An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-28223 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- wagtail (PyPI): affected all versions; fixed in 6.3.8, 7.0.6, 7.2.3\n- wagtail (PyPI): affected all versions; fixed in 6.3.8\n- wagtail (PyPI): affected all versions; fixed in 6.3.8\n- wagtail (PyPI): affected from 6.4rc1; fixed in 7.0.6\n- wagtail (PyPI): affected from 6.4rc1; fixed in 7.0.6\n- wagtail (PyPI): affected from 7.1rc1; fixed in 7.2.3\n- wagtail (PyPI): affected from 7.1rc1; fixed in 7.2.3\n- wagtail (PyPI): affected from 7.3rc1; fixed in 7.3.1\n- wagtail (PyPI): affected from 7.3rc1; fixed in 7.3.1\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-2026-28223/ (Markdown: https://insights.sbomify.com/CVE-2026-28223/index.md)","id":"CVE-2026-28223","markdown":"https://insights.sbomify.com/CVE-2026-28223/index.md","name":"CVE-2026-28223","record":{"aliases":["GHSA-p4v8-rw59-93cq","PYSEC-2026-2308","ROOT-APP-PYPI-CVE-2026-28223"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Wagtail CMS","requires_auth":"high_privilege","summary":"Stored XSS in Wagtail admin allows attackers to execute JavaScript via crafted page titles, potentially hijacking other admin users' sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"wagtail","vendor":"torchbox"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Wagtail is an open source content management system built on Django. Prior to versions 6.3.8, 7.0.6, 7.2.3, and 7.3.1, a stored cross-site scripting (XSS) vulnerability exists on confirmation messages within the wagtail.contrib.simple_translation module. A user with access to the Wagtail admin area may create a page with a specially-crafted title which, when another user performs the \"Translate\" action, causes arbitrary JavaScript code to run. This could lead to performing actions with that user's credentials. The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin. This issue has been patched in versions 6.3.8, 7.0.6, 7.2.3, and 7.3.1.","ecosystems":["PyPI"],"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":"Wagtail: Improper escaping of HTML (Cross-site Scripting) in simple_translation admin interface","id":"CVE-2026-28223","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":9,"n_references":9,"next":{"headline":"Firebird Null Pointer Dereference via CryptCallback causes DOS","id":"CVE-2026-28224"},"packages":[{"ecosystem":"PyPI","fixed":["6.3.8","7.0.6","7.2.3"],"introduced":["0","6.4","7.1"],"last_affected":[],"package":"wagtail","purl":"pkg:pypi/wagtail","source":"PYSEC-2026-2308"},{"ecosystem":"PyPI","fixed":["6.3.8"],"introduced":["0"],"last_affected":[],"package":"wagtail","purl":null,"source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["6.3.8"],"introduced":["0"],"last_affected":[],"package":"wagtail","purl":"pkg:pypi/wagtail","source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.0.6"],"introduced":["6.4rc1"],"last_affected":[],"package":"wagtail","purl":null,"source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.0.6"],"introduced":["6.4rc1"],"last_affected":[],"package":"wagtail","purl":"pkg:pypi/wagtail","source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.2.3"],"introduced":["7.1rc1"],"last_affected":[],"package":"wagtail","purl":null,"source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.2.3"],"introduced":["7.1rc1"],"last_affected":[],"package":"wagtail","purl":"pkg:pypi/wagtail","source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.3.1"],"introduced":["7.3rc1"],"last_affected":[],"package":"wagtail","purl":null,"source":"GHSA-p4v8-rw59-93cq"},{"ecosystem":"PyPI","fixed":["7.3.1"],"introduced":["7.3rc1"],"last_affected":[],"package":"wagtail","purl":"pkg:pypi/wagtail","source":"GHSA-p4v8-rw59-93cq"}],"prev":{"headline":"Wagtail: Improper escaping of HTML (Cross-site Scripting) on TableBlock class attributes","id":"CVE-2026-28222"},"products":["wagtail"],"published":"2026-03-05","related":[{"cvss_score":7.3,"headline":"Wagtail: Reflected XSS in dynamic image URL generator view","id":"CVE-2026-54263","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":6.5,"headline":"Wagtail: Improper permission handling in image preview","id":"CVE-2026-54261","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":6.5,"headline":"Wagtail: Improper permission handling when comparing revisions","id":"CVE-2026-44197","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":6.5,"headline":"Wagtail: Improper permission handling when deleting form submissions","id":"CVE-2026-44199","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":6.5,"headline":"Wagtail: Improper permission handling when copying pages","id":"CVE-2026-44200","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":6.5,"headline":"Wagtail regular expression denial-of-service via search query parsing","id":"CVE-2024-39317","kev_date_added":null,"published":"2024-07-11"},{"cvss_score":6.4,"headline":"Wagtail vulnerable to stored Cross-site Scripting attack via ModelAdmin views","id":"CVE-2023-28836","kev_date_added":null,"published":"2023-04-03"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"total"},"state":"PUBLISHED","updated":"2026-03-06","vendors":["wagtail"]},"summary":"Stored XSS in Wagtail admin allows attackers to execute JavaScript via crafted page titles, potentially hijacking other admin users' sessions.","url":"https://insights.sbomify.com/CVE-2026-28223/"}
