Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33051 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- craftcms/cms (Packagist): affected from 5.9.0-beta.1; fixed in 5.9.11\n- craftcms/cms (Packagist): affected from 5.9.0-beta.1; fixed in 5.9.11\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-2026-33051/ (Markdown: https://insights.sbomify.com/CVE-2026-33051/index.md)","id":"CVE-2026-33051","markdown":"https://insights.sbomify.com/CVE-2026-33051/index.md","name":"CVE-2026-33051","record":{"aliases":["GHSA-3x4w-mxpf-fhqq"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Craft CMS","requires_auth":"low_privilege","summary":"Low-privileged users can inject scripts via profile names to escalate privileges to administrator in Craft CMS.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"craft_cms","vendor":"craftcms"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Craft CMS is a content management system (CMS). In versions 5.9.0-beta.1 through 5.9.10, the revision/draft context menu in the element editor renders the creator’s fullName as raw HTML due to the use of Template::raw() combined with Craft::t() string interpolation. A low-privileged control panel user (e.g., Author) can set their fullName to an XSS payload via the profile editor, then create an entry with two saves. If an administrator is logged in and executes a specifically crafted payload while an elevated session is active, the attacker’s account can be elevated to administrator.
