In versions 3.0.1 and prior on the `stable` branch and versions 3.1.0.beta2 and prior on the `beta` and `tests-passed` branches, the count of personal messages displayed for a tag is a count of all personal messages regardless of whether the personal message is visible to a given user. As a result, any users can technically poll a sensitive tag to determine if a new personal message is created even if the user does not have access to the personal message.\n\nIn the patched versions, the count of personal messages tagged with a given tag is hidden by default. To revert to the old behaviour of displaying the count of personal messages for a given tag, an admin may enable the `display_personal_messages_tag_counts` site setting."}],"source":{"advisory":"GHSA-rf8j-mf8c-82v7","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T10:49:07.633Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/discourse/discourse/security/advisories/GHSA-rf8j-mf8c-82v7","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/discourse/discourse/security/advisories/GHSA-rf8j-mf8c-82v7"},{"name":"https://github.com/discourse/discourse/commit/f31f0b70f82c43d93220ce6fc0d4f57440452f37","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/discourse/discourse/commit/f31f0b70f82c43d93220ce6fc0d4f57440452f37"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-02-25T14:29:07.994823Z","id":"CVE-2023-23935","options":[{"Exploitation":"none"},{"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":"2025-02-25T14:54:52.894Z"}}]}}
