With a CVSS v3.1 base score of 9.3, the flaw can be triggered remotely by an unauthenticated attacker over the network with no user interaction required, enabling exfiltration of sensitive data from the underlying WordPress database.

Technical details

  • Root cause: Improper neutralization of special elements in SQL commands — user-supplied input is not sufficiently sanitized or escaped before being incorporated into database queries, enabling blind (inferential) SQL injection.
  • Trigger conditions: No authentication, no elevated privileges, and no user interaction are required. The attack can be executed directly over HTTP/HTTPS by any internet-accessible attacker.
  • Attack vector: Remote, unauthenticated, network-based (AV:N/AC:L/PR:N/UI:N). Low attack complexity means no special conditions or race conditions must be met.
  • Impact: Scope is changed (S:C), meaning the vulnerability’s effects extend beyond the plugin’s own component to the broader WordPress database. Confidentiality impact is rated High (C:H), allowing an attacker to extract sensitive database contents such as user credentials, email subscriber lists, and site configuration data. Availability impact is rated Low (A:L). Integrity is not directly affected (I:N).

Affected software

  • AcyMailing SMTP Newsletter (WordPress plugin) — all versions from inception through 10.11.0 (inclusive)

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
