Attack Vectors

CVE-2026-2025 is a Medium-severity vulnerability (CVSS 5.3) affecting the WordPress plugin Mail Mint – Newsletters, Email Marketing, Automation, WooCommerce Emails, Post Notification, and more (slug: mail-mint) in versions below 1.19.5.

The issue is categorized as an Unauthenticated Information Exposure risk. In practical terms, this means an attacker may be able to access sensitive information without needing a login. Because it is reachable over the network and requires no user interaction, it can be probed at scale by opportunistic attackers and automated scanners.

Security Weakness

The core weakness is sensitive information exposure: the plugin can unintentionally reveal sensitive user or configuration data to unauthenticated visitors in affected versions. While this does not indicate the attacker can change content or take over the site directly, it can still leak information that should remain private.

Per the published advisory, the impacted versions are all versions up to (but not including) 1.19.5. The recommended remediation is to update to 1.19.5 or a newer patched version.

Technical or Business Impacts

For marketing, ecommerce, and leadership teams, the business risk is primarily about data exposure and downstream consequences. If sensitive user or configuration details are extracted, this can increase the likelihood of:

Privacy and compliance exposure: Leaked user-related data can create regulatory and contractual risk (depending on what data is exposed), including incident response obligations, customer notifications, and reputational damage.

Increased fraud and phishing risk: Configuration details or user information can be used to craft more convincing phishing messages or social engineering attempts against staff, customers, or subscribers—especially damaging for brands that rely heavily on email marketing and deliverability trust.

Operational disruption: Even without direct site takeover, investigations, emergency patching, and stakeholder communications can consume time and budget, and can interrupt campaign timelines.

Recommended action: confirm whether Mail Mint is installed and identify the running version; if it is < 1.19.5, prioritize an update to 1.19.5+ promptly and review access logs for unusual unauthenticated requests around plugin-related endpoints.
