CVE-2025-2809
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 · uneditedThe azurecurve Shortcodes in Comments plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.0.2. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.
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 confidenceThe azurecurve Shortcodes in Comments WordPress plugin fails to validate user input before passing it to do_shortcode(), allowing unauthenticated attackers to execute arbitrary WordPress shortcodes. This enables potential injection of malicious shortcode content that could lead to data exposure or further compromise.
