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...

CVE-2026-33994

Locutus (npm) in parse_str.js is affected by a prototype-pollution vulnerability in versions 2.0.39 through 3.0.24, due to an incomplete fix for CVE-2026-25521. The attack can pollute Object.prototype by overriding RegExp.prototype.test and supplying a crafted query string, bypassing the guard th...

CVE-2026-33671

A flaw was found in Picomatch, a JavaScript glob matcher. This Regular Expression Denial of Service ReDoS vulnerability allows a remote attacker to cause excessive CPU consumption and block the Node.js event loop, leading to a denial of service. This occurs when untrusted users supply crafted...

CVE-2026-33671

Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable to Regular Expression Denial of Service ReDoS when processing crafted extglob patterns. Certain patterns using extglob quantifiers such as + and , especially when combined with overlapping...

CVE-2026-33671 Picomatch has a ReDoS vulnerability via extglob quantifiers

Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable to Regular Expression Denial of Service ReDoS when processing crafted extglob patterns. Certain patterns using extglob quantifiers such as + and , especially when combined with overlapping...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS in route patterns. An attacker can cause resource exhaustion by supplying input with multiple sequential optional groups, leading to excessive computation and denial of service. Workaround This...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS when multiple wildcards are used in combination with at least one parameter. An attacker can cause excessive resource consumption and application unresponsiveness by supplying specially crafted...

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,...

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...

UBUNTU-CVE-2026-4923

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

CVE-2026-4926 affects path-to-regexp where multiple sequential optional groups (e.g., {a}{b}{c}) cause the generated regular expression to grow exponentially, leading to denial of service. Connected sources confirm the impact and provide the remediation: a patch is released in version 8.4.0. Work...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS when including multiple regular expression parameters in a single segment, separated by something that is not a period .. Poor performance will block the event loop and can lead to a DoS. Note:...
