Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44317 exists.\n\nAffected packages and fixed versions:\n- github.com/free5gc/pcf (Go): affected all versions; fixed in 1.4.3\n- github.com/free5gc/pcf (Go): affected all versions; fixed in 1.4.3\n- github.com/free5gc/pcf (Go): affected all versions; fixed in 1.4.3\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-2026-44317/ (Markdown: https://insights.sbomify.com/CVE-2026-44317/index.md)","id":"CVE-2026-44317","markdown":"https://insights.sbomify.com/CVE-2026-44317/index.md","name":"CVE-2026-44317","record":{"aliases":["GHSA-wwqh-7jm5-gj7w","GO-2026-5731"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"5G core network","requires_auth":"low_privilege","summary":"An authenticated attacker can crash the free5GC PCF service by sending a specific policy authorization request, causing a denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"free5gc","vendor":"free5gc"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"free5GC is an open-source implementation of the 5G core network. Prior to 4.2.2, free5GC's PCF POST /npcf-policyauthorization/v1/app-sessions handler panics on a single authenticated request whose ascReqData.suppFeat == \"1\" (enabling traffic-routing feature negotiation) and whose medComponents entries supply an afAppId but NO AfRoutReq.
