The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowed clients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and...

Partial String Comparison

Overview @grpc/grpc-js-xds is a Plugin for @grpc/grpc-js. Adds the xds:// URL scheme and associated features. Affected versions of this package are vulnerable to Partial String Comparison via the PathExactValueMatcher.apply method in matcher.ts, where the case-insensitive exact path match...

@grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches

Impact When using RBAC to apply authentication rules, the exact path method name matcher applies a prefix match instead of an exact match for case-insensitive matches. As a result, if a service has a method with a name that is a prefix of the name of a different method, and they have different...

@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.13.1 and 1.14.1, the exact path method name matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. If one service...

CVE-2026-101914

The @grpc/grpc-js library (versions prior to 1.13.1 and 1.14.1 ) contains an authorization flaw where the exact path matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. This allows a request for a longer service method nam...

Grav: Origin validation bypass in Uri::referrer() and Pages::referrerRoute() via unanchored prefix match

Summary Grav\Common\Uri::referrer and Grav\Common\Page\Pages::referrerRoute both check whether an incoming request's Referer header "came from our site" using strstartswith$referrer, $base, where $base is the site's own absolute root URL for example https://example.com, no trailing slash.
