CVE-2026-4348: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in betterdocs BetterDocs Pro
BetterDocs Pro plugin for WordPress versions up to 3. 7. 0 contains an SQL Injection vulnerability in the AJAX actions `get_current_letter_docs` and `docs_sort_by_letter`. The issue arises because the `limit` POST parameter is directly interpolated into a SQL query string before being passed to the WordPress database prepare function, which does not parameterize this variable. Exploitation requires the Encyclopedia feature to be enabled. This vulnerability allows unauthenticated attackers to append additional SQL queries, potentially extracting sensitive database information. The CVSS score is 7. 5, indicating high severity. No official patch or remediation guidance is currently available from the vendor. No known exploits in the wild have been reported.
AI Analysis
Technical Summary
CVE-2026-4348 is an SQL Injection vulnerability in BetterDocs Pro for WordPress (up to version 3.7.0) affecting the AJAX actions `get_current_letter_docs` and `docs_sort_by_letter`. The vulnerability is due to improper handling of the `limit` POST parameter, which is directly interpolated into an SQL query string before being passed to `$wpdb->prepare()`. Since `$wpdb->prepare()` does not parameterize this interpolated value, it allows unauthenticated attackers to inject arbitrary SQL commands if the Encyclopedia feature is enabled. This can lead to unauthorized disclosure of sensitive database information. The vulnerability has a CVSS 3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high impact on confidentiality without affecting integrity or availability. No vendor patch or official remediation is currently documented.
Potential Impact
An unauthenticated attacker can exploit this vulnerability to perform SQL Injection attacks, potentially extracting sensitive information from the database. The vulnerability affects confidentiality but does not impact integrity or availability. Exploitation requires the Encyclopedia feature to be enabled in BetterDocs Pro settings. No known exploits in the wild have been reported to date.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, disabling the Encyclopedia feature in BetterDocs Pro settings will prevent exploitation of this vulnerability. Avoid exposing the affected AJAX actions to untrusted users.
