VUL-0: CVE-2019-15608: yarn: TOCTOU vulnerability leads to cache pollution
Last modified: 2020-07-02 09:05:51 UTC
The package integrity validation in yarn < 1.19.0 contains a TOCTOU vulnerability where the hash is computed before writing a package to cache. It's not computed again when reading from the cache. This may lead to a cache pollution attack.
Only in TW which ships an already fixed version
