Technical Analysis
CVE-2026-80439 is a vulnerability in the Redirection for Contact Form 7 WordPress plugin affecting versions from 2.2.7 before 3.2.11. The plugin fails to properly neutralize special elements in output used by a downstream component, specifically allowing shortcodes submitted via form values to be executed when substituted into action settings. This improper neutralization (CWE-74) enables unauthenticated attackers to run any shortcode registered on the site and access its output, potentially exposing sensitive information or functionality.
Potential Impact
An unauthenticated attacker can execute arbitrary shortcodes registered on the WordPress site by submitting specially crafted form values. This can lead to unauthorized disclosure of information accessible via those shortcodes. The vulnerability does not allow privilege escalation or denial of service but can leak data through shortcode outputs.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider disabling the vulnerable plugin or restricting access to the affected functionality. Monitor vendor channels for updates and apply patches promptly once released.
