Perplexica's Title Matches Need an Authentication Check Before They Become a Search Inventory
Perplexica is an open-source AI search interface. A ZoomEye count-only probe on November 15, 2026 returned no app="Perplexica" matches, 586 title="Perplexica" matches, and 662 http.body="Perplexica" matches. The queries used sub_type=all, page 1, and page size 1.
The title and body counts are close, which can invite a false sense of precision. Both are textual observations. A deployment page, a project fork, a documentation site, and a live search interface can all carry the name. The absent application fingerprint means the engine did not identify the app signature for this query; it does not mean no instance exists.
The search service has multiple authorities
An AI search interface combines a web search source, a model provider, prompt construction, and a conversation state. The public page may only expose the question box, while the server holds API credentials for search and model services. Review those credentials as separate assets.
If the service is intended for a trusted team, put authentication in front of the search endpoint and the administration paths. A public demo can be acceptable when it has its own budget, rate limits, and a clear statement that questions are not private. A private deployment should not inherit the demo's access model.
Watch outbound network policy. A search tool can fetch URLs as part of answering a question. That behavior may create server-side request forgery risk if the destination is not controlled. Restrict which search backends and model endpoints the application can reach, and keep provider keys out of client-side code.
Separate content from configuration
The product repository is the best place to confirm supported deployment and configuration. Do not infer a live deployment from a title alone. A matching title might be a fork's README on a code-hosting page. Confirm that the response contains an application interface and that the service has a real request path.
For a confirmed instance, record whether authentication is enabled, which search engine and model are configured, whether sessions are stored, and how long queries and answers are retained. A generic search service can expose user interests even when it does not store a user account.
Rate limiting should apply to questions, model calls, and outbound fetch attempts. A single expensive query can consume provider budget or tie up a worker. Add per-IP and per-user limits where identity exists, and a global concurrency cap where identity does not.
Treat the count as a lead
The 586 title and 662 body matches are close enough to compare, but they should not be added together. The same host may appear in both, and a documentation page may account for many body hits. Keep the exact dorks and timestamps with the finding.
Start with title matches that return a search page. Filter out repositories and documentation by checking the final URL and response type. If the service has a login prompt, record the authentication method and avoid testing credentials. Ask the owner whether the instance is a demo, a team tool, or a public service.
Monitor changes around known deployment domains. A new title match can indicate a migration. It can also be a status page that copied the product name. A missing match can reflect a response change rather than a shutdown.
What a defender should verify
Check authentication on the search endpoint, model and search-provider keys, outbound destination policy, query retention, rate limits, and administrative access. Confirm that the application does not expose a debug endpoint that reveals environment variables or provider credentials.
The 0 application count is a limitation of this measurement, not a conclusion about the population. The useful output is a verified list of search interfaces, their owner, and the data and provider authority behind each endpoint.
