CVE-2026-73846 · CKAN MCP Server: Cache-key canonicalization collision enables cache confusion / poisoning
This page contains facts from public vulnerability sources. Check the original advisory before updating.
CKAN MCP Server is a tool for querying CKAN open data portals. Prior to 0.4.112, canonicalizeParams in src/utils/cache.ts serializes request parameters with unescaped ampersand, equals-sign, and vertical-bar delimiters, allowing different logical parameter sets used by buildCacheKey to collide and an attacker to prime a shared cache with a response for a victim's distinct query. This issue is fixed in version 0.4.112.
