CVE-2026-55848: mapfish-print: XXE on MapFish Print allows reading arbitrary files of certain types

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.53% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: org.mapfish:print.print-servlet (Maven) 3.28.30; org.mapfish.print:print-lib (Maven) 3.28.30, 3.30.32, 3.33.16; org.mapfish.print:print-servlet (Maven) 3.30.32, 3.31.24, 3.33.16.

Low priority for now. Upgrade to org.mapfish:print.print-servlet (Maven) 3.28.30; org.mapfish.print:print-lib (Maven) 3.28.30, 3.30.32, 3.33.16; org.mapfish.print:print-servlet (Maven) 3.30.32, 3.31.24, 3.33.16 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

mapfish-print is a component of MapFish for printing templated cartographic maps. Prior to 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5, MapFish Print accepts an attacker-controlled GML layer url in requests to the /api/print3/print endpoint and fetches XML parsed by core/src/main/java/org/mapfish/print/map/geotools/GmlLayer.java without disabling external entities and external DTDs. A remote XML document and DTD can expand a local file entity, and the resulting content can be exposed through the GML parsing and error path. This allows unauthenticated attackers to read files such as operating-system account data, Kubernetes service-account tokens, and certificates. Replacing the file entity target with an internal HTTP endpoint also permits server-side request forgery. This issue is fixed in versions 3.28.30, 3.30.32, 3.31.24, 3.33.16, and 4.0.5.
