mapfish-print: Remote Code Injection (RCE) in Dynamic table
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
mapfish-print is a component of MapFish for printing templated cartographic maps. From 3.23.0 to before 3.28.28, 3.30.30, 3.31.22, 3.33.14, and 4.0.3, the attacker can execute arbitrary code in Dynamic table without being authenticated. This vulnerability is fixed in 3.28.28, 3.30.30, 3.31.22, 3.33.14, and 4.0.3.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.mapfish.print:print-lib, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.mapfish.print:print-lib to 3.28.28 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-44672 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-44672 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-44672. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-44672 in your dependencies?
O3 Security finds CVE-2026-44672 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
