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-2026-103432 in the wild and no public exploit code.\n\nAffected product: apcupsd. 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-2026-103432/ (Markdown: https://insights.sbomify.com/CVE-2026-103432/index.md)","id":"CVE-2026-103432","markdown":"https://insights.sbomify.com/CVE-2026-103432/index.md","name":"CVE-2026-103432","record":{"aliases":["DEBIAN-CVE-2026-103432","GHSA-mx74-w6g6-vppg","UBUNTU-CVE-2026-103432"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"UPS monitoring software","requires_auth":"none","summary":"A stack-based buffer overflow in apcupsd CGI scripts allows attackers to execute arbitrary code or cause denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/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":"apcupsd through 3.14.14 has an sscanf stack-based buffer overflow in getupsvar() in src/cgi/upsfetch.c (used by upsstats.cgi, multimon.cgi, and upsfstats.cgi), a related issue to CVE-2026-15544.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in apcupsd","id":"CVE-2026-103432","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Bake filesystem entitlement consent is skipped for certain secret and oci-layout definitions","id":"CVE-2026-103433"},"packages":[],"prev":{"headline":"colmux in collectl before 4.3.20.2 does not sanitize ANSI/VT100 terminal escape sequences in data received from remote collectl instances be","id":"CVE-2026-103431"},"products":["apcupsd"],"published":"2026-09-30","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["apcupsd"]},"summary":"A stack-based buffer overflow in apcupsd CGI scripts allows attackers to execute arbitrary code or cause denial of service.","url":"https://insights.sbomify.com/CVE-2026-103432/"}
