Overview
Affected versions of this package are vulnerable to Improper Protection of Alternate Path through the TikaServerConfig endpoint gating in the server configuration and request-handling code. An attacker can reach disabled server-side config and pipe-related paths by sending requests to the /config family or by selecting /pipes or /async in a deployed server that exposes them without the intended opt-in. This lets the attacker invoke alternate request-processing paths that should be restricted, which can expose server behavior and permit unintended parsing or processing through those endpoints.
