CVE-2026-71511

Dolibarr before 24.0.0 contains a sensitive data exposure vulnerability in the Members REST API that allows authenticated attackers with member-read rights to retrieve bcrypt password verifiers by querying member endpoints. Attackers can call the individual member or member list endpoints to obtain crypted password verifier fields that are not filtered by the base API serializer or the Members API class, potentially enabling offline password cracking attacks.
