CVE-2026-42042

Name of the Vulnerable Software and Affected Versions Axios versions prior to 0.31.1 Axios versions prior to 1.15.1

Description The XSRF token protection logic uses JavaScript truthy/falsy semantics instead of strict boolean comparison for the withXSRFToken config property. When this property is set to any truthy non-boolean value, the same-origin check (isURLSameOrigin) is short-circuited, causing XSRF tokens to be sent to all request targets, including cross-origin servers controlled by an attacker.

Recommendations Update to version 0.31.1 or later. Update to version 1.15.1 or later.
