Prior to version 1.8.214, the undo-send route `GET /conversation/undo-reply/{thread_id}` checks only whether the current user can view the parent conversation. It does not verify that the current user created the reply being undone. In a shared mailbox, one agent can therefore recall another agent's just-sent reply during the 15-second undo window. Version 1.8.214 fixes the vulnerability.","state":"PUBLISHED","assigner":"GitHub_M","published_at":"2026-04-21 17:16:57","updated_at":"2026-04-21 17:16:57"},"problem_types":["CWE-862","CWE-862 CWE-862: Missing Authorization"],"metrics":[{"version":"3.1","source":"security-advisories@github.com","type":"Secondary","score":"5.9","severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L","baseScore":5.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"LOW"}},{"version":"3.1","source":"CNA","type":"DECLARED","score":"5.9","severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L","data":{"attackComplexity":"HIGH","attackVector":"NETWORK","availabilityImpact":"LOW","baseScore":5.9,"baseSeverity":"MEDIUM","confidentialityImpact":"NONE","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L","version":"3.1"}}],"references":[{"url":"https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-674v-r6xp-mvp6","name":"https://github.com/freescout-help-desk/freescout/security/advisories/GHSA-674v-r6xp-mvp6","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://github.com/freescout-help-desk/freescout/releases/tag/1.8.214","name":"https://github.com/freescout-help-desk/freescout/releases/tag/1.8.214","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://github.com/freescout-help-desk/freescout/commit/c779afdda86fa00a4b85779e034bbfd9ce20c76d","name":"https://github.com/freescout-help-desk/freescout/commit/c779afdda86fa00a4b85779e034bbfd9ce20c76d","refsource":"security-advisories@github.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-40592","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40592","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"freescout-help-desk","product":"freescout","version":"affected < 1.8.214","platforms":[]}],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"product":"freescout","vendor":"freescout-help-desk","versions":[{"status":"affected","version":"< 1.8.214"}]}],"descriptions":[{"lang":"en","value":"FreeScout is a free self-hosted help desk and shared mailbox.
