CVE-2025-15463: CWE-94 Improper Control of Generation of Code ('Code Injection') in hwk-fr Advanced Custom Fields: Extended
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.
AI Analysis
Technical Summary
CVE-2025-15463 is a code injection vulnerability in the Advanced Custom Fields: Extended WordPress plugin (versions up to 0.9.2.3). The flaw arises because the plugin executes user-supplied shortcodes without proper validation, allowing unauthenticated attackers to run arbitrary shortcodes via the do_shortcode function. This can result in partial confidentiality and integrity loss but does not affect availability. The vulnerability has a CVSS 3.1 score of 6.5 (medium severity). No patch or official remediation level has been published, and the plugin is not a cloud service.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to execute arbitrary shortcodes within the WordPress environment, potentially leading to limited confidentiality and integrity impacts. There is no indication of availability impact. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting access to vulnerable plugin functionality or disabling the plugin if feasible. Monitor vendor channels for updates and apply patches promptly once available.
