RUSTSEC-2026-0373 Missing case-insensitive matching for CSS url function

URL filtering, such as relative URLs and URL scheme limits, is not always applied when CSS sanitization is used. When the inner URL is quoted, CSS url"" is matched case-sensitively, when it should be matched case-insensitively. As a result, while url"" gets the intended domain name filtering, URL...

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...

CVE-2026-87876

This CUPS vulnerability (a follow-up to CVE-2026-27447 ) involves two case-insensitive comparisons on request-derived usernames in scheduler side paths outside the main authorization path—specifically in printer ACL validation and private-attribute filtering . The mismatched case handling could a...
