There was a problem hiding this comment.
Clarification on this line.
The original vector string could not be parsed by the advisory edit form,
which blocked submission. It was normalized by removing the trailing
"Not Defined" (:X) threat, environmental, and supplemental placeholders.
All eleven base metrics are unchanged
(AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N) and the score
remains 8.7 / High, matching the published CNA assessment.
My PR description note about "no changes to severity" referred to the score
and qualitative rating — it was imprecise regarding the vector formatting.
Happy to revert this line if you would prefer the original string retained.

Adds the missing ecosystem and package mapping for this unreviewed advisory.
The affected package is published on Hex, but no ecosystem or package name
was assigned. As a result, Erlang/Elixir projects depending on cowlib do not
receive Dependabot alerts for this vulnerability.
The Erlang Ecosystem Foundation CNA record (already listed in this advisory's
references) explicitly specifies the Hex range: introduced in 2.0.0-pre.1,
fixed in 2.19.0. hex.pm confirms 2.19.0 was published on 2026-07-28. The
advisory description itself also states: "This issue affects cowlib: from
2.0.0 before 2.19.0."
Also adds the upstream source code location, confirmed by the fix commit
already present in the references.
