Title
Stop Spammers Classic <= 2026.6 - Unauthenticated Stored Cross-Site Scripting via 'author' Parameter
Summary
The Stop Spammers Classic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'author' POST parameter in versions up to, and including, 2026.6. An unauthenticated POST handled on init stores the attacker-supplied author field (after sanitize_text_field, which does not escape single quotes) into the ss_stop_sp_reg_stats option history. The Log Report admin page then renders that stored value inside a single-quoted JavaScript string within a double-quoted onclick attribute using esc_js(); because esc_js() uses _wp_specialchars with ENT_COMPAT it does not escape single quotes, allowing the stored value to break out of the JS string literal and inject arbitrary JavaScript. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute whenever an administrator with manage_options access clicks the 'Report to SFS' link on an attacker-poisoned log row (the StopForumSpam API key must be configured for that link to be rendered — the field is empty by default). Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.

Title
Stop Spammers Classic <= 2026.1 - Cross-Site Request Forgery via Email Allowlist
Summary
The Stop Spammers Classic plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2026.1. This is due to missing nonce validation in the ss_addtoallowlist class. This makes it possible for unauthenticated attackers to add arbitrary email addresses to the spam allowlist via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. The vulnerability was partially patched in version 2026.1.

Title
Anti-Spam: Spam Protection | Block Spam Users, Comments, Forms <= 2024.7 - Cross-Site Request Forgery to Multiple Administrative Actions
Summary
The Anti-Spam: Spam Protection | Block Spam Users, Comments, Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2024.7. This is due to missing or incorrect nonce validation in the 'ss_option_maint.php' and 'ss_user_filter_list' files. This makes it possible for unauthenticated attackers to delete pending comments, and re-enable a previously blocked user via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
