CVE-2026-101325

Read full description

The Newsletters plugin for WordPress is vulnerable to time-based SQL Injection via the 'id' parameter in all versions up to, and including, 4.18.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. An attacker can obtain the required nonce and subscriberauth cookie without a WordPress account by simply subscribing through the public newsletter form and opening the management link sent via email; the ownership check verifies only the subscriber_id field and does not validate that the injected id parameter belongs to the authenticated subscriber.

Evidence context and dated references

Reality is general threat/review priority, combining observed exploitation, CVSS severity and fresh EPSS. Evidence confidence is separate. This is not calibrated risk, a victim count or an asset-specific assessment. A range reflects missing numeric inputs. Published 10 days ago. Exploitation evidence usually takes weeks to show up: a low reality score can mean there is no data yet, not that the flaw is mild.
