CVE-2026-2941: CWE-862 Missing Authorization in plugli Linksy Search and Replace
The Linksy Search and Replace plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'linksy_search_and_replace_item_details' function in all versions up to, and including, 1.0.4.

AI Analysis
Technical Summary
CVE-2026-2941 describes a missing authorization (CWE-862) vulnerability in the Linksy Search and Replace plugin for WordPress. The vulnerability arises because the function 'linksy_search_and_replace_item_details' does not properly verify user capabilities before allowing database modifications. As a result, any authenticated user with subscriber or higher privileges can update arbitrary database entries, including their own user role, enabling privilege escalation to administrator. This vulnerability affects all versions up to and including 1.0.4.
Potential Impact
Successful exploitation allows an authenticated attacker with minimal privileges to escalate to administrator by modifying the wp_capabilities database field. This results in full control over the WordPress site, including the ability to modify content, install plugins, and change site settings. The vulnerability has a CVSS score of 8.8 (high severity), indicating a significant risk to confidentiality, integrity, and availability.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict plugin usage to trusted users only and consider disabling or removing the plugin to prevent exploitation.
