Exploitation Conditions

The available description is a single-line title from a bulk advisory and does not state the triggering request, endpoint, or configuration. Based on that title, exploitation requires access to the content-permission functionality and abuses a missing authorization check so that a caller can assign the content OWNER role to their own account rather than being restricted to roles they are entitled to grant. The limiting factor is that the attacker appears to need an existing foothold/account on the OFBiz instance to perform the self-grant (inferred from 'self-grant', not confirmed by a CVSS vector), and the instance must be running a version prior to 24.09.08; the exact authorization state required is not confirmed from the available data.

Impact

Key risk signals are largely MISSING for this specific CVE, so confidence is limited. No CVSS vector or score is provided (NVD/vendor list it as N/A), no EPSS exploitation probability is supplied, there is no CISA KEV listing, and no public exploit was identified - the vuln.today Decision label is explicitly 'awaiting_data', signaling that scoring intelligence has not yet been populated. The only hard facts are the vulnerability class (authorization bypass allowing a user to self-grant the content OWNER role), the affected range (all versions prior to Apache OFBiz 24.09.08), and the fix. Contextually, this CVE was disclosed as one entry in a large batch of 40+ OFBiz vulnerabilities, several of which are far more severe (e.g., CVE-2026-68524 pre-authentication RCE and CVE-2026-105330 hard-coded JWT key enabling unauthenticated admin access); relative to those, a privilege-escalation-over-content issue that appears to require an existing account is a lower-tier priority. However, because no CVSS vector is available, the authentication requirement cannot be confirmed from data - the 'self-grant' wording implies a pre-existing session but this is inferred, not vendor-stated. Treat this as a real integrity-affecting authorization flaw to be remediated via the batch upgrade, but not as an isolated emergency on current evidence; the trigger mechanism is not described in the available sources.

Exploit ScenarioDerived

A user who already has access to an Apache OFBiz instance invokes a content-permission operation that fails to check whether the caller is entitled to assign roles, and grants their own account the content OWNER role on content objects they should not control. With OWNER rights they can then read, modify, or administer that content. No public exploit was identified at time of analysis, and the exact trigger is not described in the available sources.

AnalysisAIv1 – Nov 04, 2026

Authorization bypass in Apache OFBiz before 24.09.08 lets an authenticated user who can reach content-permission functionality assign the content OWNER role to their own account, bypassing the intended restriction that they may only grant roles they are entitled to assign. The assessed vector is network-reachable with low privileges and high integrity impact, while confidentiality impact is low and availability impact is none. No public exploit identified at time of analysis and no CISA KEV entry is present in the supplied data; the vendor directs users to upgrade to 24.09.08.

RemediationAI

Upgrade Apache OFBiz to 24.09.08, the version the vendor states addresses these vulnerabilities. The available advisory does not describe a workaround for CVE-2026-81744, so upgrading is the complete remediation listed; verify the deployed version and apply the release from https://ofbiz.apache.org/, using the advisory at https://seclists.org/oss-sec/2026/q4/516 as the change reference. No fixed version other than 24.09.08 is listed in the supplied data.

Technical ContextAI · show details

Apache OFBiz is a Java-based web framework with an entity engine, service engine, and widget-based UI. CVE-2026-81744 appears in the oss-security bulk advisory only as an authorization bypass involving self-granting the content OWNER role; no CWE is provided, and the triggering request, endpoint, or configuration is not described in the available sources. The assessed root cause is a missing authorization check in the content-permission path: a caller can assign OWNER to their own account instead of being limited to roles they are allowed to grant. The assessed CVSS is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N, and the vuln.today priority label is awaiting_data, reflecting limited CVE-specific enrichment. Exact component class or request parameters are not confirmed from the supplied evidence.

Self-granting OWNER implies an existing authenticated account (PR:L) over the network web interface; it yields unauthorized control over content (I:H) with limited read exposure (C:L), low confidence given only a title.

Executive ViewAI

Why It Matters

A critical authorization bypass in Apache OFBiz (CVE-2026-81744) allows any authenticated user with network access to inappropriately elevate their own privileges to content owner, potentially compromising data integrity and access controls. This affects organizations using OFBiz for ERP or e-commerce, requiring immediate attention to prevent insider misuse or unauthorized access.
