Several WordPress.org Plugins <= Various Versions - Injected Backdoor

Several plugins for WordPress hosted on WordPress.org have been compromised and injected with malicious PHP scripts. A malicious threat actor compromised the source code of various plugins and injected code that exfiltrates database credentials and is used to create new, malicious, administrator users and send that data back to a server. All plugins have received updates reverting any added malicious code. Simply Show Hooks affected version (1.2.1) is the same as the patched version (1.2.1) - it does not appear that the malicious copy was ever officially released, so sites running 1.2.1 should be unaffected, though it is a good idea to run a complete Wordfence scan and verify that there are no rogue administrator accounts present.

Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: PowerPress Podcasting plugin by Blubrry 11.9.6 closes this, and updating the plugin is the step that ends it.
