CVE-2020-27720 1 F5 2 Big-ip Carrier-grade Nat, Big-ip Local Traffic Manager 2026-06-17 4.3 MEDIUM 7.5 HIGH
On BIG-IP LTM/CGNAT version 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.3, and 13.1.0-13.1.3.5, when processing NAT66 traffic with Port Block Allocation (PBA) mode and SP-DAG enabled, and dag-ipv6-prefix-len configured with a value less than the default of 128, an undisclosed traffic pattern may cause the Traffic Management Microkernel (TMM) to restart.
CVE-2020-27719 1 F5 14 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Advanced Web Application Firewall and 11 more 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
On BIG-IP 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, and 14.1.0-14.1.3, a cross-site scripting (XSS) vulnerability exists in an undisclosed page of the BIG-IP Configuration utility.
CVE-2020-27718 1 F5 2 Big-ip Advanced Web Application Firewall, Big-ip Application Security Manager 2026-06-17 5.0 MEDIUM 7.5 HIGH
When a BIG-IP ASM or Advanced WAF system running version 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.3, 13.1.0-13.1.3.4, 12.1.0-12.1.5.2, or 11.6.1-11.6.5.2 processes requests with JSON payload, an unusually large number of parameters can cause excessive CPU usage in the BIG-IP ASM bd process.
CVE-2020-27717 1 F5 1 Big-ip Domain Name System 2026-06-17 7.8 HIGH 7.5 HIGH
On BIG-IP DNS 16.0.0-16.0.0.1, 15.1.0-15.1.0.5, 14.1.0-14.1.3, 13.1.0-13.1.3.4, and 12.1.0-12.1.5.2, undisclosed series of DNS requests may cause TMM to restart and generate a core file.

CVE-2020-27715 1 F5 11 Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager, Big-ip Analytics and 8 more 2026-06-17 7.8 HIGH 7.5 HIGH
On BIG-IP 15.1.0-15.1.0.5 and 14.1.0-14.1.3, crafted TLS request to the BIG-IP management interface via port 443 can cause high (~100%) CPU utilization by the httpd daemon.
CVE-2020-27714 1 F5 1 Big-ip Advanced Firewall Manager 2026-06-17 4.3 MEDIUM 7.5 HIGH
On the BIG-IP AFM version 15.1.0-15.1.0.5, 14.1.0-14.1.3, and 13.1.0-13.1.3.5, when a Protocol Inspection Profile is attached to a FastL4 virtual server with the protocol field configured to either Other or All Protocols, the TMM may experience a restart if the profile processes non-TCP traffic.
CVE-2020-27713 1 F5 1 Big-ip Advanced Firewall Manager 2026-06-17 5.0 MEDIUM 7.5 HIGH
In certain configurations on version 13.1.3.4, when a BIG-IP AFM HTTP security profile is applied to a virtual server and the BIG-IP system receives a request with specific characteristics, the connection is reset and the Traffic Management Microkernel (TMM) leaks memory.
CVE-2020-24349 1 F5 1 Njs 2026-06-17 2.1 LOW 5.5 MEDIUM
njs through 0.4.3, used in NGINX, allows control-flow hijack in njs_value_property in njs_value.c. NOTE: the vendor considers the issue to be "fluff" in the NGINX use case because there is no remote attack surface.
CVE-2020-24348 1 F5 1 Njs 2026-06-17 2.1 LOW 5.5 MEDIUM
njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_json_stringify_iterator in njs_json.c.
CVE-2020-24347 1 F5 1 Njs 2026-06-17 2.1 LOW 5.5 MEDIUM
njs through 0.4.3, used in NGINX, has an out-of-bounds read in njs_lvlhsh_level_find in njs_lvlhsh.c.
CVE-2020-24346 1 F5 1 Njs 2026-06-17 6.8 MEDIUM 7.8 HIGH
njs through 0.4.3, used in NGINX, has a use-after-free in njs_json_parse_iterator_call in njs_json.c.
CVE-2020-19695 1 F5 1 Njs 2026-06-17 N/A 9.8 CRITICAL
Buffer Overflow found in Nginx NJS allows a remote attacker to execute arbitrary code via the njs_object_property parameter of the njs/njs_vm.c function.
CVE-2020-19692 1 F5 1 Njs 2026-06-17 N/A 9.8 CRITICAL
Buffer Overflow vulnerabilty found in Nginx NJS v.0feca92 allows a remote attacker to execute arbitrary code via the njs_module_read in the njs_module.c file.
CVE-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2026-06-17 6.8 MEDIUM 6.5 MEDIUM
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 allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
CVE-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2026-06-17 7.8 HIGH 7.5 HIGH
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 is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2026-06-17 7.8 HIGH 7.5 HIGH
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 peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
CVE-2019-9513 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 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 consume excess CPU.
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.
