CVE-2026-105763 twentyhq CVE debrief

Who should care

Defenders responsible for Twenty installations, particularly those with multiple workspace members, should assess exposure and prioritize remediation. They should review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. They should also plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Why it matters

CVE-2026-105763 allows normal workspace members to obtain plaintext IMAP/SMTP/CalDAV passwords of other members, potentially leading to credential misuse and third-party account resets.

• Potential credential misuse for mail or calendar access
• Possible third-party account resets
• Required verification of affected versions and exposure
• Prioritized remediation of vulnerable Twenty installations

Technical summary

The /metadata GraphQL connectedAccounts query in Twenty returned connectionParameters from ConnectedAccountDTO for every connected account in a workspace, including plaintext IMAP, SMTP, and CalDAV passwords, because the field was not hidden and the lookup did not enforce the calling user's identity or account visibility. This issue is fixed in version 2.7.0. Defenders should prioritize verifying exposure and remediating vulnerable Twenty installations. The vulnerability allows normal workspace members to obtain plaintext IMAP/SMTP/CalDAV passwords of other members, potentially leading to credential misuse and third-party account resets.
