CVE-2026-22470: 
WordPress vulnerability analysis and mitigation

CVE-2026-22470 is a Blind SQL Injection vulnerability in the FireStorm Professional Real Estate WordPress plugin (fs-real-estate-plugin) by FireStorm Plugins. It affects all versions up to and including 2.7.11, with no official patch available at the time of disclosure. The vulnerability was reported by researcher "Mrreee" on December 7, 2025, and published by Patchstack on January 6, 2026, with CVE assignment on January 22, 2026. It carries a CVSS v3.1 base score of 7.6 (High), assessed by CISA-ADP (Patchstack).

The vulnerability is classified as CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), enabling Blind SQL Injection attacks. Exploitation requires network access and high privileges (Administrator-level), with no user interaction needed and a changed scope, indicating the impact can extend beyond the vulnerable component. The attack vector is network-based with low complexity, meaning an authenticated administrator can craft malicious SQL payloads that are passed unsanitized to the database backend. No public proof-of-concept code has been identified at this time (Patchstack).

Successful exploitation allows an attacker with administrator-level access to interact directly with the underlying WordPress database through blind SQL injection techniques, primarily exposing sensitive data (high confidentiality impact). Integrity is not directly impacted, while availability suffers a low impact. The changed scope indicates that data from outside the plugin's direct context — such as WordPress user credentials, personal data, or other site content stored in the database — may be accessible to the attacker (Patchstack).

No evidence of active in-the-wild exploitation has been reported, and the EPSS score is very low at approximately 0.021%, reflecting a low probability of near-term exploitation. Patchstack classifies this as low priority with unlikely exploitation potential. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, and no exploit kits or weaponized code have been publicly identified. Exploitation requires high privileges (administrator access), which significantly limits the attacker pool (Patchstack).

1. Reconnaissance: Identify WordPress sites running the FireStorm Professional Real Estate plugin (fs-real-estate-plugin) version 2.7.11 or earlier using tools like WPScan or by inspecting plugin directories.
2. Obtain Administrator Credentials: Since exploitation requires high privileges, the attacker must first obtain valid WordPress administrator credentials through phishing, credential stuffing, or other means.
3. Identify Vulnerable Parameter: Log in as an administrator and navigate to plugin-specific admin pages or endpoints that accept user-supplied input passed to SQL queries.
4. Craft Blind SQL Injection Payload: Inject time-based or boolean-based blind SQL payloads (e.g., using SLEEP() or conditional expressions) into the vulnerable parameter to infer database contents character by character.
5. Extract Sensitive Data: Use automated tools such as sqlmap with session cookies to systematically extract WordPress database contents, including user credentials (hashed passwords), email addresses, and other sensitive site data (Patchstack).

• Logs: WordPress or web server access logs showing repeated requests to plugin-specific admin endpoints with unusual query parameters containing SQL syntax (e.g., SLEEP(), AND 1=1, OR 1=1, UNION SELECT).
• Database: Unexpected or anomalous database query patterns in MySQL slow query logs, particularly time-delayed queries indicative of time-based blind SQL injection.
• Network: Unusual high-frequency requests from a single authenticated session to the same plugin endpoint, potentially indicating automated blind SQL injection enumeration.
• Process: Elevated database CPU usage or query latency spikes consistent with SLEEP()-based injection attempts.

As of the disclosure date, no official patch has been released by FireStorm Plugins for the fs-real-estate-plugin. Site administrators are advised to deactivate and remove the plugin until a patched version becomes available. Patchstack users can leverage virtual patching to mitigate the vulnerability without removing the plugin. Additionally, restricting administrator account access, enforcing strong credentials, and enabling multi-factor authentication can reduce the risk of exploitation given the high privilege requirement (Patchstack).
