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-2026-1698 in the wild and no public exploit code.\n\nAffected product: arcinfo PcVue. 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-2026-1698/ (Markdown: https://insights.sbomify.com/CVE-2026-1698/index.md)","id":"CVE-2026-1698","markdown":"https://insights.sbomify.com/CVE-2026-1698/index.md","name":"CVE-2026-1698","record":{"aliases":["GHSA-35x7-r658-wx7f"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA web application","requires_auth":"none","summary":"Remote attackers can manipulate server-side behavior via HTTP Host header injection in PcVue web applications, potentially bypassing security controls.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"arcinfo","cpe":[{"product":"pcvue","vendor":"arcinfo"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:N/SC:L/SI:L/SA:N/AU:Y/R:U/RE:M/U:Clear","version":"4.0"},"cwes":[{"id":"CWE-644","name":"Improper Neutralization of HTTP Headers for Scripting Syntax"}],"description":"A HTTP Host header attack vulnerability affects WebClient and the WebScheduler web apps of PcVue in version 15.0.0 through 16.3.3 included, allowing a remote attacker to inject harmful payloads that manipulate server-side behavior.\n\nThis vulnerability only affects the endpoints /Authentication/ExternalLogin, /Authentication/AuthorizationCodeCallback and /Authentication/Logout\nof the WebClient and WebScheduler web apps.","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":"HTTP Host header vulnerability in WebClient and WebScheduler web apps","id":"CVE-2026-1698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Code injection in Eclipse Theia - Website","id":"CVE-2026-1699"},"packages":[],"prev":{"headline":"Use of unsecure cookies for GraphicalData web service and WebClient web app","id":"CVE-2026-1697"},"products":["PcVue"],"published":"2026-02-26","related":[{"cvss_score":9.8,"headline":"ARC Informatique PcVue Deserialization of Untrusted Data","id":"CVE-2020-26867","kev_date_added":null,"published":"2020-10-12"},{"cvss_score":8.4,"headline":"Weak encryption mechanism for User directory","id":"CVE-2026-14868","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":7.5,"headline":"ARC Informatique PcVue Access to Critical Private Variable via Public Method","id":"CVE-2020-26868","kev_date_added":null,"published":"2020-10-12"},{"cvss_score":7.5,"headline":"ARC Informatique PcVue Exposure of Sensitive Information to an Unauthorized Actor","id":"CVE-2020-26869","kev_date_added":null,"published":"2020-10-12"},{"cvss_score":6.8,"headline":"Insecure password storage in User directory","id":"CVE-2026-14867","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":5.5,"headline":"Information disclosure in PcVue","id":"CVE-2022-4312","kev_date_added":null,"published":"2022-12-12"},{"cvss_score":5.5,"headline":"ARC Informatique PcVue","id":"CVE-2022-2569","kev_date_added":null,"published":"2022-08-24"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-03-26","vendors":["arcinfo"]},"summary":"Remote attackers can manipulate server-side behavior via HTTP Host header injection in PcVue web applications, potentially bypassing security controls.","url":"https://insights.sbomify.com/CVE-2026-1698/"}
