CVE-2026-119564 in Analytics
Summary
by MITRE • 10/30/2026
Plausible Analytics Community Edition through 3.2.1 contains an information exposure vulnerability that allows site editors to obtain pending invitation and ownership-transfer IDs from the settings/people page. Attackers can register with the invitee's email using the exposed ID and accept it, gaining the invited role or taking site ownership.

The Plausible Analytics Community Edition software through version 3.2.1 contains a critical information exposure vulnerability that compromises the integrity of user management workflows. This flaw resides within the settings interface where administrators manage team members and permissions. Specifically, the application fails to properly obscure or restrict access to pending invitation tokens and ownership transfer identifiers when these elements are rendered on the people management page. Instead of ensuring that such sensitive data is only visible to authorized administrative actions or remains transient during secure transmission, the system exposes these unique identifiers in a manner accessible to any user with editor-level privileges. This design oversight creates a direct pathway for privilege escalation within the application environment.
From a technical perspective, this vulnerability constitutes an insecure direct object reference combined with information leakage. The pending invitation IDs and ownership transfer tokens serve as critical security controls that validate whether a new user is legitimately invited or if site ownership should be transferred to another account. By exposing these identifiers in the client-side interface or through insufficient server-side access control checks on the endpoint serving this data, the application allows any authenticated editor to harvest them. These IDs are typically designed for one-time use and are tied to specific email addresses provided during the invitation process. The lack of proper validation ensures that once an attacker obtains these tokens, they can manipulate the authentication flow intended for legitimate users.
The operational impact of this vulnerability is severe, leading directly to unauthorized privilege escalation and potential complete compromise of the analytics platform's administrative control. An attacker with editor access can exploit the exposed IDs by registering a new account using the email address associated with the pending invitation or ownership transfer request. Upon registration, the system processes the token found in the URL parameters or hidden fields, granting the attacker the role specified in the original invitation or transferring full site ownership to their newly created account. This effectively bypasses all intended access controls and allows an untrusted user to assume the identity of a trusted administrator or team member without requiring password resets or additional authentication factors beyond standard email verification.
This vulnerability aligns with CWE-209, which describes the generation of error messages containing sensitive information that could be exploited by attackers, as well as CWE-639 regarding authorization bypass through URL manipulation if the ID is passed via query parameters. In terms of offensive security frameworks, this behavior maps to MITRE ATT&CK technique T1078, specifically valid accounts and potentially T1548 for abuse of elevation controls. The exploitation path relies on social engineering or internal network access to reach an editor account, followed by the technical extraction of tokens and subsequent registration to hijack privileges.
Mitigation strategies must address both immediate remediation and long-term architectural improvements. For organizations currently running Plausible Analytics Community Edition 3.2.1 or earlier, upgrading to a patched version where this information exposure is resolved is the primary recommendation. In environments where patching is not immediately feasible, administrators should restrict editor-level access to only those users who strictly require it, adhering to the principle of least privilege. Additionally, implementing strict rate limiting on registration endpoints and validating that invitation tokens are consumed in a stateful manner can reduce the window of opportunity for exploitation. Security teams should also audit existing user roles to ensure no unnecessary editors have been granted access to sensitive configuration pages where such data might be exposed until an official patch is applied.
