Ech0: ParseAcceptLanguage `_` separator bypass enables ~70x CPU amplification via Accept-Language header in i18n.Middleware

Summary Ech0's i18n middleware runs on every HTTP request and constructs a fresh goi18n.Localizer from the raw Accept-Language header without imposing any size or shape filter. goi18n.NewLocalizer calls golang.org/x/text/language.ParseAcceptLanguage on the value internally. The underlying parser...

CVE-2026-44242

Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. Prior to 4.10.22, the bundleCache is keyed by Locale, baseName where the locale originates from the HTTP Accept-Language header. In applications that explicitly register a...

Astra Linux – Vulnerability in Python-Django

In Django 3.2 before 3.2.17, 4.0 before 4.0.9, and 4.1 before 4.1.6, the parsed values of the Accept-Language header are cached in order to avoid repeated parsing. This can lead to a potential denial-of-service vulnerability due to excessive memory usage if the raw value of the Accept-Language...

Astra Linux – Vulnerability in golang-golang-x-text

An attacker can cause a denial of service by creating an Accept-Language header that requires ParseAcceptLanguage to take significant time to process...

Astra Linux – Vulnerability in golang-golang-x-text

In Go 1.15.4, a "index out of range" panic occurs in the language.ParseAcceptLanguage function during the parsing of the -u- extension. The language.ParseAcceptLanguage function is supposed to be able to parse an HTTP Accept-Language header...
