AnalysisAI

Unauthenticated remote code execution in Mapfish Print (org.mapfish.print) allows attackers to execute arbitrary code via a code injection flaw in the Dynamic table feature. The vulnerability carries a CVSS 4.0 score of 9.3 with network-accessible, low-complexity exploitation requiring no privileges or user interaction. No public exploit identified at time of analysis, though the GHSA advisory and four parallel patched release lines indicate vendor-confirmed severity.

Technical ContextAI

Mapfish Print is a Java-based reporting/printing library and servlet (org.mapfish.print:print-lib and print-servlet, distributed via Maven) used to generate PDF/image reports from web map applications, commonly embedded in GeoServer and OpenLayers/MapFish stacks. The flaw is classified as CWE-94 (Improper Control of Generation of Code, i.e., Code Injection) and resides in the Dynamic table rendering feature, where attacker-controlled input is interpreted as executable code rather than treated as data - typical of expression-language or template injection paths in Java reporting components. The affected packages span four maintained branches (3.28.x, 3.30.x, 3.31.x, 3.33.x), indicating a long-lived defect in the dynamic table code path.

RemediationAI

Vendor-released patches are available; upgrade to 3.28.28, 3.30.30, 3.31.21, or 3.33.14 depending on the branch in use, per the GHSA advisory at https://github.com/mapfish/mapfish-print/security/advisories/GHSA-q7m6-wpvf-mvwx. If patching cannot be performed immediately, restrict network access to the Mapfish Print servlet endpoint (typically /print/*) so it is only reachable from trusted internal application backends rather than the public internet, and disable or remove configurations that expose the Dynamic table feature to user-controlled input - accepting the trade-off that downstream map applications relying on dynamic tables will lose that rendering capability until patched. Audit reverse proxy and WAF rules to block POST bodies containing unexpected expression-language or scripting tokens against the print endpoint as an interim filter, recognizing that template-injection payloads vary and filter bypasses are likely.
