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-2026-22904 in the wild and no public exploit code.\n\nAffected product: WAGO 0852-1322. 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-2026-22904/ (Markdown: https://insights.sbomify.com/CVE-2026-22904/index.md)","id":"CVE-2026-22904","markdown":"https://insights.sbomify.com/CVE-2026-22904/index.md","name":"CVE-2026-22904","record":{"aliases":["GHSA-p2hc-xm25-6rh8"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"lighttpd web server","requires_auth":"none","summary":"Unauthenticated attackers can cause denial of service or remote code execution via stack buffer overflow in lighttpd cookie parsing.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Improper length handling when parsing multiple cookie fields (including TRACKID) allows an unauthenticated remote attacker to send oversized cookie values and trigger a stack buffer overflow, resulting in a denial‑of‑service condition and possible remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Stack Overflow via Oversized Cookie Fields in lighttpd","id":"CVE-2026-22904","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Authentication Bypass via URI Traversal","id":"CVE-2026-22905"},"packages":[],"prev":{"headline":"Stack Overflow via SESSIONID Cookie in lighttpd","id":"CVE-2026-22903"},"products":["0852-1322","0852-1328"],"published":"2026-02-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-09","vendors":["WAGO"]},"summary":"Unauthenticated attackers can cause denial of service or remote code execution via stack buffer overflow in lighttpd cookie parsing.","url":"https://insights.sbomify.com/CVE-2026-22904/"}
