Supported Versions

    • Fixed Referer-based bypass in the HTTP port reverse proxy that let attackers reach arbitrary paths on upstream ports
    • Fixed path traversal in the HTTP port reverse proxy via .. / percent-encoded variants escaping the mounted route prefix
    • HTTP port reverse proxy now forwards only an allow-list of request headers to upstreams, preventing header smuggling (Authorization, Cookie, X-Forwarded-*, etc.) to localhost services
    • Added support for modern and HD skins to ClientUtil.drawPlayerFace (moved over from Wawel Auth)
