AI-suggested
A fix is available in version 5.2.4 of the Quick Page/Post Redirect Plugin, which restores the official update channel and removes the backdoor. Site operators should remove any versions before 5.2.4, reinstall the clean 5.2.4 version from WordPress.org, delete any leftover updater/ directory, verify plugin files using the WordPress CLI checksum verification command, clear opcode caches, and treat any site that ran the tampered build as potentially compromised.
Description
The Quick Page/Post Redirect Plugin for WordPress versions 5.2.1 through before 5.2.4 contained a hidden update mechanism that fetched updates from a malicious server controlled by the plugin author instead of the official WordPress.org repository. This mechanism was exploited in March 2021 to deliver a backdoored plugin build (version 5.2.3) that injected arbitrary content into pages and delivered arbitrary code, primarily serving SEO spam links to visitors and search engine crawlers. The plugin was fixed in version 5.2.4, which restored the official update channel and removed the backdoor.
