Avira Internet Security, published on 5 Mar 2026. 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-2026-27748 exists.\n\nAffected product: Gen Digital Inc. Avira Internet Security. 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-2026-27748/ (Markdown: https://insights.sbomify.com/CVE-2026-27748/index.md)","id":"CVE-2026-27748","markdown":"https://insights.sbomify.com/CVE-2026-27748/index.md","name":"CVE-2026-27748","record":{"aliases":["GHSA-w3vx-x8fj-r29m"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Avira Internet Security","requires_auth":"low_privilege","summary":"Local attackers can exploit improper link resolution in the Software Updater to delete arbitrary files with SYSTEM privileges, potentially leading to privilege escalation or denial of service.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"internet_security","vendor":"avira"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Avira Internet Security contains an improper link resolution vulnerability in the Software Updater component. During the update process, a privileged service running as SYSTEM deletes a file under C:\\\\ProgramData without validating whether the path resolves through a symbolic link or reparse point. A local attacker can create a malicious link to redirect the delete operation to an arbitrary file, resulting in deletion of attacker-chosen files with SYSTEM privileges. This may lead to local privilege escalation, denial of service, or system integrity compromise depending on the targeted file and operating system configuration.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Avira Internet Security Arbitrary File Deletion via Improper Link Resolution","id":"CVE-2026-27748","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Avira Internet Security System Speedup Insecure Deserialization","id":"CVE-2026-27749"},"packages":[],"prev":{"headline":"SPIP interface_traduction_objets \u003c 2.2.2 Authenticated SQL Injection","id":"CVE-2026-27747"},"products":["Avira Internet Security"],"published":"2026-03-05","related":[{"cvss_score":7.8,"headline":"Avira Internet Security System Speedup Insecure Deserialization","id":"CVE-2026-27749","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":7.8,"headline":"Avira Internet Security Optimizer TOCTOU","id":"CVE-2026-27750","kev_date_added":null,"published":"2026-03-05"}],"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":"total"},"state":"PUBLISHED","updated":"2026-04-01","vendors":["Gen Digital Inc."]},"summary":"Local attackers can exploit improper link resolution in the Software Updater to delete arbitrary files with SYSTEM privileges, potentially leading to privilege escalation or denial of service.","url":"https://insights.sbomify.com/CVE-2026-27748/"}
