OpenClaw Denial of Service Vulnerability (CNVD-2026-15152)

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw has a denial of service hole that can be exploited by attackers to cause regular expression injection and denial of service...

CVE-2026-4867: Inefficient Regular Expression Complexity

Impact: A bad regular expression is generated any time you have three or more parameters within a single segment, separated by something that is not a period .. For example, /:a-:b-:c or /:a-:b-:c-:d. The backtrack protection added in [email protected] only prevents ambiguity for two...

Picomatch 安全漏洞

Picomatch is a fast and accurate Glob pattern matching library written in JavaScript, developed by micromatch. Versions prior to Picomatch 4.0.4, 3.0.2, and 2.3.2 contained security vulnerabilities. These vulnerabilities stemmed from regular expression denial-of-service attacks when processing...

CVE-2026-0967: Inefficient Regular Expression Complexity

A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...

CVE-2026-4923: Inefficient Regular Expression Complexity

Impact: When using multiple wildcards, combined with at least one parameter, a regular expression can be generated that is vulnerable to ReDoS. This backtracking vulnerability requires the second wildcard to be somewhere other than the end of the path. Unsafe examples: /foo-bar-:baz /a-:b-c-:d...

CVE-2026-4926: Uncontrolled Resource Consumption

Impact: A bad regular expression is generated any time you have multiple sequential optional groups curly brace syntax, such as abc:z. The generated regex grows exponentially with the number of groups, causing denial of service. Patches: Fixed in version 8.4.0. Workarounds: Limit the number of...
