Okay 3rd (and last post) someone in the linked GitHub issue noticed that all of the tags in the project have been pointed to the malicious commit.

The malicious commit was made by a "renovate" bot - perhaps its creds were compromised?

The GitHub action ultimately outputs a double base64 encoded value that is the secrets it was able to extract.

See the second image for what this output looks like in Github action logs (I blacked out some of the output).
