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-2026-27750 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-2026-27750/ (Markdown: https://insights.sbomify.com/CVE-2026-27750/index.md)","id":"CVE-2026-27750","markdown":"https://insights.sbomify.com/CVE-2026-27750/index.md","name":"CVE-2026-27750","record":{"aliases":["GHSA-qfjh-mfrq-8j64"],"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":"A local attacker can exploit a TOCTOU race condition in Avira's Optimizer to delete protected system files, leading to privilege escalation or denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"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-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Avira Internet Security contains a time-of-check time-of-use (TOCTOU) vulnerability in the Optimizer component. A privileged service running as SYSTEM identifies directories for cleanup during a scan phase and subsequently deletes them during a separate cleanup phase without revalidating the target path. A local attacker can replace a previously scanned directory with a junction or reparse point before deletion occurs, causing the privileged process to delete an unintended system location. This may result in deletion of protected files or directories and can lead to local privilege escalation, denial of service, or system integrity compromise depending on the affected target.","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 Optimizer TOCTOU","id":"CVE-2026-27750","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"SODOLA SL902-SWTGW124AS \u003c= 200.1.20 Use of Default Credentials","id":"CVE-2026-27751"},"packages":[],"prev":{"headline":"Avira Internet Security System Speedup Insecure Deserialization","id":"CVE-2026-27749"},"products":["Avira Internet Security"],"published":"2026-03-05","related":[{"cvss_score":7.8,"headline":"Avira Internet Security Arbitrary File Deletion via Improper Link Resolution","id":"CVE-2026-27748","kev_date_added":null,"published":"2026-03-05"},{"cvss_score":7.8,"headline":"Avira Internet Security System Speedup Insecure Deserialization","id":"CVE-2026-27749","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":"A local attacker can exploit a TOCTOU race condition in Avira's Optimizer to delete protected system files, leading to privilege escalation or denial of service.","url":"https://insights.sbomify.com/CVE-2026-27750/"}
