| Explanation | plugin calls `::buildUpdateChecker()` — the factory entry point of the Yahnis Elsts Plugin Update Checker library. A plugin distributed through wordpress.org that registers its own update source is bypassing the Plugin Review Team: every install polls the non-wp.org URL on cron and installs whatever JSON + zip it returns, with full plugin-author permissions. This is the mechanism behind the `anadnet`/quick-pagepost-redirect-plugin compromise (2021) where the author seeded 70,000+ installs through tagged releases and then removed the library from trunk to hide the persistence. Any URL argument pointing away from `downloads.wordpress.org`/`api.wordpress.org` is the hijack signal. |
