CVE-2026-57739
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in AcyMailing Newsletter Team AcyMailing SMTP Newsletter acymailing allows Blind SQL Injection.This issue affects AcyMailing SMTP Newsletter: from n/a through <= 10.11.0.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAcyMailing SMTP Newsletter plugin for Joomla/WordPress versions up to 10.11.0 contains a blind SQL injection vulnerability due to improper neutralization of special elements in SQL commands. An unauthenticated attacker can exploit this to inject malicious SQL queries through vulnerable input parameters, potentially extracting sensitive data from the database or manipulating database contents.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AcyMailing component versionAccess Joomla administrator panel, navigate to Components > AcyMailing, or check the manifest XML file in /administrator/components/com_acymailing or the version file within the component directory. Run: grep -r 'version' /path/to/administrator/components/com_acymailing/ | head -20Affected if The displayed version number is 10.11.0 or lower (for example 10.10.0, 10.9.0, etc.)
-
Verify SMTP module is configuredIn Joomla admin, go to Components > AcyMailing > Configuration > SMTP tab. Check if SMTP server settings are saved and enabled. Alternatively, inspect the database table #__acymailing_config for smtp configuration records.Affected if SMTP configuration exists and the component is actively using SMTP for mail delivery (this indicates the vulnerable code path is reachable)
-
Locate the SQL injection entry pointReview HTTP requests to AcyMailing front-end or back-end endpoints, specifically those handling SMTP configuration parameters. Common endpoints include: /index.php?option=com_acymailing&ctrl=config&task=smtp or similar routes. Inspect the request parameters for unsanitized input being passed to database queries.Affected if Parameters related to SMTP configuration (such as smtp_host, smtp_username, smtp_password, or similar fields) are processed without parameterized queries or input validation
If the AcyMailing version is 10.11.0 or lower and the SMTP feature is actively configured, the environment is likely affected by this blind SQL injection vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade AcyMailing SMTP Newsletter to the latest version beyond 10.11.0 where the vulnerability has been patched. If immediate upgrade is not possible, restrict access to the affected component and implement web application firewall rules to detect and block SQL injection attempts.
