CVE-2026-77923: Dolibarr Erp/crm

Medium severity, CVSS 4.3. EPSS: 0.4% chance of exploitation in the next 30 days.

Dolibarr 21.0.0 before 24.0.0 contains an authorization bypass vulnerability caused by an inverted boolean condition in the private-project membership check within the clonetasks mass action handler in htdocs/core/actions_massactions.inc.php. Authenticated users with project creation permission but without access to a target private project can exploit the flawed !in_array() check to clone tasks into unauthorized private projects.

Affected products

• Dolibarr Dolibarr Erp/crm: from 21.0.0, before 24.0.0 (fixed in 24.0.0)
