It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-22188 exists.\n\nAffected product: Panda3D. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-22188/ (Markdown: https://insights.sbomify.com/CVE-2026-22188/index.md)","id":"CVE-2026-22188","markdown":"https://insights.sbomify.com/CVE-2026-22188/index.md","name":"CVE-2026-22188","record":{"aliases":["GHSA-xvxx-4fr3-55xv"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Panda3D game engine","requires_auth":"none","summary":"Attackers can crash the Panda3D deploy-stub by supplying excessive command-line arguments, causing stack exhaustion and undefined behavior.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"panda3d","vendor":"cmu"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-908","name":"Use of Uninitialized Resource"},{"id":"CWE-789","name":"Memory Allocation with Excessive Size Value"},{"id":"CWE-457","name":"Use of Uninitialized Variable"}],"description":"The deploy-stub component in Panda3D versions up to and including 1.10.16 contains a denial of service vulnerability due to unbounded stack allocation.
