Users who used to be subscribed to a private stream and have been removed from it since retain the ability to edit messages/topics, move messages to other streams, and delete messages that they used to have access to, if other relevant organization permissions allow these actions. For example, a user may be able to edit or delete their old messages they posted in such a private stream. An administrator will be able to delete old messages (that they had access to) from the private stream. This issue was fixed in Zulip Server version 7.3."}],"source":{"advisory":"GHSA-q3wg-jm9p-35fj","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T15:25:36.357Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/zulip/zulip/security/advisories/GHSA-q3wg-jm9p-35fj","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/zulip/zulip/security/advisories/GHSA-q3wg-jm9p-35fj"},{"name":"https://zulip.readthedocs.io/en/latest/overview/changelog.html#zulip-server-7-3","tags":["x_refsource_MISC","x_transferred"],"url":"https://zulip.readthedocs.io/en/latest/overview/changelog.html#zulip-server-7-3"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-30T18:17:12.677442Z","id":"CVE-2023-32678","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":"2024-09-30T18:17:38.788Z"}}]}}
