Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77129 in the wild and no public exploit code.\n\nAffected product: TYPO3 Extension \"Event management and registration\". 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-2026-77129/ (Markdown: https://insights.sbomify.com/CVE-2026-77129/index.md)","id":"CVE-2026-77129","markdown":"https://insights.sbomify.com/CVE-2026-77129/index.md","name":"CVE-2026-77129","record":{"aliases":["GHSA-j8g2-q9pf-89w3"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TYPO3 extension","requires_auth":"low_privilege","summary":"Authenticated backend users can inject Fluid template code to disclose data or execute TypoScript objects in the Event management extension.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"TYPO3","cpe":[],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1336","name":"Improper Neutralization of Special Elements Used in a Template Engine"}],"description":"The extension passes an editor-configurable email subject string directly into a Fluid template source without restriction.
