CVE-2024-7246
Last modified
CVE-2024-7246 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. It's possible for a gRPC client communicating with a HTTP/2 proxy to poison the HPACK table between the proxy and the backend such that other clients see failed requests. It's also possible to use this vulnerability to leak other clients HTTP header keys, but not values. This occurs because the error status for a misencoded header is not cleared between header reads, resulting in subsequent (incrementally indexed) added headers in the first request being poisoned until cleared from the HPACK table. Please update to a fixed version of gRPC as soon as possible. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
