CVE-2019-9512 5 Apache, Apple, Canonical and 2 more 6 Traffic Server, Mac Os X, Swiftnio and 3 more 2026-06-17 7.8 HIGH 7.5 HIGH
Some HTTP/2 implementations are vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2026-06-17 7.8 HIGH 7.5 HIGH
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 and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-5739 2 Nodejs, Opensuse 2 Node.js, Leap 2026-06-17 5.0 MEDIUM 7.5 HIGH
Keep-alive HTTP and HTTPS connections can remain open and inactive for up to 2 minutes in Node.js 6.16.0 and earlier. Node.js 8.0.0 introduced a dedicated server.keepAliveTimeout which defaults to 5 seconds. The behavior in Node.js 6.16.0 and earlier is a potential Denial of Service (DoS) attack vector. Node.js 6.17.0 introduces server.keepAliveTimeout and the 5-second default.
CVE-2019-5737 2 Nodejs, Opensuse 2 Node.js, Leap 2026-06-17 5.0 MEDIUM 7.5 HIGH
In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1.
CVE-2019-1559 13 Canonical, Debian, F5 and 10 more 90 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 87 more 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
CVE-2019-15606 5 Debian, Nodejs, Opensuse and 2 more 7 Debian Linux, Node.js, Leap and 4 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
Including trailing white space in HTTP header values in Nodejs 10, 12, and 13 causes bypass of authorization based on header value comparisons
CVE-2019-15605 6 Debian, Fedoraproject, Nodejs and 3 more 13 Debian Linux, Fedora, Node.js and 10 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
HTTP request smuggling in Node.js 10, 12, and 13 causes malicious payload delivery when transfer-encoding is malformed
CVE-2019-15604 5 Debian, Nodejs, Opensuse and 2 more 10 Debian Linux, Node.js, Leap and 7 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
Improper Certificate Validation in Node.js 10, 12, and 13 causes the process to abort when sending a crafted X.509 certificate
CVE-2018-21270 1 Nodejs 1 Node.js 2026-06-17 5.8 MEDIUM 6.5 MEDIUM
Versions less than 0.0.6 of the Node.js stringstream module are vulnerable to an out-of-bounds read because of allocation of uninitialized buffers when a number is passed in the input stream (when using Node.js 4.x).
CVE-2018-1000168 3 Debian, Nghttp2, Nodejs 3 Debian Linux, Nghttp2, Node.js 2026-06-17 5.0 MEDIUM 7.5 HIGH
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.
CVE-2017-3738 3 Debian, Nodejs, Openssl 3 Debian Linux, Node.js, Openssl 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH1024 are considered just feasible, because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be significant. However, for an attack on TLS to be meaningful, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). Note: The impact from this issue is similar to CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL version 1.0.2-1.0.2m and 1.1.0-1.1.0g are affected. Fixed in OpenSSL 1.0.2n. Due to the low severity of this issue we are not issuing a new release of OpenSSL 1.1.0 at this time. The fix will be included in OpenSSL 1.1.0h when it becomes available. The fix is also available in commit e502cc86d in the OpenSSL git repository.
CVE-2017-3732 2 Nodejs, Openssl 2 Node.js, Openssl 2026-06-17 4.3 MEDIUM 5.9 MEDIUM
There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem.
CVE-2017-3731 2 Nodejs, Openssl 2 Node.js, Openssl 2026-06-17 5.0 MEDIUM 7.5 HIGH
If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. For OpenSSL 1.1.0, the crash can be triggered when using CHACHA20/POLY1305; users should upgrade to 1.1.0d. For Openssl 1.0.2, the crash can be triggered when using RC4-MD5; users who have not disabled that algorithm should update to 1.0.2k.
CVE-2017-16024 2 Nodejs, Sync-exec Project 2 Node.js, Sync-exec 2026-06-17 4.0 MEDIUM 6.5 MEDIUM
The sync-exec module is used to simulate child_process.execSync in node versions <0.11.9. Sync-exec uses tmp directories as a buffer before returning values. Other users on the server have read access to the tmp directory, possibly allowing an attacker on the server to obtain confidential information from the buffer/tmp file, while it exists.
CVE-2017-15897 1 Nodejs 1 Node.js 2026-06-17 4.3 MEDIUM 3.1 LOW
Node.js had a bug in versions 8.X and 9.X which caused buffers to not be initialized when the encoding for the fill value did not match the encoding specified. For example, 'Buffer.alloc(0x100, "This is not correctly encoded", "hex");' The buffer implementation was updated such that the buffer will be initialized to all zeros in these cases.
CVE-2017-15896 1 Nodejs 1 Node.js 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Node.js was affected by OpenSSL vulnerability CVE-2017-3737 in regards to the use of SSL_read() due to TLS handshake failure. The result was that an active network attacker could send application data to Node.js using the TLS or HTTP2 modules in a way that bypassed TLS authentication and encryption.
CVE-2017-14849 1 Nodejs 1 Node.js 2026-06-17 5.0 MEDIUM 7.5 HIGH
Node.js 8.5.0 before 8.6.0 allows remote attackers to access unintended files, because a change to ".." handling was incompatible with the pathname validation used by unspecified community modules.
CVE-2017-11499 1 Nodejs 1 Node.js 2026-06-17 5.0 MEDIUM 7.5 HIGH
Node.js v4.0 through v4.8.3, all versions of v5.x, v6.0 through v6.11.0, v7.0 through v7.10.0, and v8.0 through v8.1.3 was susceptible to hash flooding remote DoS attacks as the HashTable seed was constant across a given released version of Node.js. This was a result of building with V8 snapshots enabled by default which caused the initially randomized seed to be overwritten on startup.
CVE-2017-1000381 3 C-ares, C-ares Project, Nodejs 3 C-ares, C-ares, Node.js 2026-06-17 5.0 MEDIUM 7.5 HIGH
The c-ares function `ares_parse_naptr_reply()`, which is used for parsing NAPTR responses, could be triggered to read memory outside of the given input buffer if the passed in DNS response packet was crafted in a particular way.
CVE-2016-9843 10 Apple, Canonical, Debian and 7 more 24 Iphone Os, Mac Os X, Tvos and 21 more 2026-06-17 7.5 HIGH 9.8 CRITICAL
The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving big-endian CRC calculation.
