Description

The vulnerability allows a remote attacker to poison browser cache.

The vulnerability exists due to the fetch() API and navigation incorrectly share the same cache, as the cache key does not include the optional headers the fetch() API may contain. A remote attacker can poison the local browser cache by priming it with a fetch() response controlled by the additional headers. Upon navigation to the same URL, the user would see the cached response instead of the expected response.

Mitigation
Install updates from vendor's website.
