CVE-2026-108500Apache ActiveMQ improper input validation
CVE-2026-108500 is a improper input validation in Apache ActiveMQ, not yet scored.
Why this priority: Not scored yet, and no exploitation signal.
Published · Updated · NVD status: Awaiting Analysis
What it is
The software trusts input it should check, so crafted values reach code that assumes they are well formed.
How it is reached
The record does not say yet how the flaw is reached; the description below is the best guide until it is scored.
What an attacker gains
Its impact has not been scored yet. In practice, this kind of flaw lets an attacker drive the component into behaviour its authors did not intend.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.22% chance of exploitation activity in the next 30 days, higher than 12% of scored CVEs.
What to do
- Upgrade Apache ActiveMQ to a fixed version for your release line (6.3.3, 5.19.12, 6.4.0).
Description from NVD
Input validation vulnerability in Apache ActiveMQ configured to use the LDAPAuthorizationMapPlugin allows an authenticated attacker to create or address a destination with a crafted name containing LDAP DN special characters (such as comma, plus, equals, backslash) can manipulate the LDAP search base used for ACL lookups.
This issue affects Apache ActiveMQ: from 6.3.0 before 6.3.3, from 5.19.0 before 5.19.12.
Users are recommended to upgrade to version 6.4.0, 6.3.3 or 5.19.12, which fixes the 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
- Interfaces that accept external input. The flaw sits at the input boundary of the affected component.
Trust boundaries in play
- At the input boundary of the affected component. An attacker who crosses it can drive the component into behaviour its authors did not intend.
Questions to answer about your own systems
- Where does Apache ActiveMQ run in your systems, and at which version?
- Which of those instances are reachable by people you do not trust?
- What can it reach once compromised: which data stores, secrets and services?
