CVE-2026-83542Apache OFBiz code injection
CVE-2026-83542 is a code injection in Apache OFBiz, rated critical (9.8 on CVSS 3.1).
Why this priority: Critical, and reachable over the network without an account.
Published · Updated · NVD status: Analyzed
What it is
Input is evaluated as code by the application, so an attacker's code runs inside it.
How it is reached
An attacker can exploit it over the network, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker run commands or code with the privileges of the affected service.
Is it being exploited?
There is no public report of exploitation yet. It can be exploited automatically, at scale. EPSS estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 65% of scored CVEs.
What to do
- Upgrade Apache OFBiz to 24.09.08 or later.
- Until it is patched, keep it off the internet or behind a VPN, allowlist or authenticating proxy.
Description from NVD
Improper Control of Generation of Code ('Code Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote unauthenticated attacker to execute arbitrary code on the server by staging crafted widget XML in a multipart upload and overriding the mainDecoratorLocation used by a manager login route through an anonymous JSON request, causing OFBiz to load the staged XML through its live screen descriptor mechanism and evaluate an unsandboxed Groovy expression while rendering the authentication-failure page. Further validation established the following:
-- The exploit does not require a malformed or incomplete multipart body: a well-formed multipart request that is kept in flight and then allowed to complete normally is sufficient.
-- The screen loader reads the widget XML from a live process file descriptor while the upload is streaming, rather than from any file the attacker persists to disk.
-- The same underlying issue is also reachable through the public, explicitly unauthenticated /sfa/control/editPortalPageColumnWidth route, returning command output directly in an HTTP 200 response — it is not limited to the login-failure rendering path used in the original report.
Users are recommended to upgrade to version 24.09.08, which fixes this issue.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
- Template engines. The flaw sits between untrusted input and code or command execution.
Trust boundaries in play
- Internet-facing entry points. No account is needed. Any instance reachable from outside your perimeter, through a load balancer, gateway, VPN or exposed admin port, is in scope.
- Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.
Questions to answer about your own systems
- Where does Apache OFBiz run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
