Twenty is an open-source CRM platform with a vulnerability in versions from 1.20.10 up to but not including 2.7.0. The /metadata GraphQL connectedAccounts query exposed plaintext IMAP, SMTP, and CalDAV passwords of connected accounts to any workspace member due to insufficient access controls. This allowed unauthorized users to retrieve other members' external-service credentials. Workspaces using only Google and Microsoft OAuth were not affected. The issue is fixed in version 2.7.0.
Twenty is an open-source CRM (customer relationship management) platform. Prior to 2.22.0, field-level read permission is enforced on selected output fields but not on GraphQL or REST filter predicates. A workspace member or API key with permission to read an object but not a particular field can reference that denied field in direct filters, relation filters, or persisted view filters. The resulting totalCount and row presence reveal whether guesses match the real column, forming a boolean/count oracle that can reconstruct denied field values for records exposed by the principal's row-level policy. This issue is fixed in version 2.22.0.
Twenty before 2.35.0 fails to validate field and row permissions in the groupBy-with-records GraphQL resolver, allowing authenticated users to bypass permission checks. Attackers with canReadObjectRecords permission but canReadFieldValue false can retrieve restricted field values through the groupBy resolver that would normally be denied.
Twenty through 2.35.0 contains an open redirect vulnerability in the OAuthPropagatorController.propagateOAuthCallback endpoint that treats the state query parameter as a redirect URL. Attackers can craft malicious requests to redirect users to arbitrary hosts while forwarding OAuth authorization codes, bypassing domain validation when IS_MULTIWORKSPACE_ENABLED is disabled.
Twenty is an open-source CRM (customer relationship management) platform. Prior to 2.15.0, Twenty allowed a workspace administrator with the DATA_MODEL permission to supply settings.asExpression for the system TS_VECTOR field searchVector through PATCH /rest/metadata/fields/:id or the updateOneField GraphQL mutation, causing buildSqlColumnDefinition in packages/twenty-server/src/engine/twenty-orm/workspace-schema-manager/utils/build-sql-column-definition.util.ts to concatenate unescaped input into GENERATED ALWAYS AS (...) and execute arbitrary PostgreSQL statements as the application database user. This issue is fixed in version 2.15.0.
Twenty is an open-source CRM (customer relationship management) platform. Prior to 2.9.0, Twenty was vulnerable to a cross-workspace insecure direct object reference (IDOR) in the AI agent monitor's AgentTurnResolver, in packages/twenty-server/src/engine/metadata-modules/ai/ai-agent-monitor/reso lvers/agent-turn.resolver.ts. The agentTurns(agentId) query and the evaluateAgentTurn(turnId) mutation looked up rows by agentId or id only; although AgentTurnEntity has a workspaceId column, it was not included in the WHERE clause, and the class-level guards only checked that the caller was authenticated in some workspace rather than that the requested object belonged to it, with the same flaw present in agent-turn-grader.service.ts. As a result, any authenticated user with the AI settings flag, a workspace owner by default, could target any other workspace on the same instance given the victim's agentId or turnId: agentTurns returned the victim's full chat history including message parts such as raw chat text, tool calls, and tool outputs, while evaluateAgentTurn inserted an agentTurnEvaluation row with the victim's workspaceId and fed the victim's turn into the default LLM. The agentId and turnId are non-guessable UUIDs but are exposed in the URL of the settings page. This issue is fixed in version 2.9.0.
Twenty is an open source CRM. From 1.7.7 through 1.16.7, a critical Remote Code Execution (RCE) vulnerability exists in Twenty CRM via a chained SQL Injection and PostgreSQL COPY TO PROGRAM attack. If Postgres user is a super user then any authenticated user can execute arbitrary OS commands on the database server by injecting SQL through the unsanitized timeZone parameter in the REST API groupBy endpoint. The timeZone field within the group_by query parameter is directly interpolated into a raw SQL expression using JavaScript template literals without any parameterization, validation, or escaping. This affects engine/api/graphql/graphql-query-runner/group-by/resolvers/utils/get-group-by-expression.util.ts.
CVE-2026-44729 is a high-severity cross-site scripting (XSS) vulnerability in the open source CRM Twenty (version 1.18.0 and earlier). The issue arises because the file serving endpoints do not set Content-Type, Content-Disposition, or X-Content-Type-Options headers when serving uploaded files. This allows an authenticated attacker to upload a malicious HTML file containing JavaScript, which executes in the context of the victim's browser when accessed. Exploitation can lead to session hijacking, account takeover, and data theft.
CVE-2026-33975 is a high-severity Server-Side Request Forgery (SSRF) vulnerability in the open source CRM twenty (version 1.18.0 and earlier). The vulnerability arises because the SSRF protection in twenty-server's SecureHttpClientService can be bypassed using IPv4-mapped IPv6 address literals. Node.js normalizes these addresses to a hex form that the SSRF protection does not recognize, allowing an authenticated user to access internal IP addresses, including cloud metadata endpoints, potentially exfiltrating sensitive credentials such as IAM keys. No official patch or remediation guidance is currently available from the vendor.
Twenty is an open source CRM. Prior to 1.20.6, a Stored Cross-Site Scripting (XSS) vulnerability exists in the BlockNote editor component. Due to a lack of protocol validation in the FileBlock component and insufficient server-side inspection of block content, an attacker can inject a javascript: URI into the url property of a file block. This allows the execution of arbitrary JavaScript when a user clicks on the malicious file attachment. This vulnerability is fixed in 1.20.6.
Twenty is an open source CRM. Prior to version 1.18, the SSRF protection in SecureHttpClientService validated request URLs at the request level but did not validate redirect targets. An authenticated user who could control outbound request URLs (e.g., webhook endpoints, image URLs) could bypass private IP blocking by redirecting through an attacker-controlled server. This issue has been patched in version 1.18.
