|---|---|---|---|---|---|---|
| CVE-2026-58055 | nghttp2's nghttpx proxy through 1.69.0 forwards an HTTP/1.1 Upgrade request that also carries a Content-Length header and body onto reusable keep-alive backend connections, re-adding the Upgrade and Connection headers while passing Content-Length verbatim. A backend that resolves the resulting ambiguous message in the attacker's favor enables HTTP request/response smuggling and cross-client response-queue poisoning. | [email protected] | 6.3 | 0.20% | 2026-06-27 | 2026-06-27 |
| CVE-2026-40170 | ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted p | [email protected] | 7.5 | 0.58% | 2026-04-16 | 2026-06-17 |
| CVE-2026-27135 | nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. Prior to version 1.68.1, the nghttp2 library stops reading the incoming data when user facing public API `nghttp2_session_terminate_session` or `nghttp2_session_terminate_session2` is called by the application. They might be called internally by the library when it detects the situation that is subject to connection error. Due to the missing internal state validation, the library keeps reading the rest of the data af | [email protected] | 7.5 | 0.56% | 2026-03-18 | 2026-06-17 |
| CVE-2024-28182 | nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability. | [email protected] | 5.3 | 84.96% | 2024-04-04 | 2026-06-17 |
| CVE-2023-44487 KEV | The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | [email protected] | 7.5 | 100.00% | 2023-10-10 | 2026-06-17 |
| CVE-2023-35945 | Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s HTTP/2 codec may leak a header map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames from an upstream server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY` frame skips de-allocation of the bookkeeping structure and pending compressed header. The error return [code path] is taken if connection is already marked for not sending more requests due to ` | [email protected] | 7.5 | 1.11% | 2023-07-13 | 2026-06-17 |
| CVE-2020-11080 | In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame | [email protected] | 3.7 | 5.32% | 2020-06-03 | 2026-06-16 |
| CVE-2016-1544 | nghttp2 before 1.7.1 allows remote attackers to cause a denial of service (memory exhaustion). | [email protected] | 3.3 | 0.89% | 2020-02-06 | 2026-06-16 |
| CVE-2018-1000168 | nghttp2 version >= 1.10.0 and nghttp2 <= v1.31.0 contains an Improper Input Validation CWE-20 vulnerability in ALTSVC frame handling that can result in segmentation fault leading to denial of service. This attack appears to be exploitable via network client. This vulnerability appears to have been fixed in >= 1.31.1. | [email protected] | 7.5 | 10.78% | 2018-05-08 | 2026-06-16 |
| CVE-2015-8659 | The idle stream handling in nghttp2 before 1.6.0 allows attackers to have unspecified impact via unknown vectors, aka a heap-use-after-free bug. | [email protected] | 10.0 | 4.07% | 2016-01-12 | 2026-06-16 |
