An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-48092 exists.\n\nAffected product: mcmilk 7-Zip. 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-2026-48092/ (Markdown: https://insights.sbomify.com/CVE-2026-48092/index.md)","id":"CVE-2026-48092","markdown":"https://insights.sbomify.com/CVE-2026-48092/index.md","name":"CVE-2026-48092","record":{"aliases":["ALPINE-CVE-2026-48092","DEBIAN-CVE-2026-48092","ECHO-5aa5-e5e2-e8ee","MINI-fx8h-jcj7-4w3m","UBUNTU-CVE-2026-48092"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"7-Zip archiver","requires_auth":"none","summary":"An integer overflow in 7-Zip's SquashFS handler on 32-bit builds allows attackers to read heap memory via crafted archives.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"7-zip","vendor":"7-zip"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"7-Zip is a file archiver with a high compression ratio. Versions 9.34 through 26.00 contain a heap memory disclosure via SquashFS fragment offset integer overflow on 32-bit builds. 32-bit integer overflow in the SquashFS ReadBlock function allows an attacker-controlled node.Offset value to bypass the fragment bounds check, causing memcpy to read heap memory preceding the cache buffer into the extracted file. The vulnerability is exploitable only on 32-bit builds of 7-Zip where size_t is 32 bits, allowing the addition offsetInBlock + blockSize to wrap modulo 2³². On 64-bit builds the addition is promoted to 64 bits and the check correctly rejects the input. Version 26.01 patches the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"7-Zip SquashFS Fragment Offset Overflow (GHSL-2026-116)","id":"CVE-2026-48092","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Code Embed - Contributor Stored Cross-Site Scripting via Remote URL Embed","id":"CVE-2026-48093"},"packages":[],"prev":{"headline":"Further research determined the issue is not a vulnerability.","id":"CVE-2026-48091"},"products":["7-Zip"],"published":"2026-06-05","related":[{"cvss_score":7,"headline":"7-Zip Mark of the Web Bypass","id":"CVE-2025-0411","kev_date_added":"2025-02-06","published":"2025-01-25"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2008-6536","kev_date_added":null,"published":"2009-03-30"},{"cvss_score":8.8,"headline":"GHSL-2026-140_7-Zip: 7-Zip has a heap buffer overflow via NTFS compressed stream buffer under-allocation","id":"CVE-2026-48095","kev_date_added":null,"published":"2026-06-05"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2018-10172","kev_date_added":null,"published":"2018-04-16"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2016-2335","kev_date_added":null,"published":"2016-06-07"},{"cvss_score":7.8,"headline":"7-Zip Zstandard Decompression Integer Underflow Remote Code Execution Vulnerability","id":"CVE-2024-11477","kev_date_added":null,"published":"2024-11-22"},{"cvss_score":7.8,"headline":"7-Zip SquashFS File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2023-40481","kev_date_added":null,"published":"2024-05-03"}],"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":"2026-06-08","vendors":["mcmilk"]},"summary":"An integer overflow in 7-Zip's SquashFS handler on 32-bit builds allows attackers to read heap memory via crafted archives.","url":"https://insights.sbomify.com/CVE-2026-48092/"}
