanced Custom Fields
Monthly
Authorization bypass in Advanced Custom Fields (ACF®) plugin for WordPress versions up to and including 6.8.1 allows unauthenticated remote attackers to overwrite the post_title and post_content of any post bound to a publicly accessible acf_form() instance. The attack requires no credentials, no user interaction, and low complexity - exploitable by anyone who can reach a page rendering a public-facing ACF front-end form. This vulnerability is not listed in the CISA KEV catalog and no public exploit code has been identified at time of analysis, but the zero-barrier attack path makes content integrity on exposed WordPress sites a real concern.
Unauthenticated privilege escalation in the Advanced Custom Fields: Extended (ACFE) WordPress plugin through version 0.9.2.5 allows remote attackers to create new administrator-level accounts on vulnerable sites. The flaw stems from the after_validate_save_post() function trusting an attacker-controlled POST parameter to bypass role allow-list and capability validation when a public ACFE frontend form with a Create User action is exposed. With a CVSS 9.8 and no public exploit identified at time of analysis, the vulnerability presents a direct site-takeover path on affected configurations.
Arbitrary file deletion in the Novarain/Tassos Framework system plugin (plg_system_nrframework) and the suite of Tassos.gr Joomla extensions that bundle it lets remote unauthenticated attackers delete arbitrary files on affected sites. The CVSS 4.0 vector (PR:N/UI:N) and the 'Authentication Bypass' tag indicate no credentials or interaction are needed, and the high integrity/availability impact reflects that deleting core files such as Joomla's configuration.php can lead to denial of service or site takeover. There is no public exploit identified at time of analysis, and EPSS is low (0.07%, 21st percentile) with no CISA KEV listing, indicating no observed exploitation despite the critical 9.3 base score.
Stored Cross-Site Scripting in Advanced Custom Fields: Font Awesome plugin for WordPress up to version 5.0.2 allows authenticated attackers with Subscriber-level access to inject arbitrary JavaScript via insufficiently validated JSON field values in the update_preview() function, resulting in script execution whenever any user visits an affected page. The vulnerability requires user interaction only in the sense that a victim must visit a page containing injected content; the attacker needs only Subscriber-level authentication to craft the malicious payload.
The The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 0.9.2.3. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
Unauthenticated attackers can bypass field-level authorization in Advanced Custom Fields (ACF) plugin versions up to 6.7.0 via AJAX endpoints that process user-supplied filter parameters without proper privilege checks, enabling disclosure of draft, private, and restricted post/page content that should be hidden by field configuration. The vulnerability affects any WordPress site with ACF installed and frontend forms exposed, requiring only network access and no user interaction. CVSS 5.3 reflects confidentiality impact with low attack complexity; no KEV status or public POC confirmed at analysis time.
The Advanced Custom Fields (ACF) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a custom text field in all versions up to, and including, 6.2.4 due to insufficient input. Rated medium severity (CVSS 6.4), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in WP Engine Advanced Custom Fields (ACF).1.1 through 6.0.2. Rated low severity (CVSS 3.7), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
Missing Authorization vulnerability in Anders Thorborg.4.12. Rated low severity (CVSS 3.1), this vulnerability is remotely exploitable. No vendor patch available.
The Advanced Custom Fields: Extended plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'acfe_form' shortcode in versions up to, and including, 0.8.9.3 due to insufficient. Rated medium severity (CVSS 6.4), this vulnerability is remotely exploitable, low attack complexity. This Cross-Site Scripting (XSS) vulnerability could allow attackers to inject malicious scripts into web pages viewed by other users.
