An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55864 exists.\n\nAffected packages and fixed versions:\n- org.geonetwork-opensource:gn-web-app (Maven): affected from 4.0.0; fixed in 4.2.17\n- org.geonetwork-opensource:gn-web-app (Maven): affected from 4.0.0; fixed in 4.2.17\n- org.geonetwork-opensource:gn-web-app (Maven): affected from 4.4.0; fixed in 4.4.12\n- org.geonetwork-opensource:gn-web-app (Maven): affected from 4.4.0; fixed in 4.4.12\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-55864/ (Markdown: https://insights.sbomify.com/CVE-2026-55864/index.md)","id":"CVE-2026-55864","markdown":"https://insights.sbomify.com/CVE-2026-55864/index.md","name":"CVE-2026-55864","record":{"aliases":["GHSA-5hx7-j24v-rffj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"GeoNetwork catalog application","requires_auth":"none","summary":"An anonymous attacker can exploit an SSRF vulnerability in the SLD tool to access internal network resources and disclose sensitive data.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"GeoNetwork is a catalog application to manage spatially referenced resources. Prior to 4.2.17 and 4.4.12, POST /api/tools/ogc/sld accepted a caller-supplied WMS server URL and performed a server-side HTTP GET without destination validation. An anonymous attacker could make the GeoNetwork server send requests to internal hosts that are not publicly reachable. When the outbound response was XML, the endpoint could store and return the fetched body, making the request forgery non-blind and enabling internal data disclosure, authorization bypass, and network reconnaissance.
