Not enough EPSS history yet.
A small WS-Policy document using repeated policy references can force Neethi to re-expand the same references exponentially during normalization, consuming huge amounts of CPU and memory (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.

CVE-2026-616297.5 HIG—
——0nginx ignition is a user interface for the nginx web server. In versions 2.29.0 through 2.40.0, the gin i18n middleware in nginx-ignition's API server runs in front of every HTTP request and calls `golang.org/x/text/language.ParseAcceptLanguage` on the raw `Accept-Language` header without imposing any size or shape filter. The underlying parser has quadratic-time behaviour on long lists of malformed language tags. The CVE-2022-32149 guard that golang.org/x/text added in v0.3.8 caps the number of `-` characters in the input at 1000, but it does not cap `_` characters even though the parser's internal scanner aliases `_` to `-` before parsing. A single unauthenticated GET request with an `Accept-Language` header built out of `_` separators burns about 2.4 seconds of server CPU on the host running nginx-ignition; ten concurrent attackers saturate a ten-core box for the duration of the attack while consuming ~10 MiB/s of upstream bandwidth. Version 2.40.1 fixes this issue.7hCVE-2026-852203.7 LOW—
——0A vulnerability in the Thinkst Canary honeypot Redis service allows an unauthenticated remote attacker to execute a Denial-of-Service attack against the honeypot.
The vulnerability is accessible when the Redis service is enabled only.
The Canary is NOT affected if the Redis service is disabled.
Thinkst has addressed this issue on all supported platforms.
New update files to address this issue are available on all platforms except Docker. For Docker customers, a new Docker image has been published which includes the patch. Customers with automatic updates enabled already have updates in distribution. If automatic updates are disabled, customers are advised to update their Canaries.
Workarounds are available for customers unable to update at this time.7hCVE-2026-918667.5 HIG—
——0A specially crafted pair of WS-Policy documents can force Neethi's policy-intersection to do exponential amounts of work, pinning the CPU for a long time (denial of service).

——0A specially crafted WS-Policy document can pack unlimited content inside a policy assertion, which Neethi copies into memory without counting it against its size limits, exhausting the heap (denial of service).

——0github.com/temporalio/ringpop-go enforces configured LabelOptions limits when an application changes the local node's labels, but affected versions do not apply those limits to label maps received in SWIM membership changes. A network peer that can reach a live Ringpop TChannel listener can repeatedly submit changes for distinct member addresses containing label keys, values, or counts that exceed the receiver's configured limits. Accepted labels are retained in the member list and disseminated to peers, allowing memory and gossip-bandwidth consumption to exceed configured bounds and potentially making the hosting process unavailable. The fix validates peer-supplied label maps before they are retained or disseminated. Availability only; no confidentiality or integrity impact was identified.6hCVE-2026-572277.5 HIG33.6%
——10Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 7.0.0 until 7.0.17 and 8.0.6, the MQTT parser in rust/src/mqtt/mqtt.rs permits repeated PUBREC or PUBREL messages to be appended to one transaction without a limit. Crafted MQTT traffic can grow transaction state indefinitely, consuming CPU and memory and causing slowdown or denial of service. This issue is fixed in versions 8.0.6 and 7.0.17.3d
