CVE-2026-33994

Locutus brings stdlibs of other programming languages to JavaScript for educational purposes. Starting in version 2.0.39 and prior to version 3.0.25, a prototype pollution vulnerability exists in the parsestr function of the npm package locutus. An attacker can pollute Object.prototype by...

GHSA-27V5-C462-WPQ7 path-to-regexp vulnerable to Regular Expression Denial of Service via multiple wildcards

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-2026-0967

CVE-2026-0967 describes a denial-of-service in libssh where an attacker can craft hostnames via client config or known_hosts files that, when processed by match_pattern(), trigger inefficient regular expression backtracking. The result is timeouts and resource exhaustion on the client side. Publi...

CVE-2026-0967

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,...

DEBIAN-CVE-2026-4926

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...
