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-2026-22189 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-2026-22189/ (Markdown: https://insights.sbomify.com/CVE-2026-22189/index.md)","id":"CVE-2026-22189","markdown":"https://insights.sbomify.com/CVE-2026-22189/index.md","name":"CVE-2026-22189","record":{"aliases":["GHSA-gwg6-62mc-7h63"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"3D game engine","requires_auth":"none","summary":"Attacker can trigger stack buffer overflow in Panda3D egg-mkfont via long glyph patterns, potentially causing crashes or arbitrary code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains a stack-based buffer overflow vulnerability due to use of an unbounded sprintf() call with attacker-controlled input. When constructing glyph filenames, egg-mkfont formats a user-supplied glyph pattern (-gp) into a fixed-size stack buffer without length validation. Supplying an excessively long glyph pattern string can overflow the stack buffer, resulting in memory corruption and a deterministic crash. Depending on build configuration and execution environment, the overflow may also be exploitable for arbitrary code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Panda3D \u003c= 1.10.16 egg-mkfont Stack Buffer Overflow","id":"CVE-2026-22189","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Panda3D \u003c= 1.10.16 egg-mkfont Format String Information Disclosure","id":"CVE-2026-22190"},"packages":[],"prev":{"headline":"Panda3D \u003c= 1.10.16 Deploy-Stub Stack Exhaustion via Unbounded alloca()","id":"CVE-2026-22188"},"products":["Panda3D"],"published":"2026-01-07","related":[{"cvss_score":6.9,"headline":"Panda3D \u003c= 1.10.16 Deploy-Stub Stack Exhaustion via Unbounded alloca()","id":"CVE-2026-22188","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":5.1,"headline":"Panda3D \u003c= 1.10.16 egg-mkfont Format String Information Disclosure","id":"CVE-2026-22190","kev_date_added":null,"published":"2026-01-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-14","vendors":["Panda3D"]},"summary":"Attacker can trigger stack buffer overflow in Panda3D egg-mkfont via long glyph patterns, potentially causing crashes or arbitrary code execution.","url":"https://insights.sbomify.com/CVE-2026-22189/"}
