CVE-2026-119800 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 4.3 (medium) and affects ryot; fixed in 10.5.6.

## Summary

Ryot, a self-hosted personal tracking application, lets any logged-in user who knows another collection's ID read that collection's owner identity, name and description, reviews, and full item list. An attacker reaches this remotely over the network with an ordinary account and needs no action from the victim.

## Affected

- IgnisDa ryot: fixed in 10.5.6

## Description

Ryot is a self-hosted personal tracking application. Prior to 10.5.6, the collectionContents GraphQL query implemented by collection_contents() in crates/services/collection/src/content_operations.rs accepts a caller-controlled CollectionContentsInput.collection_id and returns a collection without checking whether the authenticated user owns it, collaborates on it, or may view it. The caller's user id is used only to annotate the response, allowing any authenticated user who obtains another collection's id to read the owner's identity, collection name and description, reviews, and complete item list across the tenant boundary. This issue is fixed in version 10.5.6.
