Prior to version 5.5.3 #59, collection item operations are vulnerable to authorization flaws, allowing a normal authenticated user to modify another user’s collection items. This affects both add item (/actions/add_to_collection.php) due to missing authorization checks and delete item (/manage_collections.php?mode=manage_items...) due to a broken ownership check in removeItemFromCollection(). As a result, attackers can insert and remove items from collections they do not own. Version 5.5.3 #59 fixes the issue."}],"source":{"advisory":"GHSA-6wf8-rw5f-c9mv","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-02-27T20:23:05.995974Z","id":"CVE-2026-28354","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-02-27T20:23:22.876Z"}}]}}
