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-2026-9809 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mautic/core (Packagist): affected from 7.0.0; fixed in 7.1.2\n- mautic/core (Packagist): affected from 7.0.0; fixed in 7.1.2\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-2026-9809/ (Markdown: https://insights.sbomify.com/CVE-2026-9809/index.md)","id":"CVE-2026-9809","markdown":"https://insights.sbomify.com/CVE-2026-9809/index.md","name":"CVE-2026-9809","record":{"aliases":["GHSA-7h65-whp7-rgqf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Mautic marketing automation","requires_auth":"low_privilege","summary":"Authenticated users can inject scripts into project tags, allowing attackers to execute code in admin sessions to take over accounts or steal data.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mautic","cpe":[],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A stored Cross-Site Scripting (XSS) vulnerability exists in the Projects component of Mautic 7. When displaying project tags and popovers on administrative detail views (such as campaigns, emails, or forms), user-supplied project names are rendered without proper sanitization. An authenticated user with permissions to create or edit projects can exploit this to inject malicious script payloads. When an administrative user views an entity associated with a compromised project and hovers over its tag, the injected script executes within the context of their active browser session. This could allow an attacker to perform administrative actions on behalf of the victim, alter system configurations, or exfiltrate sensitive data.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":"2026-08-02","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-08-02T12:21:38Z","kind":"github_poc","ref":"https://github.com/aj2108/CVE-2026-9809","stars":0,"title":"CVE-2026-9809 is a Stored Cross-Site Scripting (Stored XSS) vulnerability affecting Mautic 7 (versions 7.0.0 through 7.1.1)."}],"tier":"poc_unverified"},"has_fix":true,"headline":"Mautic has Stored Cross-Site Scripting (XSS) in Projects Component","id":"CVE-2026-9809","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"AI Chatbot \u0026 Workflow Automation by AIWU \u003c 1.5.4 - Unauthenticated Privilege Escalation via MCP OAuth","id":"CVE-2026-9810"},"packages":[{"ecosystem":"Packagist","fixed":["7.1.2"],"introduced":["7.0.0"],"last_affected":[],"package":"mautic/core","purl":null,"source":"GHSA-7h65-whp7-rgqf"},{"ecosystem":"Packagist","fixed":["7.1.2"],"introduced":["7.0.0"],"last_affected":[],"package":"mautic/core","purl":"pkg:composer/mautic/core","source":"GHSA-7h65-whp7-rgqf"}],"prev":{"headline":"Mautic has an Authorization Bypass in API v2 Endpoints","id":"CVE-2026-9808"},"products":[],"published":"2026-05-29","related":[],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-29","vendors":[]},"summary":"Authenticated users can inject scripts into project tags, allowing attackers to execute code in admin sessions to take over accounts or steal data.","url":"https://insights.sbomify.com/CVE-2026-9809/"}
