Re: Wasm OCI Image Fetcher Bearer Realm SSRF Bypass

Hi,

This reply by "yan xu" convinced me that we're probably still talking to
AI running with little or no human supervision (maybe just copy-paste).
I think having these 4 sample reports in our list archives is enough for
a historical snapshot of AI slops that projects are getting at this
time, as well as for us to think of how to adapt to this sort of noise.

Indeed, there's a chance there's some substance to these vulnerability
claims.  Unfortunately, given all sorts of other inconsistencies in the
messages, I doubt anyone would want to spend time (and perhaps a more
capable AI's tokens) on reviewing them for real.

I never suggested you drop this header.

Thanks, but what you say above is inconsistent - if you "have already
patched the helper to omit X-Mailer", then even if we "block it anyway
as a hard filter" would make no difference.

Oh, but there were plenty of inconsistencies in them.  For example, two
of the reports claimed to have files attached, but none actually did, so
I assume those files never existed.

The 2026-06-25 date was also mentioned in your original posting, but
your tool actually sent it to oss-security on July 4.  It's weird that
you continue to insist on the older date.  This suggests that your
claims of prior communication with upstreams may also be hallucinations.

Hmm, this commit actually exists.  I'm surprised.

This is ridiculous.  oss-security is a public mailing list, so your
messages are already public and we're past any possible "coordinated
disclosure".  We also do not generally relay stuff, especially not
likely AI slops.

Please stop sending anything to this list at all, and don't bother
upstream projects with content that wasn't verified by a capable human.
