Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-6486 in the wild and no public exploit code.\n\nAffected product: classroombookings. 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-2026-6486/ (Markdown: https://insights.sbomify.com/CVE-2026-6486/index.md)","id":"CVE-2026-6486","markdown":"https://insights.sbomify.com/CVE-2026-6486/index.md","name":"CVE-2026-6486","record":{"aliases":["GHSA-376w-pjjp-jrvj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"classroombookings","requires_auth":"low_privilege","summary":"Remote attackers can inject malicious scripts via the user display name field in classroombookings, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A vulnerability was detected in classroombookings up to 2.17.0. This impacts the function read of the file crbs-core/application/views/layout.php of the component User Display Name Handler. The manipulation of the argument displayname results in cross site scripting. The attack can be executed remotely. The exploit is now public and may be used. Upgrading to version 2.17.1 will fix this issue. The patch is identified as 69c3c9bb8a17f1ea572d8f4502bf238f0214c98a. It is suggested to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"classroombookings User Display Name layout.php read cross site scripting","id":"CVE-2026-6486","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Qihui jtbc5 CMS Code Endpoint manage.php path traversal","id":"CVE-2026-6487"},"packages":[],"prev":{"headline":"UEFI BIOS embedded Shell can be used to bypass Secure Boot","id":"CVE-2026-6485"},"products":["classroombookings"],"published":"2026-04-17","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":"2026-04-18","vendors":["n/a"]},"summary":"Remote attackers can inject malicious scripts via the user display name field in classroombookings, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2026-6486/"}
