Other vulnerabilities in Custom Field Template
See all- CVE-2026-12995Medium
The Custom Field Template plugin for WordPress in versions up to and including 2.7.8 is vulnerable to Insecure Direct Object Reference via edit_meta_value due to missing validation on a user-controlled key. An authenticated attacker with contributor-level access or higher can delete arbitrary media attachments site-wide by supplying any numeric attachment ID in the file-field parameter alongside the corresponding delete flag, causing content loss and broken pages.
- CVE-2026-9855Medium
The Custom Field Template plugin for WordPress is vulnerable to generic SQL Injection via the 'post_ID' parameter in all versions up to and including 2.7.8 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This allows authenticated attackers with contributor-level access and above to append additional SQL queries into existing ones, potentially extracting sensitive information from the database. The capability check is bypassable because WordPress internally casts $id to an integer for permission evaluation while the full unsanitized string is passed to the SQL sink.
- CVE-2026-57687High
The Custom Field Template plugin for WordPress versions 2.7.8 and earlier contains a Contributor SQL Injection vulnerability. An attacker with contributor privileges can inject malicious SQL queries into the database.
- CVE-2025-68607Medium
Custom Field Template up to version 2.7.7 contains a Stored XSS vulnerability due to improper input neutralization during web page generation. This allows an attacker to permanently inject a malicious script that will execute in other users' browsers.
