CVE-2026-67991

crmne/rubyllm at commit fa6f279847d6d7027814539d9c0dfc3bbdfd2a83 contains a polynomial-time regular expression denial-of-service condition in RubyLLM::Utils.underscore on Ruby 3.1.x. A very long crafted class, agent, or tool name can cause excessive CPU consumption and a denial of service...

CVE-2026-60075

A flaw was found in Date::Manip for Perl. An attacker could exploit a vulnerability in the parsetime function by providing a specially crafted input string containing long sequences of whitespace. This could lead to excessive CPU consumption due to inefficient processing, resulting in a Denial of...

PT-2026-71671

Name of the Vulnerable Software and Affected Versions vLLM versions prior to 0.26.0 Description An unauthenticated request to the '/v1/completions' endpoint can cause a denial of service by consuming a CPU core and stalling the structured-output engine path. This occurs because the structured...

Linux Distros Unpatched Vulnerability : CVE-2026-18503

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass...

mime: golang: Golang MIME: Denial of Service via maliciously-crafted MIME header

A flaw was found in the Golang MIME Multipurpose Internet Mail Extensions package. A remote attacker could exploit this vulnerability by sending a maliciously-crafted MIME header containing many invalid encoded-words.
