DescriptionCVE.org

Dolibarr contains an authorization bypass vulnerability in the clonetasks mass action that allows authenticated users with project creation permissions to clone tasks into private projects they are not authorized to access. An inverted boolean condition in the private-project membership check within actions_massactions.inc.php causes the authorization flag to be set for unauthorized users, allowing attackers to supply a user-controlled projectid POST parameter to create task records in any private project.

AnalysisAI

Authorization bypass in Dolibarr ERP/CRM's clonetasks mass action allows authenticated users with project creation permissions to insert task records into private projects they are not authorized to access. An inverted boolean condition in the private-project membership check within actions_massactions.inc.php incorrectly grants authorization to non-members when it should deny them. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with low-privilege project creation permissions within Dolibarr - unauthenticated access is not sufficient. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 4.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) accurately reflects the bounded impact: network-reachable, low complexity, requires authenticated low-privileged access, and results only in limited integrity impact with no confidentiality or availability consequence. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated Dolibarr user with project creation permissions identifies the ID of a private project they are not a member of - discoverable through application enumeration or knowledge of the instance. The attacker submits a crafted clonetasks mass action POST request with the target private project's ID as the projectid parameter, causing Dolibarr to incorrectly authorize the action due to the inverted membership check and clone tasks into the restricted project. …
Remediation The primary fix is to apply the upstream patch available at https://github.com/Dolibarr/dolibarr/commit/1730aa56675b31cfede895fdae55b673d887fb8f, which corrects the inverted boolean condition in actions_massactions.inc.php. … Detailed patch versions, workarounds, and compensating controls in full report.
