Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths

Summary app.mount strips the mount prefix from the incoming request path using the raw URL pathname, while route matching is performed against the percent-decoded path. This inconsistency causes the prefix to be stripped at the wrong position when the path contains percent-encoded multi-byte...

CVE-2026-47676

Summary: In Hono, prior to 4.12.21, app.mount() strips the mount prefix from the raw URL pathname while route matching uses the percent-decoded path. This mismatch can cause the prefix to be stripped at the wrong position for percent-encoded multi-byte characters, causing the mounted sub-applicat...

CVE-2026-42274

Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version 0.17.14, Heimdall performs rule matching on the raw non-normalized request path, while downstream components may normalize dot-segments according to RFC 3986, Section 6.2.2.3. This discrepancy ca...

CVE-2026-42274 Heimdall: Authorization bypass via path normalization mismatch

Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version 0.17.14, Heimdall performs rule matching on the raw non-normalized request path, while downstream components may normalize dot-segments according to RFC 3986, Section 6.2.2.3. This discrepancy ca...

GHSA-RFGQ-WGG8-662P S3-Proxy has Security Issues in its Resource Path Matching Implementation

Background The original concern is functional: a resource pattern should treat a percent-encoded segment like some%2Fvalue as a single opaque token rather than splitting it into two path segments at the decoded /. Investigation into why %2F was being decoded and how routes matched against the...

CVE-2026-40912 Traefik: StripPrefixRegex auth bypass via Path/RawPath desync

Traefik is an HTTP reverse proxy and load balancer. Prior to versions 2.11.43, 3.6.14, and 3.7.0-rc.2, there is a high severity authentication bypass vulnerability in Traefik's StripPrefixRegex middleware when used in combination with ForwardAuth, BasicAuth, or DigestAuth. The middleware matches...

Rack:: Static header_rules bypass via URL-encoded paths

Summary Rack::Staticapplicablerules evaluates several headerrules types against the raw URL-encoded PATHINFO, while the underlying file-serving path is decoded before the file is served. As a result, a request for a URL-encoded variant of a static path can serve the same file without the headers...
