Feb 12, 2026ntpd-rs is a full-featured implementation of the Network Time Protocol.CVE-2026-26076 · Other software · pendulum-project · reported by GitHubMedium 6.9
ntpd-rs is a full-featured implementation of the Network Time Protocol. Prior to 1.7.1, an attacker can remotely induce moderate increases (2-4 times above normal) in cpu usage. When having NTS enabled on an ntpd-rs server, an attacker can create malformed NTS packets that take significantly more effort for the server to respond to by requesting a large number of cookies. This can lead to degraded server performance even when a server could otherwise handle the load. This vulnerability is fixed in 1.7.1.

Aug 29, 2025nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols.CVE-2025-58066 · Other software · pendulum-project · reported by GitHubMedium 5.3
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. In versions between 1.2.0 and 1.6.1 inclusive servers which allow non-NTS traffic are affected by a denial of service vulnerability, where an attacker can induce a message storm between two NTP servers running ntpd-rs. Client-only configurations are not affected. Affected users are recommended to upgrade to version 1.6.2 as soon as possible.

Jun 28, 2024nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols.CVE-2024-38528 · Other software · pendulum-project · reported by GitHubHigh 7.5
nptd-rs is a tool for synchronizing your computer's clock, implementing the NTP and NTS protocols. There is a missing limit for accepted NTS-KE connections. This allows an unauthenticated remote attacker to crash ntpd-rs when an NTS-KE server is configured. Non NTS-KE server configurations, such as the default ntpd-rs configuration, are unaffected. This vulnerability has been patched in version 1.1.3.

May 27, 2023ntpd-rs is an NTP implementation written in Rust.CVE-2023-33192 · Other software · pendulum-project · reported by GitHubHigh 7.5
ntpd-rs is an NTP implementation written in Rust. ntpd-rs does not validate the length of NTS cookies in received NTP packets to the server. An attacker can crash the server by sending a specially crafted NTP packet containing a cookie shorter than what the server expects. The server also crashes when it is not configured to handle NTS packets. The issue was caused by improper slice indexing. The indexing operations were replaced by safer alternatives that do not crash the ntpd-rs server process but instead properly handle the error condition. A patch was released in version 0.3.3.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
