|---|---|---|---|---|---|---|---|---|
| CVE-2023-44487 | Hig | 0.65 | 7.5 | 1.00 | KEV | Oct 10, 2023 | 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. | |
| CVE-2021-3586 | Cri | 0.64 | 9.8 | 0.01 | Aug 22, 2022 | A flaw was found in servicemesh-operator. The NetworkPolicy resources installed for Maistra do not properly specify which ports may be accessed, allowing access to all ports on these resources from any pod. The highest threat from this vulnerability is to data confidentiality… | ||
| CVE-2020-27846 | Cri | 0.57 | 9.8 | 0.05 | Dec 21, 2020 | A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypass SAML Authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||
| CVE-2019-9515 | Hig | 0.56 | 7.5 | 0.87 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame… | ||
| CVE-2019-9513 | Hig | 0.55 | 7.5 | 0.82 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can… | ||
| CVE-2019-9900 | Hig | 0.54 | 8.3 | 0.04 | Apr 25, 2019 | When parsing HTTP/1.x header values, Envoy 1.9.0 and before does not reject embedded zero characters (NUL, ASCII 0x0). This allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to… | ||
| CVE-2019-9511 | Hig | 0.53 | 7.5 | 0.60 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size… | ||
| CVE-2019-9518 | Hig | 0.51 | 7.5 | 0.25 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE.… | ||
| CVE-2019-9517 | Hig | 0.51 | 7.5 | 0.28 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually… | ||
| CVE-2026-47774 | Hig | 0.49 | 7.5 | 0.01 | Jun 17, 2026 | Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to versions 1.35.11, 1.36.7, 1.37.3, and 1.38.1, a vulnerability in Envoy's HTTP/2 downstream request processing allows an unauthenticated remote client to trigger excessive memory… | ||
| CVE-2020-1764 | Hig | 0.49 | 8.6 | 0.03 | Mar 26, 2020 | A hard-coded cryptographic key vulnerability in the default configuration file was found in Kiali, all versions prior to 1.15.1. A remote attacker could abuse this flaw by creating their own JWT signed tokens and bypass Kiali authentication mechanisms, possibly gaining… | ||
| CVE-2020-8661 | Hig | 0.49 | 7.5 | 0.02 | Mar 4, 2020 | CNCF Envoy through 1.13.0 may consume excessive amounts of memory when responding internally to pipelined requests. | ||
| CVE-2020-8659 | Hig | 0.49 | 7.5 | 0.02 | Mar 4, 2020 | CNCF Envoy through 1.13.0 may consume excessive amounts of memory when proxying HTTP/1.1 requests or responses with many small (i.e. 1 byte) chunks. | ||
| CVE-2020-8595 | Hig | 0.48 | 7.3 | 0.03 | Feb 12, 2020 | Istio versions 1.2.10 (End of Life) and prior, 1.3 through 1.3.7, and 1.4 through 1.4.3 allows authentication bypass. The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting… | ||
| CVE-2019-9514 | Hig | 0.48 | 7.5 | 0.83 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the… | ||
| CVE-2019-9516 | Med | 0.47 | 6.5 | 0.56 | Aug 13, 2019 | Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations… | ||
| CVE-2025-0752 | Hig | 0.46 | 7.1 | 0.00 | Jan 28, 2025 | A flaw was found in OpenShift Service Mesh 2.6.3 and 2.5.6. Rate-limiter avoidance, access-control bypass, CPU and memory exhaustion, and replay attacks may be possible due to improper HTTP header sanitization in Envoy. | ||
| CVE-2020-1704 | Hig | 0.46 | 7.0 | 0.00 | Feb 17, 2020 | An insecure modification vulnerability in the /etc/passwd file was found in all versions of OpenShift ServiceMesh (maistra) before 1.0.8 in the openshift/istio-kialia-rhel7-operator-container. An attacker with access to the container could use this flaw to modify /etc/passwd and… | ||
| CVE-2019-25014 | Med | 0.42 | 6.5 | 0.01 | Jan 29, 2021 | A NULL pointer dereference was found in pkg/proxy/envoy/v2/debug.go getResourceVersion in Istio pilot before 1.5.0-alpha.0. If a particular HTTP GET request is made to the pilot API endpoint, it is possible to cause the Go runtime to panic (resulting in a denial of service to… | ||
| CVE-2020-1762 | Hig | 0.39 | 7.0 | 0.01 | Apr 27, 2020 | An insufficient JWT validation vulnerability was found in Kiali versions 0.4.0 to 1.15.0 and was fixed in Kiali version 1.15.1, wherein a remote attacker could abuse this flaw by stealing a valid JWT cookie and using that to spoof a user session, possibly gaining privileges to… |
