CVE-2026-44838
RabbitMQ MQTT plugin contains a permission bypass vulnerability: topic-level authorization uses user-supplied client_id substituted into a regex pattern without escaping. From 4.2.0 up to before 4.2.4, an authenticated MQTT user could inject regex operators to bypass topic restrictions. The issue...

GHSA-9GCG-W975-3RJH Istio: AuthorizationPolicy serviceAccounts regex injection via unescaped dots
Impact The serviceAccounts and notServiceAccounts fields in AuthorizationPolicy incorrectly interpret dots . as a regular expression matcher. Because . is a valid character in a service account name, an AuthorizationPolicy ALLOW rule targeting SA e.g. cert-manager.io also matches cert-manager-io,...

SUSE CVE-2026-34830
Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Sendfilemapaccelpath interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not...
GHSA-QV7J-4883-HWH7 Rack::Sendfile header-based X-Accel-Mapping regex injection enables unauthorized X-Accel-Redirect
Summary Rack::Sendfilemapaccelpath interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not escaped, an attacker who can supply X-Accel-Mapping to the backend can inject regex...
