BIT-NGINX-2026-42533 NGINX Map directive and Regex matching vulnerability

A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and a string expression references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable i...

axios: Axios: Client-side Denial of Service via unescaped regex metacharacters in XSRF cookie name

A flaw was found in Axios. A remote attacker, by influencing the XSRF cookie name in a browser environment, could cause the application to construct a regular expression that leads to excessive processing. This can result in a client-side Denial of Service DoS, where the affected browser tab may...

...

CVE-2026-42533

A flaw was found in NGINX. An unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP requests when the map directive uses regular expression regex matching and references regex capture variables before referencing the map output variable. This can lead to a heap...
