An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-61741 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.http4s:http4s-scala-xml_2.13 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_2.13 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_2.13 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M39\n- org.http4s:http4s-scala-xml_2.13 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M39\n- org.http4s:http4s-scala-xml_2.12 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_2.12 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_3 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_3 (Maven): affected all versions; fixed in 0.24.1\n- org.http4s:http4s-scala-xml_3 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M39\n- org.http4s:http4s-scala-xml_3 (Maven): affected from 1.0.0-M1; fixed in 1.0.0-M39\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-2026-61741/ (Markdown: https://insights.sbomify.com/CVE-2026-61741/index.md)","id":"CVE-2026-61741","markdown":"https://insights.sbomify.com/CVE-2026-61741/index.md","name":"CVE-2026-61741","record":{"aliases":["GHSA-cjx3-73hr-rpw7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Scala XML library","requires_auth":"none","summary":"Attackers can exploit unconfigured XML parsers in http4s-scala-xml to read local files, perform SSRF, or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"http4s-scala-xml provides `EntityDecoder[F, scala.xml.Elem]` instances that parse XML message bodies. Prior to versions 0.24.1 and 1.0.0-M39, these decoders used a `javax.xml.parsers.SAXParserFactory` obtained from `SAXParserFactory.newInstance` without any security configuration.  With the JDK's default settings, the parser resolves DOCTYPE declarations, external general and parameter entities, and external DTDs.An application that uses these decoders to parse untrusted XML is vulnerable to XML External Entity (XXE) attacks.  An attacker can craft a request that discloses local files readable by the service process, performs server-side request forgery (SSRF) against internal network resources, and/or causes denial of service through entity expansion.
