labstack/echo v5.4.2

Fixes

• Require a space after the case-insensitive Basic authentication scheme. Malformed schemes such as BasicX no longer reach credential validation or consume AllowedCheckLimit. Valid credentials are still required. #3138, thanks to @Shubham-Padkonde.
• Reject empty cookie tokens and empty client tokens in CSRF validation. This is defense in depth; it does not introduce a new security advisory. #3135, thanks to @hoangtaiki.

Upgrade

go get github.com/labstack/echo/v5@v5.4.2

Go 1.25 remains the module minimum. Build deployments with a supported, patched Go toolchain. No dependencies or public APIs changed in this release.

The security fixes released in v5.4.1 are included unchanged. Their first patched version remains v5.4.1.

Validation: the fixes passed regression tests and upstream race-test and lint checks on Linux, macOS and Windows with Go 1.25, 1.26 and 1.27. The new regressions were also verified to fail without the fixes.
