CVE-2025-49452: PostaPanduri SQL Injection Vulnerability

CVE-2025-49452 Overview

CVE-2025-49452 is a SQL Injection vulnerability affecting the Adrian Ladó PostaPanduri WordPress plugin. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. Attackers can exploit this issue remotely without authentication or user interaction. All versions of PostaPanduri up to and including 2.1.3 are affected. The vulnerability has a CVSS 3.1 score of 9.3, reflecting network-based exploitation, low attack complexity, and a scope change that can impact backend database resources beyond the vulnerable component.

Critical Impact
Unauthenticated remote attackers can inject arbitrary SQL into the plugin's database queries, exposing sensitive WordPress data and degrading database availability.

Affected Products

Adrian Ladó PostaPanduri WordPress plugin versions through 2.1.3
WordPress sites running PostaPanduri as an active plugin
Database backends serving the affected WordPress installation

Technical Details for CVE-2025-49452

Vulnerability Analysis

The vulnerability resides in the PostaPanduri plugin's query handling logic. User-supplied input reaches SQL statements without sufficient sanitization or parameterization. The plugin concatenates request parameters directly into queries that interact with the WordPress database. This pattern enables attackers to break out of the intended query context and append malicious SQL clauses. Because the issue is reachable over the network and requires no privileges, mass exploitation against exposed WordPress instances is feasible. Successful injection can disclose stored data such as user records, session metadata, and other plugin tables. The scope change indicated by the CVSS vector reflects impact extending beyond the plugin into the shared database engine that serves the entire WordPress site.

Root Cause

The root cause is improper neutralization of special characters [CWE-89] in SQL command construction. The plugin fails to use prepared statements or the WordPress $wpdb->prepare() API consistently. Input intended as data is interpreted as SQL syntax, allowing attackers to inject query fragments, UNION clauses, and conditional payloads.

Attack Vector

The attack vector is network-based. An unauthenticated remote attacker sends crafted HTTP requests to a vulnerable PostaPanduri endpoint. The injected payload alters the executing SQL statement. No user interaction or prior authentication is required. Refer to the Patchstack SQL Injection Vulnerability advisory for technical details on the affected parameter and endpoint.

No verified public exploit code is available at this time. The vulnerability manifests when crafted query string or POST parameters reach unparameterized SQL execution paths inside the plugin.

Detection Methods for CVE-2025-49452

Indicators of Compromise

HTTP requests targeting PostaPanduri plugin endpoints containing SQL metacharacters such as ', --, UNION SELECT, or SLEEP(
Unexpected database errors logged by WordPress or MySQL referencing PostaPanduri tables
New or modified WordPress administrator accounts with no corresponding audit trail
Outbound connections from the web server immediately following suspicious requests to the plugin

Detection Strategies

Inspect web server access logs for anomalous query strings hitting PostaPanduri plugin paths under /wp-content/plugins/postapanduri/
Enable WordPress debug logging and review wp-content/debug.log for wpdb errors
Deploy a web application firewall ruleset that flags SQL injection patterns against WordPress plugin endpoints

Monitoring Recommendations

Monitor MySQL slow query and error logs for malformed or unusually long queries originating from PostaPanduri code paths
Alert on spikes of 4xx or 5xx responses from plugin URLs that may indicate injection probing
Correlate authentication anomalies and privilege changes with recent traffic to the vulnerable plugin

How to Mitigate CVE-2025-49452

Immediate Actions Required

Deactivate the PostaPanduri plugin on all WordPress instances until a patched release is available
Restrict access to WordPress administrative and plugin endpoints using IP allowlists where feasible
Audit the WordPress database for unauthorized users, modified options, and unexpected table contents
Rotate WordPress secret keys, administrator passwords, and any API tokens stored in the database

Patch Information

No fixed version is listed in the available advisory data. All versions through 2.1.3 remain affected. Consult the Patchstack advisory for the latest vendor remediation status before reactivating the plugin.

Workarounds

Remove the PostaPanduri plugin directory from wp-content/plugins/ until a verified fix is released
Deploy WAF rules that block SQL injection signatures targeting requests to PostaPanduri endpoints
Apply the principle of least privilege to the WordPress database user to limit damage from successful injection

bash

# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate postapanduri
wp plugin delete postapanduri

# Example ModSecurity rule to block obvious SQLi against the plugin path
SecRule REQUEST_URI "@contains /wp-content/plugins/postapanduri/" \
  "chain,phase:2,deny,status:403,id:1004952,msg:'Block SQLi attempt against PostaPanduri'"
  SecRule ARGS "@rx (?i)(union(\s|/\*.*\*/)+select|sleep\s*\(|--\s|;\s*drop\s+table)"
