Inefficient regular expression complexity in axios - CVE-2026-44496

Vulnerability identifier: #VU133096

CSH Severity: Medium

CVSS v4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-44496

CWE-ID: CWE-1333

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to inefficient regular expression complexity in lib/helpers/cookies.js read(name) when processing an attacker-controlled XSRF cookie name while reading document.cookie. A remote attacker can supply a crafted cookie name containing regex metacharacters to cause a denial of service.

The issue affects standard browser environments and can freeze the affected browser tab while axios prepares a request. Applications are affected only when attacker-controlled data reaches the XSRF cookie name configuration or an unsafe direct call to the internal cookie helper.
