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-2026-26927 in the wild and no public exploit code.\n\nAffected product: Krajowa Izba Rozliczeniowa Szafir SDK Web. 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-2026-26927/ (Markdown: https://insights.sbomify.com/CVE-2026-26927/index.md)","id":"CVE-2026-26927","markdown":"https://insights.sbomify.com/CVE-2026-26927/index.md","name":"CVE-2026-26927","record":{"aliases":["GHSA-v88m-g39w-9rgh"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Szafir SDK Web plugin","requires_auth":"none","summary":"Attackers can spoof the origin URL in Szafir SDK Web to bypass confirmation prompts and execute arbitrary code via SzafirHost.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-348","name":"Use of Less Trusted Source"}],"description":"Szafir SDK Web is a browser plug-in that can run SzafirHost application which download the necessary files when launched.\nIn Szafir SDK Web it is possible to change the URL (HTTP Origin) of the application call location. An unauthenticated attacker can craft a website that is able to launch SzafirHost application with arbitrary arguments via Szafir SDK Web browser addon. No validation will be performed to check whether the address specified in `document_base_url` parameter is in any way related to the actual address of the calling web application. The URL address specified in `document_base_url` parameter is then shown in the application confirmation prompt. When a victim confirms the execution of the application, it will be called in the context of attacker's website URL and might download additional files and libraries from that website. When victim accepts the application execution for the URL showed in the confirmation prompt with the \"remember\" option before, the prompt won't be shown and the application will be called in the context of URL provided by the attacker without any interaction.\n\nThis issue was fixed in version 0.0.17.4.","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":"URL (HTTP Origin) call location spoofing in Szafir SDK Web","id":"CVE-2026-26927","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Lack of Dynamic Library Validation in SzafirHost","id":"CVE-2026-26928"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2026-26899"},"products":["Szafir SDK Web"],"published":"2026-04-02","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":"partial"},"state":"PUBLISHED","updated":"2026-04-02","vendors":["Krajowa Izba Rozliczeniowa"]},"summary":"Attackers can spoof the origin URL in Szafir SDK Web to bypass confirmation prompts and execute arbitrary code via SzafirHost.","url":"https://insights.sbomify.com/CVE-2026-26927/"}
