CVE-2026-81729 — Dolibarr before 23.0.4 Incorrect Authorization on REST API Document Deletion

Dolibarr before 23.0.4 authorizes REST API document deletion against the wrong permission. Documents::delete() in htdocs/api/class/api_documents.class.php calls dol_check_secure_access_document() with the mode argument 'read' when handling DELETE /api/index.php/documents, while the sibling builddoc() path passes 'write', the correct mode for an operation that modifies stored data. An authenticated API user who holds only a read permission for a document-bearing module, for example societe:lire or facture:lire, and no create, write, delete or admin permission, therefore passes the check and can permanently delete that module's documents: third-party files, invoices, orders, proposals, project files and generated PDFs, with no recovery path. The call site is htdocs/api/class/api_documents.class.php:1276 in 23.0.3 and passes 'write' from 23.0.4 onward.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

Technical severity (medium)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Dolibarr Dolibarr, Dolibarr Dolibarr Erp/crm).
Apply the fixed version or the patch documented under Remediation.
Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
