 "notes": "Adnan Khan disclosed the issue-title prompt-injection and cache-poisoning chain on February 9. Cline initially reported no unauthorized release during the December 21–February 9 exposure window, but later confirmed that the wrong npm token had been revoked and the exposed token was used on February 17 to publish cline@2.3.0 with an OpenClaw postinstall script. impact_realized is tied to that confirmed unauthorized publish and installations during its eight-hour window, not to the hypothetical millions-user extension compromise.",
