Plugin Security Certification (PSC) by CleanTalk

Favicon by RealFaviconGenerator (v1.3.45) is a WordPress plugin that automates the generation and deployment of platform-compatible favicons for desktop browsers, iOS devices, Android devices, Windows tablets, and more.

Modern favicon implementation requires multiple image sizes, platform-specific declarations, and compliance with different UI standards. This plugin simplifies the process by integrating WordPress with the RealFaviconGenerator service, generating all required assets in seconds.

Built for websites running on WordPress, the plugin eliminates manual favicon configuration while ensuring compatibility across browsers and operating systems.

Because the plugin interacts with an external generation service, performs file operations, and modifies theme headers, a structured security audit was conducted.

All 404 Redirect to Homepage (v5.5) is a WordPress plugin designed to automatically redirect 404 error pages to a specified destination using 301 SEO redirects. Instead of allowing visitors to encounter broken links, the plugin routes them to the homepage or a custom URL defined by the administrator.

Built for websites running on WordPress, the plugin focuses on improving SEO performance and user experience by minimizing exposure to 404 errors and preserving link equity.

However, because redirection logic directly affects HTTP responses and routing behavior, secure implementation is critical. Improper redirect handling can introduce open redirect vulnerabilities, redirect loops, or SEO manipulation vectors. Therefore, this plugin underwent a structured security audit.

Instant Indexing by Rank Math is a WordPress plugin that allows website owners to submit crawl requests to Google using the Google Indexing API immediately after publishing or updating content. Instead of waiting for standard search engine discovery cycles, the plugin automates indexing notifications directly from the WordPress dashboard.

Designed for websites running on WordPress, the plugin enables automated and manual submission of URLs to Google for faster crawling and indexing.

Google officially recommends the Indexing API primarily for Job Posting and Live Streaming websites. However, the plugin allows broader usage, and administrators should configure it responsibly.

Design libraries and site-building assistants accelerate WordPress creation, but they also expand the attack surface because they add editor-side UI, insert prebuilt content into posts/pages, and often rely on remote content delivery to fetch patterns and layouts. Weaknesses here can translate into stored XSS through unsafe pattern content insertion, authorization issues around who can import or modify design assets, CSRF-driven changes to editor behavior, or information disclosure through misconfigured endpoints and diagnostics. Extendify version 2.4.0 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64625, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for Gutenberg design libraries and editor augmentation tools.

Cookie notice plugins look “simple”, but they are security-relevant because they influence front-end script execution, store site-wide consent settings, and often expose customization fields that end up rendered for every visitor. If access control, request integrity, or output handling is weak, attackers can aim for stored/reflected XSS in banner content, CSRF-driven settings changes (silently altering consent behavior), or information exposure through misprotected endpoints and diagnostics. Cookie Notice & Compliance for GDPR / CCPA version 2.5.13 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64624, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for cookie notice and consent-management plugins.

Social feed plugins are valuable for keeping a website fresh, but they also expand the attack surface because they integrate with external platforms, render dynamic content on the front end, and store configuration that can include display templates, access tokens, and connection metadata. Weaknesses in access control, request integrity, or output handling can translate into stored XSS in rendered feed elements, CSRF-driven settings changes, data leakage through misprotected endpoints, or unsafe exposure of integration state. Smash Balloon Social Photo Feed – Easy Social Feeds Plugin version 6.10.0 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64623, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for social media embedding and feed-rendering plugins.

Media handling plugins may look “utility-only”, but they are security-relevant because they perform privileged operations on the filesystem, process large batches of content, and expose admin-side workflows that can be abused for resource exhaustion or unsafe file operations if protections are weak. Thumbnail regeneration, in particular, touches sensitive surfaces such as uploads directory write/delete, image metadata processing, and admin actions that can be triggered repeatedly. Regenerate Thumbnails version 3.1.6 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64622, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for media processing and batch maintenance tools.

Lead generation plugins are high-value targets because they sit at the intersection of front-end user interaction, dynamic content rendering, and conversion tracking. They commonly introduce new UI surfaces (popups, bars, inline optins), store campaign configuration, and integrate with external marketing services — which means weaknesses can translate into stored/reflected XSS in campaign output, CSRF-driven configuration changes, leakage of lead or account metadata, or abuse of endpoints used to render and manage campaigns. Popup Builder & Popup Maker for WordPress – OptinMonster Email Marketing and Lead Generation version 2.16.22 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64621, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for marketing, popup, and opt-in plugins.

Performance optimization plugins can be security-relevant even when they don’t “handle data,” because they influence front-end execution and can change how and when pages are loaded. Speculative loading, in particular, can trigger background navigations (prefetch/prerender) based on user interaction, which means weak defaults or poor exclusions could amplify server load (availability risk), accidentally pre-load state-changing URLs, or expose unsafe rendering surfaces if configuration is not handled defensively. Speculative Loading version 1.6.0 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64620, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for performance and browser preloading features.

Translation performance plugins are security-relevant because they operate on the boundary between localization runtime and filesystem-backed caches, generating and managing translation artifacts that affect how content is rendered across the entire site. If file handling, path validation, or access control is weak, attackers may try to influence which files are read or written, abuse conversion routines to cause resource exhaustion, or inject unsafe strings into admin-side status views. Performant Translations version 1.2.0 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64619, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for performance and localization tooling.
