Kerentanan Use of Cache Containing Sensitive Information. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.

Deskripsi (NVD)

http-cache-semantics through 4.2.0 fails to properly validate security-zeroed cache entries when processing client max-stale directives, allowing unauthenticated attackers to retrieve cached responses belonging to other users. Attackers can request the same URL with a large max-stale value to obtain another user's Set-Cookie session credentials from shared-cache entries that were deliberately zeroed for security reasons.
