The same happens when the signature part is missing, when the header names an encryption algorithm instead of a signing algorithm, or when the payload is not JSON. Each such request logs an ERROR and raises an alert on the error channel, even though the client is at fault. This traffic comes mostly from scanners, so the noise hides real errors. Authentication is shared, so this affects Approval Path and the other Connect apps that use it.\n\nCause\n\nThe token is parsed only after a database connection is opened. Only a few parse errors were treated as a bad token; everything else was handled as an internal app error.\n\nSteps to reproduce\n\n-\nSend a request to any app endpoint that needs authentication, with jwt=header.payload in the query.\n\nActual behavior\n\nHTTP 500. The log has an ERROR Invalid serialized unsecured/JWS/JWE object: Missing second delimiter.\n\nExpected behavior\n\nHTTP 401 with a WARN log entry. No ERROR and no error channel alert.\n\nOut of scope\n\nOther client errors during authentication still return 500 (e.g. app install with a non-existent key id).\n\nAcceptance criteria\n\n-\nA token without all parts (e.g. header.payload) returns 401.\n\n-\nA token with an encryption algorithm in the header (e.g. RSA-OAEP) returns 401.\n\n-\nA token whose payload is not JSON returns 401.\n\n-\nA malformed token does not use a database connection.\n\n-\nNone of these requests log an ERROR.\n\n-\nRequests with a valid token and requests with no token behave as before.⟦/1e53326e⟧","origin":"issue description"},"fields":[{"id":"priority","name":{"untrusted":"⟦1e53326e⟧Priority⟦/1e53326e⟧","origin":"field name set by a Jira admin"},"value":{"untrusted":"⟦1e53326e⟧Priority: LowestLowest⟦/1e53326e⟧","origin":"field value"}},{"id":"assignee","name":{"untrusted":"⟦1e53326e⟧Assignee⟦/1e53326e⟧","origin":"field name set by a Jira admin"},"value":{"untrusted":"⟦1e53326e⟧Kamil Zarychta⟦/1e53326e⟧","origin":"field value"}},{"id":"reporter","name":{"untrusted":"⟦1e53326e⟧Reporter⟦/1e53326e⟧","origin":"field name set by a Jira admin"},"value":{"untrusted":"⟦1e53326e⟧Kamil Zarychta⟦/1e53326e⟧","origin":"field value"}},{"id":"labels","name":{"untrusted":"⟦1e53326e⟧Labels⟦/1e53326e⟧","origin":"field name set by a Jira admin"},"value":{"untrusted":"⟦1e53326e⟧release_notes_worthyroadmap⟦/1e53326e⟧","origin":"field value"}},{"id":"timetracking","name":{"untrusted":"⟦1e53326e⟧Time tracking⟦/1e53326e⟧","origin":"field name set by a Jira admin"},"value":{"untrusted":"⟦1e53326e⟧40m logged⟦/1e53326e⟧","origin":"field value"}}],"attachments":[],"comments":{"total":0,"items":[]}}},"actions":[],"unavailableActions":[],"reminder":"End of data.
