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-2023-48219 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- TinyMCE (NuGet): affected all versions; fixed in 5.10.9\n- TinyMCE (NuGet): affected all versions; fixed in 5.10.9\n- TinyMCE (NuGet): affected from 6.0.0; fixed in 6.7.3\n- TinyMCE (NuGet): affected from 6.0.0; fixed in 6.7.3\n- tinymce/tinymce (Packagist): affected all versions; fixed in 5.10.9\n- tinymce/tinymce (Packagist): affected all versions; fixed in 5.10.9\n- tinymce/tinymce (Packagist): affected from 6.0.0; fixed in 6.7.3\n- tinymce/tinymce (Packagist): affected from 6.0.0; fixed in 6.7.3\n- tinymce (npm): affected all versions; fixed in 5.10.9\n- tinymce (npm): affected all versions; fixed in 5.10.9\n- tinymce (npm): affected from 6.0.0; fixed in 6.7.3\n- tinymce (npm): affected from 6.0.0; fixed in 6.7.3\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-2023-48219/ (Markdown: https://insights.sbomify.com/CVE-2023-48219/index.md)","id":"CVE-2023-48219","markdown":"https://insights.sbomify.com/CVE-2023-48219/index.md","name":"CVE-2023-48219","record":{"aliases":["GHSA-v626-r774-j7f8","UBUNTU-CVE-2023-48219"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TinyMCE rich text editor","requires_auth":"none","summary":"Attackers can execute arbitrary scripts via mutation XSS in TinyMCE's undo/redo functionality by exploiting unescaped text nodes.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tinymce","vendor":"tiny"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"TinyMCE is an open source rich text editor. A mutation cross-site scripting (mXSS) vulnerability was discovered in TinyMCE’s core undo/redo functionality and other APIs and plugins. Text nodes within specific parents are not escaped upon serialization according to the HTML standard. If such text nodes contain a special character reserved as an internal marker, they can be combined with other HTML patterns to form malicious snippets. These snippets pass the initial sanitisation layer when the content is parsed into the editor body, but can trigger XSS when the special internal marker is removed from the content and re-parsed. his vulnerability has been patched in TinyMCE versions 6.7.3 and 5.10.9. Users are advised to upgrade. There are no known workarounds for this vulnerability.","ecosystems":["NuGet","Packagist","npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Special characters in unescaped text nodes can trigger mXSS in TinyMCE","id":"CVE-2023-48219","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"NuGet","product":null,"products":[],"type":"xss","year":"2023"},"n_packages":12,"n_references":3,"next":{"headline":"Decidim's devise_invitable gem vulnerable to circumvention of invitation token expiry period","id":"CVE-2023-48220"},"packages":[{"ecosystem":"NuGet","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"TinyMCE","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"NuGet","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"TinyMCE","purl":"pkg:nuget/TinyMCE","source":"GHSA-v626-r774-j7f8"},{"ecosystem":"NuGet","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"TinyMCE","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"NuGet","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"TinyMCE","purl":"pkg:nuget/TinyMCE","source":"GHSA-v626-r774-j7f8"},{"ecosystem":"Packagist","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"tinymce/tinymce","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"Packagist","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"tinymce/tinymce","purl":"pkg:composer/tinymce/tinymce","source":"GHSA-v626-r774-j7f8"},{"ecosystem":"Packagist","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"tinymce/tinymce","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"Packagist","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"tinymce/tinymce","purl":"pkg:composer/tinymce/tinymce","source":"GHSA-v626-r774-j7f8"},{"ecosystem":"npm","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"tinymce","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"npm","fixed":["5.10.9"],"introduced":["0"],"last_affected":[],"package":"tinymce","purl":"pkg:npm/tinymce","source":"GHSA-v626-r774-j7f8"},{"ecosystem":"npm","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"tinymce","purl":null,"source":"GHSA-v626-r774-j7f8"},{"ecosystem":"npm","fixed":["6.7.3"],"introduced":["6.0.0"],"last_affected":[],"package":"tinymce","purl":"pkg:npm/tinymce","source":"GHSA-v626-r774-j7f8"}],"prev":{"headline":"Bypass of field access control in strapi-plugin-protected-populate","id":"CVE-2023-48218"},"products":["tinymce"],"published":"2023-11-15","related":[{"cvss_score":8.7,"headline":"TinyMCE Cross-Site Scripting (XSS) vulnerability using through data-mce- prefixed src, href, style attributes","id":"CVE-2026-47759","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":8.7,"headline":"TinyMCE Cross-Site Scripting (XSS) vulnerability using sanitization bypass through nested SVGs","id":"CVE-2026-47760","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":8.7,"headline":"TinyMCE Cross-Site Scripting (XSS) vulnerability using media plugin `data-mce-object` injection","id":"CVE-2026-47761","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":8.7,"headline":"TinyMCE Cross-Site Scripting (XSS) vulnerability through `mce:protected` comments","id":"CVE-2026-47762","kev_date_added":null,"published":"2026-05-28"},{"cvss_score":6.1,"headline":"Cross-site scripting vulnerability in TinyMCE","id":"CVE-2024-21908","kev_date_added":null,"published":"2024-01-03"},{"cvss_score":6.1,"headline":"Cross-site scripting vulnerability in TinyMCE plugins","id":"CVE-2024-21910","kev_date_added":null,"published":"2024-01-03"},{"cvss_score":6.1,"headline":"Cross-site scripting vulnerability in TinyMCE","id":"CVE-2024-21911","kev_date_added":null,"published":"2024-01-03"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-29","vendors":["tinymce"]},"summary":"Attackers can execute arbitrary scripts via mutation XSS in TinyMCE's undo/redo functionality by exploiting unescaped text nodes.","url":"https://insights.sbomify.com/CVE-2023-48219/"}
