Prior to 8.5.0, 8.4.1, 8.3.3, 8.2.3, 8.1.4, 8.0.5, 7.13.7, and 7.10.11, Rocket.Chat's CAS login handler forwards the client-supplied options.cas.credentialToken value straight into a MongoDB findOne({_id: ...}) query without any runtime type check. TypeScript's string parameter annotation is erased at runtime, so an unauthenticated attacker can substitute a MongoDB query operator ({\"$gt\": \"\"}, {\"$ne\": null}, etc.)"},"products":[{"@id":"cpe:2.3:a:rocketchat:rocket.chat:*:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:rocketchat:rocket.chat:*:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"No fixed version is published yet; monitor the upstream advisory.","timestamp":"2026-06-24T20:56:44.843Z"}]}
