PT-2026-31622

fast-jwt provides fast JSON Web Token JWT implementation. From 5.0.0 to 6.2.0, a denial-of-service condition exists in fast-jwt when the allowedAud verification option is configured using a regular expression. Because the aud claim is attacker-controlled and the library evaluates it against the...

Addressable has a Regular Expression Denial of Service in Addressable templates

Impact Within the URI template implementation in Addressable, two classes of URI template generate regular expressions vulnerable to catastrophic backtracking: 1. Templates using the explode modifier with any expansion operator e.g., foo, +var, var, /var, .var, ;var, ?var, &var generate patterns...

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...

UBUNTU-CVE-2026-28356

multipart is a fast multipart/form-data parser for python. Prior to 1.2.2, 1.3.1 and 1.4.0-dev, the parseoptionsheader function in multipart.py uses a regular expression with an ambiguous alternation, which can cause exponential backtracking ReDoS when parsing maliciously crafted HTTP or multipar...

CVE-2026-26996

A flaw was found in minimatch. A remote attacker could exploit this Regular Expression Denial of Service ReDoS vulnerability by providing a specially crafted glob pattern. This pattern, containing numerous consecutive wildcard characters, causes excessive processing and exponential backtracking i...

CVE-2026-2327

Versions of the package markdown-it from 13.0.0 and before 14.1.1 are vulnerable to Regular Expression Denial of Service ReDoS due to the use of the regex /+$/ in the linkify function. An attacker can supply a long sequence of characters followed by a non-matching character, which triggers...

CVE-2026-23956 seroval affected by Denial of Service via RegExp serialization

seroval facilitates JS value stringification, including complex structures beyond JSON.stringify capabilities. In versions 0.2.0 through 1.4.0, overriding RegExp serialization with extremely large patterns can exhaust JavaScript runtime memory during deserialization. Additionally, overriding RegE...

CVE-2026-23956

CVE-2026-23956 concerns the seroval JavaScript value-stringification library. A flaw in RegExp serialization during deserialization allows memory exhaustion and, in some cases, Regular Expression Denial of Service (ReDoS). Affected versions are 1.4.0 and below; the issue is fixed in 1.4.1. Public...

seroval affected by Denial of Service via RegExp serialization

Overriding RegExp serialization with extremely large patterns can exhaust JavaScript runtime memory during deserialization. Additionally, overriding RegExp serialization with patterns that trigger catastrophic backtracking can lead to ReDoS Regular Expression Denial of Service. Mitigation: Serova...

EUVD-2026-0800

Anthropic's MCP TypeScript SDK versions up to and including 1.25.1 contain a regular expression denial of service ReDoS vulnerability in the UriTemplate class when processing RFC 6570 exploded array patterns. The dynamically generated regular expression used during URI matching contains nested...
