An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-55729 in the wild and no public exploit code.\n\nAffected product: Loytec LWEB-802. 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-2026-55729/ (Markdown: https://insights.sbomify.com/CVE-2026-55729/index.md)","id":"CVE-2026-55729","markdown":"https://insights.sbomify.com/CVE-2026-55729/index.md","name":"CVE-2026-55729","record":{"aliases":["GHSA-c4x3-39wp-wf7p"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Loytec LWEB-802","requires_auth":"none","summary":"An unauthenticated remote attacker can leak stored management credentials from browser localStorage via a crafted link in Loytec LWEB-802.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"NCSC.ch","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of Sensitive Information (CWE-200) in LWEB802 browser `localStorage` in Loytec LWEB-802 before 5.0.8 on all platforms allows an unauthenticated remote attacker to leak stored management credentials via a crafted link.","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":"Loytec LWEB802: Exposure of Sensitive Information in browser localStorage","id":"CVE-2026-55729","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Loytec LWEB802: Reflected Cross-Site Scripting in LWEB802","id":"CVE-2026-55730"},"packages":[],"prev":{"headline":"Loytec LINX firmware: Stack-based Buffer Overflow in cmd_ipaddr_conflict","id":"CVE-2026-55728"},"products":["LWEB-802"],"published":"2026-07-24","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":"2026-07-24","vendors":["Loytec"]},"summary":"An unauthenticated remote attacker can leak stored management credentials from browser localStorage via a crafted link in Loytec LWEB-802.","url":"https://insights.sbomify.com/CVE-2026-55729/"}
