The vulnerability description and associated CWEs indicate a race condition between post creation and deletion operations. However, without access to the specific code changes in the patched versions (8.1.9 and 9.4.2) or commit diffs, it's impossible to definitively identify the exact vulnerable functions. The vulnerability likely involves interaction between post creation and deletion logic, potentially in functions handling post persistence or permission checks, but insufficient information exists to pinpoint specific functions/paths with high confidence. The lack of GitHub patch/commit information significantly limits the ability to correlate the described race condition with concrete code implementations.
