Description OSIDB Bzimport 2025-08-21 17:01:42 UTC 
A vulnerability has been found in yarnpkg Yarn up to 1.22.22. This impacts the function setOptions of the file src/util/request-manager.js. Such manipulation leads to inefficient regular expression complexity. Local access is required to approach this attack. This vulnerability only affects products that are no longer supported by the maintainer.

This looks the same as CVE-2025-8262, which was already fixed in yarnpkg-1.22.22-11
