Detailsinfo

A vulnerability, which was classified as critical, has been found in GitroomHQ postiz-app up to 2.25.2. Affected by this issue is some unknown functionality. The manipulation with an unknown input leads to a improper authentication vulnerability. Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Postiz signs its session, invitation and password reset tokens with one shared secret and without any marker of what a token is for. A route that refreshes the credentials of a browser-extension channel signed data taken from the request itself and stored the result where the requesting user can read it back. A user could therefore obtain a validly signed token containing any claims they choose, which the application accepts as a session, as an organization invitation with a chosen role, as a password reset or as an enterprise provisioning token. A second, narrower route that creates team invitations signs extra fields from the request body in the same way.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-115933 since 10/23/2026. The exploitation is known to be easy. The attack may be launched remotely. The technical details are unknown and an exploit is not available.
