CVE-2026-25418: 
WordPress vulnerability analysis and mitigation

CVE-2026-25418 is a SQL Injection vulnerability in the Bit Apps Bit Form WordPress plugin, classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). It affects all versions of the plugin up to and including 2.21.10. The vulnerability was published on February 19, 2026, and carries a CVSS v3.1 base score of 7.6 (High) (Feedly, Wordfence).

The vulnerability stems from insufficient sanitization of user-supplied input before it is incorporated into SQL queries within the Bit Form plugin (CWE-89). An authenticated attacker with high privileges (e.g., administrator-level access) can craft malicious SQL statements passed through plugin parameters, causing the database to execute unintended commands. The changed scope (S:C) in the CVSS vector indicates the impact can extend beyond the plugin itself to the underlying WordPress database. No public proof-of-concept code has been identified at this time (Feedly, Patchstack).

Successful exploitation primarily threatens confidentiality, allowing an attacker to extract sensitive data from the WordPress database — including user credentials, form submissions, and site configuration — with high confidentiality impact. Availability is marginally affected (low impact), while integrity is not directly impacted per the CVSS assessment. Because the scope is marked as changed, the attack can potentially reach data or resources beyond the plugin's own database tables, increasing the risk of broader site compromise (Feedly).

Exploitation requires network access and high-privilege authentication (e.g., WordPress administrator), which limits opportunistic exploitation but does not eliminate risk in environments with compromised admin accounts or insider threats. The EPSS score is approximately 0.021% (0.000210), indicating a currently low probability of widespread exploitation. No in-the-wild exploitation, threat actor attribution, or CISA KEV catalog listing has been reported as of the latest available data (Feedly).

1. Reconnaissance: Identify WordPress sites running the Bit Form plugin version ≤ 2.21.10 using tools like WPScan or Shodan with WordPress-specific fingerprinting.
2. Authentication: Obtain or compromise a high-privilege WordPress account (administrator role) through credential stuffing, phishing, or reuse of leaked credentials.
3. Locate vulnerable parameter: Navigate to the Bit Form plugin's administrative interface and identify input fields or API endpoints that interact with the database without proper sanitization.
4. Craft SQL payload: Inject a malicious SQL statement (e.g., ' UNION SELECT user_login, user_pass FROM wp_users-- -) into the vulnerable parameter to extract data from the WordPress database.
5. Exfiltrate data: Retrieve the query results from the HTTP response or use time-based/blind SQL injection techniques if output is not directly reflected, extracting credentials, form data, or other sensitive records (Feedly, Patchstack).

• Network: Unusual or malformed HTTP requests to Bit Form plugin endpoints containing SQL metacharacters (e.g., ', --, UNION, SELECT) in query parameters or POST body.
• Logs: WordPress or web server access logs showing repeated requests to Bit Form admin endpoints with anomalous parameter values; database error messages logged related to SQL syntax errors.
• Database: Unexpected queries in the MySQL general query log involving UNION SELECT, INFORMATION_SCHEMA, or wp_users table access originating from the WordPress application user.
• File System: Presence of unfamiliar files or web shells in the WordPress uploads or plugin directories following a suspected compromise.

Users should update the Bit Form plugin to a version beyond 2.21.10 as soon as a patched release is made available by Bit Apps. In the interim, administrators should restrict access to the WordPress admin panel using IP allowlisting or two-factor authentication to reduce the attack surface, given that exploitation requires high-privilege credentials. Monitoring database query logs for anomalous SQL patterns is also recommended as a detective control (Patchstack, Feedly).

Wordfence included this vulnerability in their weekly WordPress vulnerability report for the period of January 26 – February 1, 2026, highlighting it as part of broader plugin security tracking (Wordfence). The Hacker Wire also published a brief notice on the CVE, and it was catalogued by Patchstack and VulDB shortly after disclosure. No significant researcher commentary or broader media coverage has been identified beyond routine vulnerability aggregation.
