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-2026-6858 in the wild and no public exploit code.\n\nAffected product: Unknown Transbank Webpay. 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-2026-6858/ (Markdown: https://insights.sbomify.com/CVE-2026-6858/index.md)","id":"CVE-2026-6858","markdown":"https://insights.sbomify.com/CVE-2026-6858/index.md","name":"CVE-2026-6858","record":{"aliases":["GHSA-4c54-mjrj-jwj4"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious scripts into logs, leading to stored XSS and potential administrator account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Transbank Webpay WordPress plugin before 1.14.0 does not sanitize and escape logs to be displayed, allowing unauthenticated users to perform Stored XSS attacks against logged in administrator","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":"Transbank Webpay \u003c 1.14.0 - Unauthenticated Stored XSS","id":"CVE-2026-6858","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Instructlab: instructlab: arbitrary code execution due to hardcoded `trust_remote_code=true`","id":"CVE-2026-6859"},"packages":[],"prev":{"headline":"Camel-infinispan: camel-infinispan: remote code execution via unsafe deserialization","id":"CVE-2026-6857"},"products":["Transbank Webpay"],"published":"2026-06-22","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":"2026-07-22","vendors":["Unknown"]},"summary":"Unauthenticated attackers can inject malicious scripts into logs, leading to stored XSS and potential administrator account takeover.","url":"https://insights.sbomify.com/CVE-2026-6858/"}
